Sclerosing stromal tumor of the ovary (SST) is a rare, benign neoplasm in young women. Three cases of SST are studied for immunohistochemical detection of hormone and hormone synthetic enzymes. The SST Case 1 was a 61 years old, Case 2, 19 years old and Case 3, 27 years old. All three women were Japanese. Immunohistochemical studies of Cases 1 and 2 showed that tumor cells were positive for P-450 side chain cleavage, 3β-hydroxysteroid dehydrogenase. P-450 17α-hydroxylase and lyase. In Case 1, tumor cells were negative for P-450 aromatase, but they were positive in Case 2. These findings suggested the production of E2 precursors by tumor cells. Immunostain for E revealed some reactivity in tumor cells in Cases 1 and 3, but not in Case 2. The collective evidence indicates that some SST cells produce sex steroid hormone.
