Postpartum Juvenile Granulosa Cell Tumor: A Case Report

Abstract

Granulosa Cell Tumors (GCTs) are extremely rare, sex cord-stromal tumors constituting only 1% to 2% of all ovarian malignancies. On the basis of age of onset and pathohistological characteristics, these tumors are subdivided into two distinct forms, the adult type (AGCT) and the juvenile type (JGCT), representing 95% and 5% of the tumors, respectively. Compared to the adult type, which is more common in the fifth decade, JGCT is rarely seen and the majority (90%) is reported in prepubertal individuals or those aged less than 30 years. We report an interesting case of a 24-years old woman with enormous ovarian juvenile granulosa cell tumor of the right ovary. Considering all the anamnestic data and ultrasound reports before and during the first pregnancy, where there has been no evidence for the presence of any tumor, we came to conclusion that the tumor grew rapidly during the first year since delivery. Maybe the tumor was present during the pregnancy or even before, but most probably it was not noticed because it small initial size or it was masked by the growing uterus at ultrasound. The first data for the tumor existence is 3 months before the surgical treatment.
