A 23‐year‐old woman underwent resection of a tumorous right ovary after long‐standing irregular genital bleeding. The tumor measured 50X30 mm and had a yellowish‐white solid cut surface with scattered small cysts. The light microscopic diagnosis was a sex cord tumor with annular tubules. Ultrastructurally, the tumor cells had Charcot‐Boettcher filaments and showed vimentin positivity by immunohistochemistry. A three‐dimensional reconstruction study proved that the tumor cell nests had an ovoid outer margin and contained blind‐ended ellipsoid hyaline bodies. This tumor is presumed to be a variant of sex cord/stromal tumor showing differentiation predominantly to Sertoli cells. Acta Pathol Jpn 41: 701–706, 1991.
