Congenital intra-abdominal bilateral juvenile granulosa cell tumors of the testis associated with constitutional loss of material from chromosome 4.
Juvenile granulosa cell tumor (JGCT) is an uncommon gonadal stromal tumor that occurs rarely in the testis. We report a newborn boy with bilateral intra-abdominal JGCT presenting with abdominal distention and respiratory distress at birth. He was taken to the operating room emergently, and 2 large masses connected by gubernacula to the inguinal canals were resected. Associated abnormalities included a constitutional chromosome 4 abnormality, polymicrogyria, and renal cysts. This report describes a rare presentation of JGCT with abdominal compression and expands the literature to include bilateral testicular involvement. Additionally, it is the 1st report of JGCT associated with a chromosome 4 abnormality, highlighting a genetic region that may be important in JGCT development.
