Isolated talus metastasis from breast carcinoma: a case report and review of the literature.

BACKGROUND: Acrometastases are very rare and have been identified in only a few cases on the foot. At the onset, they might be misdiagnosed as arthritis. CASE REPORT: A 59-year-old woman with isolated metastasis to the talus, originating from breast carcinoma was treated by radiotherapy, letrazole, and intravenous bisphosphonates. RESULTS: The review of the literature revealed that this is the first case of an isolated metastasis to the bone of talus from a breast carcinoma, while there are a few cases originating from other organs. The differential diagnosis of acrometastases may be difficult. CONCLUSION: Pain in the foot or hand of a patient with a known history of malignancy should be considered as potential metastasis.
