Primary Ewing’s sarcoma of the temporal bone: a rare entity and review of the literature

Abstract

Ewing’s sarcoma (ES) is the second most common malignant primary bone tumour in children and adolescents. It primarily affects the diaphysis of long bones and pelvis. ES arising from temporal bone is extremely rare. To date, 43 such cases have been described in the literature. Clinical and radiological features are non-specific. Diagnosis is based mainly on immunohistochemistry. The present article presents an extremely rare case of ES of the temporal bone in a 20-year young man, and he was successfully treated with multiagent chemotherapy and radiotherapy.
