A 53-year-old man presented to the orthopedic outpatient clinic with pain and swelling in the right heel without any trauma. On physical examination and radiologic assessment, a lesion with calcification and peripheral sclerosis was detected in the medullary cavity of the calcaneus, and computed tomographic images revealed cortical thinning adjacent to the lesion. Magnetic resonance images showed a 23 × 19-mm lesion. Tru-Cut biopsy, performed to clarify the diagnosis, revealed an enchondroma. As a definitive treatment, curettage of the lesion and grafting of the cavity was performed. Although enchondromas are common pathologic abnormalities of the skeleton and are usually asymptomatic, atypical localization, such as the calcaneus, and atypical clinical manifestations, such as heel pain, should also be kept in mind.
