title: [Sclerosing stromal tumor of the ovary].
abstract: A 20-year-old woman had the complaints of a tumor in the lower abdominal region and irregular menstruation. A spherical tumor measuring 7 X 6 X 3.5 cm in the great dimension was removed from the left ovary. The cut surface showed a lobular pattern and cystic degeneration in some areas. Histological examination revealed edematous areas and highly cellular areas. The cells were variable in size and shape. Round cells resembled signet-ring cells in places. By PAS reaction and alcian blue stain, these cells were found to be negative, but by Sudan III stain, positive. Postoperatively, the patient complained of genital bleeding for five days. Subsequently, her menstrual pattern returned to normal.
