Ewing's Sarcoma of the Finger.

Ewing's sarcoma is a mesenchymal cell tumor usually seen in long bones but very rarely seen in the bones of a finger. Swelling and pain are the most common complaints of the affected finger. In radiological imaging, it may be seen as permeative bone destruction accompanied by a soft tissue component or an expansile bone lesion. A 27-year-old right-hand dominant female patient presented with a swelling on the proximal phalanx of her right 3(rd) finger that had existed for 3 years. However, the mass started to gradually increase in size and the pain worsened over a period of 5 weeks. The mass was excised under regional intravenous anesthesia and Ewing's sarcoma was confirmed following a histopathological evaluation. No local recurrence or metastasis was detected 1 year after surgery. Since Ewing's sarcoma is rarely seen in the finger, we present this case with its radiological and clinical findings.
