The aim of the study was to evaluate the frequency and patterns of histopathologically diagnosed germ cell ovarian tumours of cases attending a tertiary level medical facility based hospital in Guwahati,Assam,India. Total of 102 cases of ovarian tumours were studied out of which 31 cases were germ cell tumors. Abdominal mass was the most predominant clinical presentation. The cases were investigated and surgically treated. The formalin 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 . In germ cell tumours, benign cystic teratomas constituted highest numbers (26.47%), followed by dysgerminoma(1.96% ),Immature teratoma(0.98%) and Yolk sac tumor(0.98%).
