Abstract:
Primary trabecular carcinoid of the ovary is very rare and less than 30 cases have been reported. Herein is reported a primary trabecular carcinoid of the ovary which contained an epidermoid cyst in a 80-year-old woman. Gross examination showed 12 x 11 x 7 cm- sized mass in the right ovary. On cut-surface, the mass was composed of multilocular cyst containing serous and keratinized material and of 5 x 3.5 cm-sized solid area with extensive necrosis and hemorrhage. Microscopic examination revealed that the tumor cells are almost arranged in trabeculae and focally in insular pattern. Also, the tumor contained an epidermoid cyst but not other teratomatous elements. Tumor cells were immunoreactive for cytokeratin, neuron specific enolase (NSE) and chromogranin. Electron microscopic tindings revealed characteristic, round-shaped neurosecretory granules and perinuclear microfilaments.
