An ovarian tumor of probable Wolffian origin with hormonal function.

In 1973, the histopathologic features of nine neoplasms with a distinctive appearance were reported under the term "female adnexal tumor of probable Wolffian origin." Although to date more than 40 cases of this disease have been reported in the literature, there have been only a few reports that the tumors might be endocrinologically active. We report on a hormonally active tumor of this type.
