Abstract
-
Juvenile granulosa cell tumor is rare but one of the common congenital testicular
neoplasms. Although histological features are typical of its ovarian counterpart, testicular
juvenile granulosa cell tumor has a distinctly different clinical presentation. We report a
case of juvenile granulosa cell tumor arising in the cryptochid testis of a 4-day-old
newborn. A 6 5 5 cm sized multilocular cyst containing thick, mucinous fluid was
found in the peritoneal cavity. The external surface of the cyst was smooth and the
septae were relatively thin. The cyst consisted of numerous mucin-filled, cystic follicles
lined by cells having vacuolated cytoplasm and round to oval dark nuclei without
grooves. Cells resembling granulosa cells of an ovarian follicle were also observed in the
intervening stroma forming irregular solid nests.
