Unusual Visceral Sarcomas: Report of 2 Cases with Review of Literature

Abstract

Sarcomas account for only 1% of adult solid tumours. Visceral sarcomas except Gastrointestinal Stromal Tumours (GIST) are rare and therefore little is known about the natural history and prognosis of these tumours. They tend to occur in older adults with no sex predilection and are characterized by an aggressive behaviour. Proper evaluation of these tumours is necessary because these are uncommon tumours which often present with advanced disease in an anatomically complex location. Since there are very few published studies on visceral sarcomas, the data is insufficient to suggest prognosis and optimum treatment strategies. We present two cases of such unusual malignancies in spleen and urinary bladder.
