title: Virilizing ovarian tumor of low malignant potential associated with antecedent tamoxifen use for breast cancer.
abstract: A patient is described who was treated with tamoxifen for breast cancer and developed an androgen-producing ovarian tumor of low malignant potential, which itself is a rare condition. Clinically overt virilism was leading to the diagnosis and promptly improved after surgical removal of the tumor. A causal relationship between tamoxifen use and the tumor is discussed on the basis of the known tumor-inducing potential of tamoxifen.
