Abstract
Granulosa-cell tumors of 4 cases and theca-cell tumor of one case were pathologically investigated. Two cases of granulosa-cell tumor represented folliculoid type, forming folliculoids resembled to follicles of an ovary. On the other hand, parenchymatous type of two cases was composed of the cells with atypical characters, and revealed no obvious folliculoid structures. One case of them represented metastatic lesions in many organs. Theca-cell tumor was composed of atypical cells showing various cellular arrangements. Metastaic lesions were also noted. Ultrastructurally, granulosa-cell-tumor cells of folliculoid type contained well-developed rough-surfaced endoplasmic reticulums and Golgi-complex remarkably. Concentric lamellar bodies, fat droplets and fine filaments were also noticeable.
