Abstract

Müllerian adenosarcoma with sarcomatous overgrowth presented by a 52-year-old female patient after adjuvant tamoxifen treatment for breast carcinoma is described. The diagnosis was made on histological basis after curettage and complementary total hysterectomy with bilateral salpingo-oophorectomy. The immunohistochemical study showed high expression of estrogen receptors in the epithelial component of the lesion and irregularly positive findings in the stroma. The proliferative activity evaluated by Ki-67 immunoexpression was higher in the stroma than the epithelium. Some of the stromal cells showed rhabdomyoblastic differentiation. The association of tamoxifen use and development of mesenchymal neoplasms is discussed.
