RESUMO
Background and Aims: Cholelithiasis is known to produce diverse histopathological changes in the gallbladder mucosa. In the present study, we aimed to find the correlation between various gallstone characteristics (i.e., number, size, and morphological type) with the type of mucosal response in gallbladder mucosa (i.e., inflammation, hyperplasia, metaplasia, and carcinoma). Methods: The present study was conducted prospectively on 100 patients undergoing cholecystectomy for symptomatic cholecystitis. Gallstones were assessed for various parameters, i.e., number, size, and morphological type. Gallbladder mucosa was subjected to histopathological examination. Sections were taken from body, fundus, and neck of gallbladder. Results: Of 100 cases, maximum type was of mixed stones (54%) and was multiple in number (46%). However, gallstone type and number are nonsignificant variables to produce precancerous lesions (i.e., hyperplasia and metaplasia). Statistically significant results were obtained while comparing the mucosal response with gallstone size (P = 0.012). Conclusion: As the gallstone size increases, the response in gallbladder mucosa changes from cholecystitis, hyperplasia, and metaplasia to carcinoma. Gallstone type and number are nonsignificant variables to produce precancerous lesions

Background: Breast malignancies encompass various subtypes which differ in their clinical presentations, outcomes, and response to the treatment regimens. Thus, a proper histological diagnosis and a special mention of the rare histologic subtypes are required to formulate clear recommendations of their treatment protocols. Materials and Methods: This is a 1-year retrospective study highlighting the rarely encountered subtypes on the mastectomy specimens received. Results: We encountered only 11 rare cases out of the total 153 mastectomy specimens received. The rare subtypes were as follows mucinous cystadenocarcinoma (0.6%), mucinous carcinoma (0.6%), dermatofibrosarcoma protuberans (0.6%), Squamous cell carcinoma (0.6%), papillary carcinoma (2.6%), medullary carcinoma (0.6%), and malignant mesenchymal tumor (1.3%). Conclusion: Our data suggest that these variants are distinct clinicopathological entities with a unique hormonal receptor status. Scant information is available on the rare breast tumor subtypes
