Ewing's sarcoma of scapula: a rare entity.

Ewing's sarcoma is the second most common malignant bone tumour of childhood and adolescence. It may affect any bone, but it is frequent in the femur, ilium and the tibia. Here the authors are reporting a case of Ewing's sarcoma involving scapula in a 14-year-old boy presenting with pain and swelling around the shoulder. Swelling was removed which on histopathological examination showed solid sheets closely packed, poorly differentiated small cells that have a high nuclear-cytoplasmic ratio, fine chromatin and small nucleoli. A tentative diagnosis of Ewing's sarcoma was made which was confirmed by immunohistochemistry.
