Lymphangioma circumscriptum is a rare congenital proliferation of lymphatic vessels that may occur anywhere on the skin and mucous membranes. Based on the depth and the size of abnormal lymph vessels, these lesions are divided into two groups: the superficial vesicles are called lymphangioma circumscriptum and the more deep-seated group includes cavernous lymphangioma, cystic hygroma, and benign lymphangioendothelioma. The differential diagnosis of lymphangioma includes herpes zoster, herpes simplex, molluscum contagiosum, cutaneous melanoma, dermatitis herpetiformis, and viral warts. Herein, we report a rare case of giant cutaneous lymphangioma circumscriptum with emphasis on histopathology and differential diagnosis. Our case was a 14-year-old boy with a history of multiple, clear, pink, red, and brown vesicles protruded as a patch of wart-like growths on the flank’s skin since the 6 months of age. Histopathologic examination indicated presence of multiple thin-walled dilated lymphatic spaces in the papillary dermis lined with a single layer of endothelial cells filled with finely granular hyaline material.

Abstract
Background: The complete blood count (CBC) profile has been found extremely useful in monitoring the growth of SARS-CoV-2 infection; however, predictive CBC parameters that could be used in the management of the disease may vary in different populations.
Methods: This study comparatively analyzed the CBC profile of SARS-CoV-2 patients (N = 75; confirmed positive by real-time polymerase chain reaction [PCR]) and healthy individuals (confirmed negative by real-time PCR) from Kashmir (north India).
Results: Compared with healthy individuals, most of the CBC parameters (hemoglobin levels [13.43 vs 10.9 g/dL; P = 0.0001], lymphocytes [16.04% vs 30.8%; P = 0.00001], monocytes [5.53% vs 7.53%; P = 0.009], and platelet count [150 vs 186 ×103 µL; P = 0.037]) were significantly low in SARS-CoV-2 infected patients, while neutrophilia was more common in infected patients (76.77% vs 59.26%). Among derived parameters, the neutrophil-to-lymphocyte ratio (NLR; 7.31 vs 2.04; P = 0.001) and derived NLR (d-NLR; 4.43 vs 1.5; P = 0.0002) were significantly high in SARS-CoV-2 patients. Further correlation analysis revealed a significant association of neutrophilia with the severity of the disease in SARS-CoV-2 infected patients. Moreover, receiver operating characteristic (ROC) analysis of derived CBC parameters (NLR, d-NLR, and platelet‐to-lymphocyte ratio [PLR] with disease severity and disease outcome) revealed d-NLR as better predictive marker of disease severity (area under the curve [AUC] = 0.658) and disease outcome (AUC = 0.766) compared to PLR with disease severity (AUC = 0.645) and disease outcome (AUC = 0.693).
Conclusion: We therefore conclude, of the CBC parameters neutrophilia as the marker of disease severity and among derived parameters, d-NLR as an early predictive biomarker of both disease severity and poor disease outcome in SARS-CoV-2 patients.

Abstract
Background: ‘M’ proteins or paraproteins refer to immunoglobulins that are produced by clonal plasma cells and are a characteristic feature of monoclonal gammopathies. Routine electrophoresis on agarose gel and immunofixation can be used to detect immunoglobulin paraprotein (M-protein). We aimed to evaluate the performance of agarose gel electrophoresis alone and in combination with immunofixation for detecting serum M-proteins.
Methods: One hundred and twenty-three patients suspected of paraproteinemia were evaluated. Routine serum protein electrophoresis (SPE) and immunofixation electrophoresis (IFE) protocols were performed. Data from SPE, and SPE-IFE (gel images and electrophoretograms) were collected and reviewed.
Results: 21% cases were confirmed using the SPE-IFE combination, and among them, 33% had positive light chain (λ) only on IFE. Similarly, nine cases with biclonal gammopathy on SPE were characterized by IFE.
Conclusion: IFE can be a confirmatory test in cases where SPE results are not reliable and it can be a complementary test when characterization of the M protein detected on SPE is required.

Abstract
Background: Escherichia coli consists of a wide range of strains with huge diversity in their genome, distributed in nature and the alimentary tracts of animals and humans. This study analyzed the phylogenetic group determination and genetic diversity of E. coli strains isolated from domestic animals and human clinical samples.
Methods: Twenty E. coli isolates from domestic animals were analyzed for phylogenetic grouping. Also, 100 clinical samples and 20 animal samples were evaluated by the enterobacterial repetitive intergenic consensus–polymerase chain reaction (ERIC-PCR) technique. The results and the similarity between the strains were determined based on the Dice similarity coefficient in the SAHN program of the NTSYS-pc software.
Results: The frequency of phylogroups among animal samples were A = 5%, B1 = 65%, B2 = 20%, and D = 10%. Based on the ERIC-PCR results, the clinical strains were allocated into 19 clusters. Most strains were in the E7 cluster. Fifty percent of the E. coli isolated from animal specimens belonged to the E4 group, and the lowest number of strains was in the E3 and E5 (1 strain) groups.
Conclusion: The results confirmed the efficiency and usefulness of the ERIC-PCR tool for the identification and classification of bacteria. Also, we demonstrated the most phylogroup among animal samples.

Abstract
Background: This study aimed to investigate the effect of four weeks of selected endurance training on neurotrophin-3 (NT-3) and tropomyosin receptor kinase C (TrkC) gene expression in hippocampal areas of rats with spinal cord injury (SCI).
Methods: In this experimental study, the rats were separated into six equal groups. First, the animals were put under general anesthesia and had their SCI. Then, for four weeks, they were subjected to two kinds of endurance training programs. However, the control injury group received no intervention or training. Following the completion of the training regimes, molecular tests were done using the qRT-PCR technique to evaluate changes in the gene expression of NT-3 and TrkC from the animals' hippocampus.
Results: The expression of NT-3 and TrkC genes were significantly reduced in the SCI model compared to the healthy control group, but it was increased in the SCI + exercise 1 and SCI + exercise 2 groups compared to the SCI group. NT-3 levels did not vary significantly between the SCI + exercise 1 and SCI + exercise 2 groups, although alterations in TrkC levels altered.
Conclusion: In addition to enhancing locomotion in animals with SCI, the endurance training regimens in this research were effective on the expression of NT-3 and TrkC genes and may play a role in axonal development and neuronal survival in SCI recovery.

Abstract
Background: The understanding of blood group phenotypes is currently limited to the ABO and Rh blood group systems. This study aimed to determine the frequency of Rh system antigens (D, C, c, E, e) and the phenotypes of the system in blood donors. Identifying the blood group phenotypes of donors in any population is important for improving healthcare services and better serving patients.
Methods: This descriptive study was carried out on 575 donors (Turkmen and Fars) in blood transfusion centers in Golestan Province, Iran. A cell suspension (3-5%) from each sample was prepared in normal saline and exposed to Rh system antisera using the haemagglutination technique. The Rh phenotype was then determined based on the most common genotype.
Results: For the Rh system, the antigen frequencies of D, C, c, E, and e were 87.76%, 73.6%, 72.1%, 30.83%, and 93.59%, respectively. The most common phenotypes among the Turkmen and Fars donors were R1R1, R1r, and rr, respectively, while the least common phenotypes were R2Rz and ryry. The phenotypes r'r' and ryry were not detected in the Turkmen donors, and the phenotype r''r' was not identified in the Fars donors.
Conclusion: Identifying the prevalence of blood group antigens in donors from each region is crucial for organizing negative antigen blood units, preparing compatible blood for multitransfused patients, and preventing the development of alloantibodies in these patients.

Abstract
Background: Syphilis has serious consequences for human health and poses challenges for biological diagnosis. Techniques such as chemiluminescence are still poorly known in our context. Our objective was to compare chemiluminescence and hemagglutination assays with immunoblot as a reference test for detecting anti-Treponema pallidum antibodies.
Methods: Anti-Treponema pallidum antibodies were detected in serum samples. Comparison of chemiluminescence and hemagglutination assays was carried out with immunoblot as the reference test, based on sensitivity, specificity, positive and negative predictive values, and kappa statistic, using IBM-SPSS version 24 software. The significance level was set at 5%.
Results: A total of 600 participants were recruited, with a prevalence of syphilis infection of 3%. Sensitivity and specificity were 100% and 96.2% for chemiluminescence, and 93.8% and 100% for hemagglutination, respectively. Cohen's kappa statistic between the two tests showed satisfactory agreement (0.768). Cohen's kappa agreements between chemiluminescence/immunoblot and plate hemagglutination assay/immunoblot were greater than 0.8, indicating excellent agreement with the reference test (p<0.0001).
Conclusion: Chemiluminescence is more sensitive but less specific than hemagglutination. The use of chemiluminescence as a first-line test for the diagnosis of syphilis should be considered.

Abstract
Background: Staphylococcus aureus is one of the most common agents of nosocomial infection worldwide. Methicillin-resistant and biofilm-associated infections of this bacterium have become a clinical concern in patients. This research aimed to identify biofilm-forming ability and accessory gene regulator (Agr) - specific group of clinical isolates of methicillin-resistant S. aureus (MRSA) in Northern Iran.
Methods: In 2021, a total of 200 clinical isolates were identified as S. aureus by biochemical tests. The disk diffusion method was used to examine the antibiotic resistance of isolates and the microplate method was applied to investigate the biofilm production capability. In addition, the PCR method was used to determine the frequency of biofilm-associated genes and Agr typing of MRSA isolates. P £ 0.05 was considered significant.
Results: Overall, 62.5% of isolates were methicillin-resistant and 75% were multiple antibiotic-resistant. Biofilm-forming ability was detected in 99 (79.2%) methicillin-resistant isolates in which icaA and icaD were found in 85% and 78% of biofilm-producing isolates, respectively. Type 1 of the Agr gene was the most common type among methicillin-resistant isolates. The frequency of biofilm-associated genes showed a significant association with MDR phenotype and the presence of Agr locus (P £ 0.05).
Conclusion: The present findings indicate a high frequency of biofilm and antibacterial resistance in methicillin-resistant S. aureus isolates in Guilan Province. These findings suggest reliable and rapid identification of biofilm-forming MRSA strains to prevent the spread of these bacteria.

Abstract
Background: Acute ischemic stroke occurs when blood clots obstruct blood vessels within the brain. Platelets (Plts) are integral to the pathophysiology of stroke. This research aimed to explore the relationship between Plt quality and Plt indices in the context of acute ischemic stroke.
Methods: This cross-sectional investigation involved 100 patients diagnosed with acute ischemic stroke at Kosti Teaching Hospital and Alyammama Hospitals. The diagnosis was confirmed using brain CT imaging and electrocardiography (ECG). Blood samples were collected in EDTA-containing tubes within 24 hours following the commencement of treatment and were subsequently analyzed for Plt count, mean Plt volume (MPV), Plt distribution width (PDW), and plateletcrit (PCT) utilizing a hematological analyzer. Data were analyzed using GraphPad Prism software.
Results: Platelet counts negatively correlated with PDW [r=-0.074, P=0.459; R=-0.023, P=0.815], MPV [r=-0.130, P=0.194; R=-0.081, P=0.417], and diastolic blood pressure [r= -0.023, P=0.818; R= -0.024, P=0.805]; and positively correlated with PCT [r= 0.103, P=0.308; R=0.143, P=0.155] and diastolic blood pressure [r=0.022, P=0.823; R= 0.008, P=0.932]. Moreover, PDW positively correlated with systolic blood pressure [r=0.105, P=0.298; R= 0.147, P=0.148] and diastolic blood pressure [r=0.146, P=0.145; R=0.173, P=0.084]. Based on Spearman but not Pearson correlation, PDW showed a negative correlation with PCT [r=-0.005, P=0.959; R=0.010, P=0.929].
Conclusion: The study shows a correlation between Plt count and indices in ischemic stroke patients. The research also presented evidence concerning the relationship between diastolic and systolic blood pressure and Plt counts and indices.

Abstract
Background: Diabetes Mellitus (DM) is a metabolic disorder whose pathophysiology has been linked to various genetic and environmental factors. The main mechanism of the development of complications has been implicated as inflammation-mediated. Various blood cell parameters are being used as early indicators of inflammation-mediated endothelial dysfunction; thereby predicting the severity or prognosis of DM. In this study, we aimed to evaluate the role of platelet-to-lymphocyte ratio (PLR) in predicting glycemic control in patients with DM.
Methods: This is a retrospective, hospital-based study conducted from August 2023 to December 2023. A total of 134 patients were included in the study. The hematological and biochemical reports of the study population were retrieved, and the data obtained was analyzed using SPSS software version 16.0.
Results: In this study, it has been found that PLR is significantly increased in patients suffering from DM with poor glycemic control compared to those patients with good glycemic control (P<0.001). In concordance with other studies, a positive association was observed between PLR and disease severity.
Conclusion: Based on the findings of the study, PLR may be used as a predictive marker in assessing the severity and prognosis of DM; however, the exact cut-off value is yet to be determined.

Abstract
Background: Post-operative wound infection has been a problem since surgery was started as a treatment modality and is the third most common cause of nosocomial infections with a reported incidence rate of 14-16%. This study aimed to investigate the prevalence, isolate and identify aerobic pathogenic bacteria from surgical site infections (SSI) and to determine the antibiotic susceptibility testing (AST) pattern of pathogenic bacteria.
Methods: This study was conducted at the Department of Microbiology SKIMS-Medical College, Bemina Srinagar, over a period of six months from November 2021 to April 2022. In the study, 210 samples from patients with SSI were included. Isolation, identification, and AST of the isolates were performed by standard microbiological techniques.
Results: Out of 210 SSI samples, 163 bacterial isolates were recovered and infection rate was more in 21-30 years age group (24.2%). Gram-negative bacteria were isolated in 50.4% (82/163) cases and E. coli was the most common organism (59.75%, 49/82). Gram-negative bacteria were sensitive to imipenem and none were resistant to polymyxin-B and colistin. E. coli was mostly resistant to cefoperazone, Acinetobacter and Klebsiella species were resistant to ceftazidime, Pseudomonas and Citrobacter were resistant to ceftriaxone. Gram-positive bacteria constituted 49.6% (81/163) and Methicillin-resistant Staphylococcus aureus (MRSA) was a frequently isolated species (66.6%, 54/81). MRSA- and methicillin-sensitive Staphylococcus aureus (MSSA) were mostly sensitive to amikacin, gentamycin, and tetracycline. Moreover, none of the Gram-positive isolates were resistant to linezolid, vancomycin, and teicoplanin. Enterococcus spp was mostly resistant to gentamycin.
Conclusion: This study developed an insight into post-operative wound infections and their incidence, organisms’ prevalence, and their antibiogram. Culture positivity in suspected cases of SSI was high (77.6%). MRSA and E. coli were frequently isolated from Gram-positive and Gram-negative bacteria.

Abstract
Background: Tumor necrosis factor alpha (TNFα) is a 17 kDa, an important soluble pro-inflammatory cytokine, which is involved in some tissue dysfunctions, including thyroid and liver tissue. In spite of its role in thyroid and tissue damage separately, the relationship between this factor and these two disorders has not been clarified. The aim of the present study was to evaluate liver biochemical parameters and TNFα in hypothyroid patients compared to euthyroid subjects.
Methods: To achieve this purpose, samples were transferred into tubes without anticoagulants and then centrifuged immediately to separate the serum. All markers in the serum were measured using commercial kits, including T3, T4, TSH, and TNFα, which were detected using the ELISA method. Liver function tests, including albumin, total bilirubin, and total protein were measured by spectroscopy and the colorimetric method, respectively. In addition, AST, ALT, ALP, and GGT were detected using enzymatic methods.
Results: Our results showed that the level of TNFα in hypothyroid patients was significantly higher than that in normal individuals (P = 0.009). TNFα had a significantly positive correlation with TSH and T3 but a negative correlation with T4. Furthermore, AST, ALT, and GGT had a positive correlation with TSH and a negative correlation with albumin, total protein, and total bilirubin. These correlations were insignificant (P < 0.05).
Conclusion: According to our data, the positive correlation of TSH with both TNFα and liver function tests may indicate a relationship between thyroid and liver function with each other.

Abstract
Background: The purpose of the present study was to investigate the effect of aerobic exercise and psilocybin after methamphetamine induction on the gene expression of certain cerebral cortex semaphorins in female Wistar rats.
Methods: In this experimental study, 40 female rats were placed into five groups: control (C), amphetamine (A), amphetamine-aerobic (AA), amphetamine-psilocybin (AP), and amphetamine-psilocybin-aerobic (AAP). Methamphetamine was injected at a dose of 15 mg/kg for 5 days in the morning. Psilocybin was administered at a dose of 1 mg/kg. The aerobic training program included running on a treadmill at 20–25 m/min, three days a week for eight weeks. After eight weeks, gene expression was measured using the Real-Time PCR method. The data were analyzed by one-way analysis of variance and Tukey's post hoc test at a significance level of P < 0.05.
Results: The results showed that the average gene expression of semaphorin 3A, semaphorin 4A, and semaphorin 7A in the cerebral cortex of the A group had a significant increase compared to the C group (P = 0.001). The AA, AP, and AAP groups showed a significant decrease in the average expression of semaphorin 3A and semaphorin 4A genes compared to the A group (P = 0.001). The AAP group had a significant decrease in the average expression of the semaphorin 3A gene compared to the AA and AP groups (P = 0.001). In addition, the AAP group showed a significant decrease in semaphorin 7A expression compared to the AP group (P = 0.007).
Conclusion: According to the results, aerobic training and psilocybin supplementation can help reduce semaphorin expression in the cerebral cortex of rats induced with methamphetamine.

Abstract
Background: Cervical cancer has seen a significant decline in death rates due to early diagnosis and treatment. The Pap test remains valuable but exhibits limitations, such as false positives and false negatives, with the former associated with atrophy-related changes. This article aims to bring attention to cervical carcinoma screening, focusing on the interpretation of atrophy-related changes in Pap smears and minimizing intervention.
Methods: This retrospective study, conducted at a tertiary care center, evaluated cases with intra-epithelial abnormalities or malignancies in Pap smears.
Results: A total of 11,680 cervical cytology smears received in the Department of Pathology, Vydehi Institute of Medical Sciences and Research Centre, Bengaluru, over 7.5 years (From January 1, 2016, to June 30, 2023), were reviewed. Of these, 56 cases exhibited epithelial abnormalities and were categorized as follows: 1. Atypical squamous cells of undetermined significance, 2. Low-grade squamous intraepithelial lesion, 3. High-grade squamous intraepithelial lesion, and 4. Malignancy. Among the 56 smears, 40 (71%) showed co-existent atrophy. Biopsies were available for 22 smears, and atrophy with epithelial abnormalities co-existed in 16 (28%) of these cases. Of these 16 cases, only eight (50%) were found to have abnormalities greater than Cervical Intraepithelial Neoplasia II dysplasia. This results in the positive predictive value of cervical cytology smears detecting epithelial abnormalities in cases with co-existing atrophy-related changes being only 50%.
Conclusion: The article emphasizes the importance of cautious interpretation of Pap smears in the presence of atrophy.

Abstract
Background: Enterobius vermicularis is the most important intestinal parasite in children worldwide. When this parasite migrates unexpectedly, the larvae move out of the intestine and enter organs such as the appendix, and can cause health risks.
Case presentation: An 8-year-old boy was admitted to the oncology clinic of Tabriz Children’s Hospital, complaining of fever of 39-40°C with abdominal pain, cramps, loss of appetite, weakness, and fatigue, associated with cervical lymphadenopathy, hepatomegaly, axillary mass, abdominal upper thigh, maculopapular rashes, and tiny petechiae on the chest and abdomen.
Results: On CT examination of the chest, moderate mediastinal and mesenteric lymphadenopathy was noted. The patient was hospitalized with a definitive diagnosis of acute lymphoblastic leukemia. On the seventh day of hospitalization, the patient developed additive colic pain (Contraction and cramping) around the umbilicus and concomitantly developed pain downward and rightward into the abdomen. Based on the clinical findings, the patient was thought to have acute appendicitis. Pathological examinations showed that E. vermicularis was the cause of the appendicitis.
Conclusion: The results of this study indicate that this parasite may be associated with inflammation of the appendix in patients with acute lymphoblastic leukemia. A screening program is still required in patients with immunodeficiency or those taking immunosuppressive drugs.

Abstract
Background: Hypertensive disorders, particularly preeclampsia (PE), complicate 2–8% of pregnancies and significantly contribute to maternal and perinatal mortality. PE disproportionately affects low-resource regions, accounting for 26% of maternal deaths in Latin America and 9% in Africa and Asia. Risk factors include extreme maternal age, chronic hypertension, obesity, diabetes, and racial disparities (Higher incidence in Black and Hispanic populations). The exact cause remains unclear, but angiogenic imbalance and immune dysregulation play key roles. This review focuses on the role of cytokines and chemokines in developing preeclampsia (PE).
Methods: A narrative review was conducted to examine studies on the immunological and vascular mechanisms of preeclampsia, with a focus on recent systematic reviews and high-impact research.
Results: The results highlighted a critical imbalance between pro-inflammatory (IL-6, TNF-α) and anti-inflammatory (IL-4, IL-10) cytokines in PE pathogenesis. Notably, reduced second-trimester IL-10 levels served as an early predictive biomarker. Endothelin-mediated vasoconstriction and Th1/Th2 immune imbalance further exacerbated endothelial dysfunction, a central feature of PE. While human and animal studies support these findings, precise mechanistic pathways remain elusive.
Conclusion: Cytokine and endothelin can serve as promising biomarkers and therapeutic targets for PE. Early IL-10 detection may improve risk prediction, but no causal links have been confirmed yet. Gaining a better understanding of these mediators could improve clinical strategies and help minimize complications. Future longitudinal research should focus on biomarkers and explore anti-inflammatory treatments for PE prevention.

Abstract
Background and objectives: Non-Hodgkin lymphoma represents a heterogenous group of lympho-proliferative malignancies with unique presentation and treatment response. This study was intended to assess the histomorphology of non-Hodgkin lymphoma subtypes and correlate with clinicopathological and immunohistochemical findings.
Methods: A retrospective study was conducted on all samples, diagnosed as non-Hodgkin lymphoma by histopathological analysis, with available immunohistochemical findings. Study was conducted in the department of pathology, for 24 months, during the period of March 2018 to February 2020. The specimens were fixed in 10 % formalin and representative sections were obtained.
Clinical details such as age, gender, location and presentation were recorded. Histopathological and immunohistochemical findings were correlated. Statistical analysis based on p value was performed.
Results: The study includes a total of 48 cases with a male predominance (56.3%). Cervical lymph node (35.4%) was the most common site. Extra nodal presentation was noted in 39.6% of the cases including stomach, testis, hard palate, para-sacral area and para-vertebral area. Diffuse large B-cell lymphoma (43.8%), followed by follicular lymphoma and mantle cell lymphoma were the most common subtypes. A statistically significant p value of 0.05 was obtained.
Conclusion: In our study, we found diffuse large B cell lymphoma (DLBCL) as the most common type of Non Hodgkin’s Lymphoma. Cervical lymph nodes were most common site of involvement. But involvement of sites like the testis and palate were also found, hence the probability of NHL in these rare sites should always to be considered.

Abstract
Introduction:
Dermatophytes are group of fungi that cause superficial infections via enzymes that degrade keratin in human skin, hair and nails. Several factors, including, gender, age, lifestyle, human migration, cultural habits, and socioeconomic status influence the prevalence of dermatophyte infections. Hot and humid climate in tropical and subtropical countries like India makes Dermatophytosis a very common superficial fungal infection.
Aim/objective:
To isolate & identify dermatophytes from clinically diagnosed cases of Dermatophytosis.
Methods:
Samples from 100 clinically diagnosed cases of Dermatophytosis were processed by KOH mount and fungal culture.
Results:
Out of 100 clinically diagnosed cases, Tinea corporis 42 (42%) was the commonest clinical type followed by Tinea cruris 25 (25%), Tinea unguium 21 (21%). Out of 100 samples, 53 were culture positive. Out of 53 dermatophytes isolated, T. rubrum 16 (30%) was the commonest followed by T. mentagrophytes 11 (20%) and T. violaceum 7 (13.3%). Out of 53
isolates, 49 (92.45%) dermatophytes were isolated on SDA and 51 (96.22%) dermatophytes were isolated from Dermatophyte test medium (DTM).
Conclusion:
Isolation and identification of etiological agents of Dermatophytosis is essential for the correct diagnosis as it is important to initiate appropriate treatment and also important for epidemiological purposes. Accurate assessment of the prevalence and etiological agents is desirable to estimate the size of therapeutic problem and prevent the transmission of such infection.

Abstract
Chronic basophilic leukemia (CBL) is a rare disorder and according to the published data, few cases have been reported as primary CBL. Morphologic findings in CBL, mostly mimic chronic eosinophilic leukemia and basophils have unusual and dysplastic morphology. A 47 years-old patient comes to the hospital with gastrointestinal symptoms and bloating. Complete blood count (CBC) showed leukocytosis and marked eosinophilia. After evaluating the PB smear, abnormal leukocytes with hypersegmented nuclei along with increase in eosinophils were observed. For further investigation patient was referred to hematology clinic and underwent bone marrow aspiration and biopsy. After the morphological examination, flow cytometry was performed on the aspiration sample to accurately diagnose the disease. Flow cytometric findings were in favor of CBL. Morphological findings is unreliable for basophils detection and for definite diagnosis, flow cytometry is reliable method to precise detection of basophils and CBL.

Abstract
Introduction: Bronchopulmonary lophomoniasis is an infrequent occurrence. In this study, we document a singular instance of pulmonary lophomoniasis exhibiting unconventional manifestations in Golestan province, Iran.
Case presentation: The case under examination pertains to a 47-year-old male inmate who has been encountering respiratory issues for a duration of four months, culminating in a diagnosis of lophomoniasis. Both blood and sputum cultures yielded negative results. Similarly, bronchoalveolar lavage tests for bacterial and fungal pathogens returned negative findings. However, bronchoalveolar lavage (BAL) results (microscopic) showed mild positive lophomoniasis targeting Lophomonas blattarum and Serum IgE=387 was relatively higher than normal limits.
Conclusion: The patient received treatment with metronidazole, leading to the resolution of all clinical complications within a span of four weeks.
