Adult granulosa cell tumor is often a hormonally active stromal cell neoplasm of the ovary with malignant potential. Intra-operative pathological assessment is a valuable tool in guiding optimal surgical treatment in patients. Of the various intra-operative cytological diagnostic modalities, scrape smear cytology is an effective, economical, simple, fast and reliable method with results comparable with frozen section diagnosis. We describe a case of adult granulosa cell tumor in a 30-years-old lady diagnosed on intra-operative scrape cytology, and further reconfirmed on frozen section and histopathology.
