Abstract

Extraskeletal osteosarcoma (ESOS) is an aggressive malignant tumour, producing neoplastic osteoid without attachment to the bone or periosteum. It can occur anywhere in the body including soft tissue, mesentery and retroperitoneum. It accounts for less than 1% of all soft tissue sarcomas. Subcutaneous ESOS and Giant cell rich subtype has an extremely rare incidence. Here we present the case of a 40 years old woman who presented with giant cell rich variant of extraskeletal osteosarcoma located in the subcutaneous plane of left thigh.
