Extraosseous Osteosarcoma in Ibadan: Case Series over a 20-Year Period

Abstract

Extraosseous osteosarcoma (EOO) is a rare form of sarcoma. There have been few reports of cases and outcome from an African population.Out of 112 cases of sarcomas seen at the UCH, Ibadan between 1986-2005, 5 were EOO. All presented late on account of initial excision without histology and outcomes were poor. EOO occurs in the black population of Sub-Saharan Africa. The outlook for these patients is still bleak.
