Abstract
Juvenile granulosa cell ovarian tumor is a rare cause ofpseudo-precociouspuberty. We report a case of a 6-year-old female with neurofibromatosis type 1 (NF1), associated with pseudo-precocious puberty (PPP). A thorough workup revealed a large multi-cystic right ovarian mass, which turned out to be a juvenile granulosa cell tumor (JGCT). This report documented a rare case of PPP caused by JGCT in a child with NF1. Verbal consent was taken from the family.
