Abstract
A 55-year-old woman had a history of prolonged vaginal bleeding. Dilatation and curettage confirmed poorly differentiated endometrial adenocarcinoma. After hysterectomy, salpingo-oophorectomy, and 5,040 cGy of postoperative irradiation, lung metastases developed, which temporarily responded to chemotherapy that included adriamycin and cisplatin. Metastatic lesions developed later in the left acetabulum and the hallux. The latter, clinically reminiscent of pyogenic granuloma, affected only skin. The poorly differentiated toe metastasis duplicated areas of the primary endometrial adenocarcinoma and was immunohistochemically similar to it. While appearing quite rarely, and generally late in the disease, pedal skin lesions may represent metastases from known or occult visceral cancers.
