BACKGROUND Thyroid cancer is the most common malignant endocrine cancer worldwide. The diagnosis and distinction between benign and malignant thyroid neoplasm, especially in follicular patterned thyroid lesions is still difficult. Of the various immuno histochemical markers, Galectin-3 was most reliable in diagnosis of thyroid carcinoma. AIM To study diagnostic utility of Galectin-3 in thyroid neoplasm. METHODS This was laboratory based diagnostic study, where 92 cases of thyroid neoplasm (48-malignant and 44 benign) were analyzed for Galectin-3 expression. The Galectin-3 staining was quantitatively evaluated as percentage of positive tumor cells and qualitatively for intensity of staining. When membrane ± cytoplasmic immunoreactivity of Galectin-3 was present in more than 10% of tumor cells was considered as positive staining. RESULTS Galectin 3 expression was significantly higher in thyroid cancer as compared to benign thyroid neoplasm (p<0.001). 33/35 cases of PTC were positive for Galectin-3 expression. Galectin-3 expression was significantly higher in FTC as compared to FA (p <0.01). Galectin-3 was also useful to differentiate between FVPTC and FTC (p<0.01) and FVPTC from other benign neoplasm (<0.01).The sensitivity, specificity, positive predictive value and negative predictive value in differentiating benign and malignant thyroid neoplasm were 83.33%, 100%,100%, 84.62% respectively. CONCLUSION Galectin-3 is a potential marker in differentiating benign and malignant thyroid neoplasm. It can used as sole marker for differentiating PTC and benign thyroid neoplasm and also useful to differentiate between FVPTC and FTC. [ABSTRACT FROM AUTHOR]

Background: Leprosy is an ancient, chronic granulomatous infectious disease caused by Mycobacterium leprae, principally affecting the skin and peripheral nerves. The clinical manifestations of leprosy are variable and can mimic a variety of other skin diseases. Thus, histopathological examination plays an important role in early diagnosis and management. Aim: The aim was to study the clinicohistopathological correlation of all suspected cases of Hansen's disease. Materials and Methods: A retrospective study was conducted on 207 skin biopsies obtained from patients clinically diagnosed as new lesion of leprosy in the department of pathology from 2016 to 2019. Demographic, clinical details of the patients were retrieved from hospital information system. Hematoxylin–eosin- and Fite–Faraco-stained sections were evaluated for features confirming leprosy and further categorized as per Ridley–Jopling system. Sensitivity, specificity, and concordance rates were studied. Results: The male-to-female ratio was 1.5:1. The agreement between histopathological and clinical diagnoses was more than 90% in all the subclasses except for borderline tuberculoid leprosy (BT) and tuberculoid leprosy (TT) which showed an agreement of 86.5% and 88.4%, respectively. The sensitivity of clinical diagnosis ranged from 69.70% for indeterminate to 100% for histoid and neuritic types. The specificity ranged from 90% for BT and TT to 100% for neuritic leprosy. Conclusion: Clinical diagnosis of early leprosy lesions offers difficulties even to experienced dermatologists as a patient presents in different clinicopathological forms, depending on host immune status. Thus, the correlation between clinical, histopathological, and bacteriological features is required for diagnosis and classification of leprosy. Nerve damage is irreversible; therefore, early detection and treatment is important to prevent Grade 2 disabilities. [ABSTRACT FROM AUTHOR]

Background: Endometrial carcinoma (EC) is the only gynecologic cancer with increasing incidence and mortality worldwide. This study aimed to determine association of cell proliferation marker CyclinD1, p53 and Ki67 with clinicopathological parameters and survival analysis in patients of EC., Material and Methods: One hundred twenty-four histological confirmed cases of EC treated at our institute were included in this study. The appropriate tissue blocks of cases which were retrieved from 2010 to 2015. The study period was from Jan 2018 to Jan 2020. Data pertaining to patient's clinical details, histopathological diagnosis, treatment and follow up was retrieved from Hospital information System. Immunohistochemical evaluation of Cyclin D1, p53 and Ki67 was done. Overall survival and Disease-free survival for each category were analyzed by the Kaplan-Meier method., Results: Of the 124 cases of EC, 108(87.09%) cases were of type I and 16 (12.89%) cases of type II. Overall positive staining of cyclinD1, p53 and Ki67 were noted in 53.22%, 42.22% and 32.3% cases respectively. The clinicopathological parameters affecting disease-free survival were age (p=0.039) histological types (p=0.007), and FIGO stage (p< 0.001). Elevated Ki67 index and p53 overexpression was associated with type II morphology (p= 0.001). Whereas Cyclin D1 expression was associated with type I morphology and poorly differentiated tumor., Conclusion: Cyclin D1 positive staining, p53overexpression and an elevated Ki-67index all had an independent prognostic significance in endometrial cancer. This panel of biomarkers may help to differentiate tumor behavior, and necessity for more radical surgery and post- operative chemotherapy.
