Chondroma of the subcutaneous bursa of the Achilles tendon.

Abstract

A 46-year-old female presented a six-month history of posterior heel pain. Clinical and radiographical examination revealed a nodular calcified mass into the subcutaneous tissue of the Achilles tendon bursa. Following excision, histopathology showed an extraskeletal soft-tissue chondroma. Follow up at 24 months showed no recurrence. To our knowledge, this is the first description of a soft tissue chondroma at this site: some soft tissue tumors develop at unusual anatomic location.
