Immunohistochemical analysis of cytochromes P-450 aromatase and P-450 17α-hydroxylase, which catalyze the production of estrogens and androgens, respectively, was performed for 23 cases of ovarian Brenner tumor. Immunoreactivity for P-450 aromatase was observed in the epithelial cells of the tumor distinctly in two cases and faintly in four cases, while immunoreactivity for P-450 17α-hydroxylase was seen in two cases. No immunoreactivity was observed in the stromal cells of the tumors, nor were luteinized cells observed in the cases examined. No correlation was observed between the immunoreactivity of cytochromes P-450 in the epithelial cells of the tumor and endometrial abnormalities. These findings, together with a review of the literature, suggest that the usual Brenner tumor is not associated with specific steroidogenesis. Rare massive Brenner tumors may, however, be capable of androgenic or estrogenic activity.
