Metastatic Pulmonary Adenocarcinoma of the Talus: A Case Report.

Abstract

Tumors rarely metastasize to the foot bones; however, a misdiagnosis can lead to a poor outcome. These metastatic tumors can cause foot pain and other symptoms in patients who are asymptomatic for the primary tumor. To accurately diagnose acrometastases, the attending physician must have a high index of suspicion and conduct a thorough examination and appropriate diagnostic testing. We present a rare case of metastatic pulmonary adenocarcinoma of the talus, which was initially misdiagnosed as a benign bone cyst. After pulmonary adenocarcinoma was diagnosed, the patient received multidrug treatment for the primary and metastatic lesions and was still responding well at the 12-month follow-up visit.
