Anterior abdominal wall extraosseous osteosarcoma, occurring 40 years after para-aortic irradiation

Extraskeletal osteosarcomas (OSs) are highly malignant soft tissue tumours associated with a poor prognosis. Only a few records of these rare aggressive neoplasms have been reported in the literature.

We describe the case of a 49-year-old man, who presented to our tertiary care centre with a painful isolated lump around the umbilicus. After surgical biopsy, imaging and subsequent pathological analysis, the swelling was diagnosed to be a localised extraskeletal OS. He received previous radiation as treatment for testicular seminoma 40 years ago, which has been in remission ever since. He also happens to have testicular hydrocele since 10 years. He was subjected to resection and free flap reconstruction complicated by lower anterior abdominal wall haematoma and large pseudoaneurysm of the left femoral artery. Patient completed 60 Gy of adjuvant electron beam irradiation for close margins and is scheduled for adjuvant chemotherapy. We describe a brief account of his illness.
