A Giant Extraskeletal Chondroma of the Foot: A Case Report

Chondromas and osteochondromas are common benign bone tumors frequently located in the small bones of hands and feet. Extraskeletal chondromas are much rarer and are exceptional if their size exceeds 3 cm.

We report an exceptional case of a giant extraskeletal chondroma of the foot in a 71-year-old man who presented to our outpatient department with a huge mass of the dorsal side of the right foot.

The clinical aspect and the magnetic resonance imaging where suggestive of giant cell tumor of tendon sheath. After a wide surgical excision was performed, the pre-operative findings and histological study suggested otherwise.

Through this case report we discuss the diagnosis issues and the treatment options of extraskeletal chondromas.
