Poroid Hidradenocarcinoma of the Ankle: Case Report of a Rare Malignant Cutaneous Adnexal Neoplasm

Abstract

Soft-tissue masses on the anterior ankle result from a broad range of underlying processes, often presenting a diagnostic challenge. Appropriate treatment of these tumors can be determined by using a combination of patient history, interpretation of pathologic findings, physical examination, and radiographic appearance. We present a case of an exceptionally rare malignant cutaneous adnexal tumor, highlighting the importance of adherence to fundamental biopsy principles for diagnosing and managing musculoskeletal lesions.
