Adult granulosa cell tumour is rarely encountered in adolescents. Tumours in their early stages have a favourable prognosis whereas those in advanced stages have a poor outcome. Documented series of tumours at advanced stages are very rare and follow-up is difficult because of the frequently prolonged intervals before progression of the tumour. That may explain why it is very difficult to define a consensual management strategy with or without adjuvant therapy such as chemotherapy or radiation therapy. We describe a case of adult granulosa cell tumour in a 14-year-old girl who initially underwent laparoscopy for an “unsuspicious” cyst. Management was then modified according to oncological guidelines because of the histological nature of this cyst.
