The prevalence of non-neoplastic and neoplastic lesions varies from region to region. Fine Needle Aspiration Cytology (FNAC) is a rapid, minimally invasive, reliable and relatively simple diagnostic method. We wanted to study the frequencies of different lesions in FNAC of breast lump in our region and to observe cyto-histological correlation wherever possible. METHODS A two years prospective study was carried out in the department of pathology, RIMS, Imphal during the period January 2016-December 2017. A total of 434 cases of breast lesions were encountered during this period. RESULTS Of the total 434 cases infectious/inflammatory lesions were 100 (23.1%), benign 268 (61.7%), malignant 40 (9.2%), suspicious for malignancy 02 (0.5%), unsatisfactory 18 (4.1%), and others 6 (1.4%). The most frequent infectious/inflammatory lesion was acute mastitis in 50 (11.5%) followed by sub-areolar abscess in 17 (3.9%) and fat necrosis in 17 (3.9%). Fibroadenoma in 142 (32.7%) cases was the most common benign breast lesion followed by benign proliferative breast lesion without atypia 14 (22.1%). Among the malignant, 39 (9%) cases were carcinoma and one case (0.2%) was lymphoma. Mean age of presentation was 32.82 years. Most commonly involved age group was 21-30 years and right breast was more commonly involved. Cytohistological correlation was done in 41 cases and 35 benign and 6 malignant cases diagnosed cytologically were confirmed by histology, though there were cases with variable diagnosis. So, in differenting benign from malignant lesions, the sensitivity, specificity, positive predictive value, negative predictive value was 100%.
Corroboration of Fine Needle Aspiration Cytology Findings with Cell Block Study of Malignant Lung Lesions Using Immunostains (TTF1, Napsin A, P40 and Chromogranin A)

FNAC alone has its limitations in sub categorization of lung malignancy because of lack of architecture. Cell block preparation from FNAC material with immunohistochemistry panel would supplement the FNAC nding. Objectives: To determine the utility of cell block study using immunostains (TTF 1, Napsin A, p40 and Chromogranin A) in corroborating the ndings of FNAC in the study of malignant lung lesions. Materials and methods: A hospital based cross sectional study was done on the FNAC sample from lung masses followed by cell block study and immunohistochemical staining for (CHROMOGRANIN A, NAPSIN A, p40, TTF1). Data was analyzed using IBM SPSS statistics version 21 Software. Results: A total of 32 (54.2%) cases were found malignant and 27 (47.3%) cases were found benign. A total 59 cell block were prepared from 32 cases positive for malignancy (PFM...
