title: Ovarian juvenile granulosa cell tumor associated with Maffucci's syndrome.
abstract: A 15-year-old girl developed a juvenile granulosa cell tumor associated with Maffucci's syndrome (enchondromatosis + hemangiomas). Clinical manifestations of the disease included an abdominal mass and progressive anemia. She underwent the removal of a Stage Ic juvenile granulosa cell tumor and subsequent adjuvant chemotherapy. On follow-up examination 4 years later, no recurrence of the ovarian tumor was noted. A review of the literature showed 10 previous cases of juvenile granulosa cell tumor associated with enchondromatosis, two associated with Maffucci's syndrome, and the rest with Ollier's disease (enchondromatosis). Ovarian juvenile granulosa cell tumor may occur not infrequently in female patients with enchondromatosis in the first or second decades, in contrast to the widely recognized sarcomatous changes of enchondromas that usually occur after the second decade. Data provided from these cases also emphasize the concept of a generalized mesodermal dysplasia.
