title: Bilateral juvenile granulosa cell tumors in a 4-month-old dysmorphic infant. A clinical, histologic, and ultrastructural study.
abstract: Juvenile granulosa cell tumors were encountered within bilateral cystic ovarian masses in a 4-month-old infant. The child was the product of a consanguinous pregnancy, and manifested poor growth, relative microcephaly, facial asymmetry, and a malformed left ear. There was no history of gestational drug or hormone ingestion, and no evidence of abnormal endocrine activity after birth, however, the serum alpha-fetoprotein level was mildly elevated. The tumors were well defined by sonography and there was no evidence of metastasis. Histologically, a dense proliferation of round to oval tumor cells showed considerable individual cell necrosis and frequent microcyst formation. There was no evidence of luteinization and only mild nuclear pleomorphism. Immunoperoxidase study failed to reveal alpha-fetoprotein. Ultrastructural study supported the granulosa cell nature of the tumor, but a few cells contained bundles of intracytoplasmic filaments. There has been no evidence of recurrent disease during a 16-month follow-up period, and serial alpha-fetoprotein determinations have remained in the reference range. Comparison with two previously reported bilateral juvenile granulosa cell tumors suggests that this tumor occurs in young infants, and is amenable to conservative therapy.
