title: Metastatic calcaneal lesion associated with uterine carcinosarcoma.
abstract: Metastatic lesions of uterine carcinosarcoma most commonly occur in the abdomen and lungs and less frequently in highly vascularized bone. We report a rare case of an 86-year-old female with uterine carcinosarcoma with metastasis to the left calcaneus. The patient had a history of uterine carcinosarcoma with hysterectomy and bilateral salpingo-oophorectomy, along with bilateral pelvic and aortic lymphadenectomy, with no adjuvant therapy. The initial pedal complaint was that of left foot pain. The initial radiographic findings were negative; however, magnetic resonance imaging scans revealed a substantial area of marrow edema in the calcaneus. An excisional biopsy was performed, and histopathologic analysis revealed adenocarcinoma with features consistent with the patient's previous uterine tumor specimen. The patient was given one treatment of chemotherapy and was discharged to a hospice, where she died of her disease 2 weeks later.
