Giant dedifferentiated retroperitoneal liposarcoma.

: A 72 years old lady presented with a gradually increasing abdominal mass for the last 25 years, with more rapid increase in the last 05 years. Examination revealed a large mass spanning the whole abdomen. CAT scan revealed a huge retroperitoneal tumour, with tortuous ureters passing through the tumour and three tiny nodules in the right lung field. A subtotal piecemeal excision of the tumour was done after stenting the ureters with single J stents. The excised tumour mass weighed 46 Kg. The patient had a prolonged ileus that recovered in 5 days. Histopathology revealed the mass to be dedifferentiated liposarcoma. The patient and the family were satisfied with the short-term outcome of the surgery. She was ambulating with little support and was able to manage her daily affairs.
