Background:An adnexal mass refers to a lump or growth located near the uterus, typically in the ovaries, fallopian tubes, or surrounding tissues.The present study was conducted to assess the histopathological pattern of adnexal masses. Materials & Methods:48 adnexal masses received in the department of Pathology were recruited for the study. Specimens were labelled. Gross examination was done and the tissue was preserved in 10% formalin immediately. After fixation of the tissue for 24-48 hours, it was sectioned and processed for microscopy. Slides were stained with Hematoxylin and Eosin stain. Results: age group 20-40 years had 5, 40-60 years had 30 and >60 years had 13 patients. Histology of adnexal masses showed inflammatory lesions in 3, ectopic gestation in 10, non- neoplastic cyst in 2, surface epithelial lesion in 22, germ cell tumor in 8, metastatic malignancyin 2, and sex cord stromal tumor in 1 case. Symptoms were menstrual irregularities in 19, pain in 35, and abdominal masses in 21 patients. Ovarian neoplasm was benign in 25, borderline in 5 and malignant in 3 cases. The difference was significant (P< 0.05). Conclusion: A common diagnostic challenge for the treating physician is an adnexal mass. Patients in the reproductive age group frequently have adnexal masses as a result of ectopic pregnancies. Another important factor contributing to adnexal mass is ovarian neoplasm.
