Primary ovarian rhabdomyosarcoma with heterologous elements: a case report.

Primary ovarian rhabdomyosarcoma with heterologous elements is a rare ovarian neoplasm. Most cases reported in the English literature were associated either with teratomas or with mixed mullerian tumors. Pure primary rhabdomyosarcoma is extremely uncommon. We present hereby a case of primary pure embryonal rhabdomyosarcoma in a 25-year-old woman, showing heterologous elements, but associated neither with teratoma nor with mixed mullerian tumors.
