Endometrial adenocarcinoma presenting as an isolated calcaneal metastasis. A rare entity with good prognosis

A 59-year-old woman presented with progressive pain, swelling, and erythema of her right foot. Biopsy of a destructive calcaneal lesion revealed a metastatic adenoacanthoma with focal adenosquamous carcinoma consistent with an endometrial origin. This was confirmed on hysterectomy. Postoperative treatment consisted of systemic chemotherapy, hormonal therapy, and local radiotherapy to the foot. She has now experienced 5 years of complete remission. This is a case of an endometrial adenocarcinoma presenting as an isolated calcaneal metastasis with an excellent outcome.
