Ewing Sarcoma of Calcaneum Masquerading as Chronic Heel Pain

Chronic heel pain is a common disabling clinical condition that may be caused by a spectrum of osseous or soft-tissue disorders. Calcaneal tumors, although rare, may cause debilitating heel pain. Ewing’s sarcoma being one such cause is the second most common primary malignant tumor of bone. The most common primary bony sites include the long bones, pelvis, chest wall, and spine. However, it is responsible for only 3% to 5% of cases in bones of the hands and feet. This case was a 14-year-old boy, who attended our clinic with complaints of right heel pain and swelling for 6 months after sustaining a fall. Radiography showed a sclerotic lesion in the calcaneum. He underwent fine needle aspiration cytology and was diagnosed with Ewing’s sarcoma. He was treated with chemotherapy followed by below-knee amputation. This study aims to present an anatomical rare case of Ewing’s sarcoma as preliminary diagnosis masquerading as chronic heel pain.
