Abstract

A total of 102 cases of ovarian tumours were studied with aim to evaluate the frequency of histopathologically diagnosed ovarian tumor cases attending a tertiary level medical facility based hospital in Guwahati. Abdominal mass was the most predominant clinical presentation. The cases were investigated and surgically treated. The formalein fixed specimens ( simple oophorectomy or hysterectomy with unilateral /bilateral salpingo-oophorectomy) were examined grossly ,processed routinely and the sections were stained with H& E stain. The microscopic findings were noted and interpreted according to WHO classification of ovarian tumour. Surface epithelial tumour was the commonest tumour according to the histogenesis followed by germ cell tumour. Among the malignant surface epithelial tumours, the incidence of mucinous cystandencarcinoma was 6.86% and serous cystadenocarcinoma was 2.94% . Serous cyst adenoma was the commones tumour in benign category. In germ cell tumour category, benign cystic teratomas constituted highest numbers (26.47%), followed by dysgerminoma(1.96%). Six cases of sex cord stromal tumour ( 4 cases of granulosa cell tumour & 2 cases of Sertoli Leydig cell tumour) and 2 cases of kruckenberg tumour were also detected in the study.
