Extraskeletal osteosarcoma

ABSTRACT

A 50 years old male presented with ulcer and swelling in left leg for 2 years. X-ray showed soft tissue sarcoma and excision was done. A diagnosis of extraskeletal osteosarcoma was made. Extraskeletal osteosarcomas are rare malignant mesenchymal neoplasms. By definition, these are located in soft tissue without primary involvement of bone or periosteum. Since these tumours mimic other soft tissue tumours and tumour like conditions, radiology and histopathotogy alongwith tumour markers studies are important in diagnosis of this tumour
