The longest period to recurrence of granulosa cell ovarian tumor: 41 years after initial diagnosis

Abstract

Granulosa cell tumors (GCTs) are characterized by slow growth, local spread, and late recurrence. The authors report the case unique for both unusually large dimensions of the recurring tumor and the fact that it was confined only to the omentum, where it has recurred 41 years after the initial surgery including salpingo-oophorectomy. This is the longest reported period from initial diagnosis to the recurrence of GCT. This case report is important as it proves that recurrence of GCT is possible even after an extremely long period of time after the initial surgery, due to the nature of this tumor, and the inhibition of apoptosis process. © 2018 S.O.G.
