Female adnexal tumor of probable Wolffian origin: evidence of a low grade malignancy. 
A broad ligament tumor with the histologic features of a female adnexal tumor of probable Wolffian origin, as described by Kariminejad and Scully, is reported.  Although previous cases were thought to be benign, in the present case, hepatic metastasis occurred 6 years after resection of the primary.  Cytologic features by light microscopy were more anaplastic than in the original cases.  Ultrastructural findings were not specific for any normal adult or fetal mesonephric tissue previously studied by electron microscopy.
