Extraskeletal osteosarcoma (ESO) is a rare variant of osteosarcoma that is situated in soft tissue and does not constitute an extension from primary osteosarcoma. We report a case of 60-year-old housewife who presented with an 8 months history of painful, ulcerated, lobulated and recurrent swelling. An incisional biopsy was also done which shows sarcomatous spindle cells and tumour giant cells against an osteoid background which is consistent with osteosarcoma in an extra skeletal location. Patient had surgical excision of the lesion and referred for chemoradiation therapy. There was no recurrence during 1 year follow up.
