Giant Dumbbell Liposarcoma Thigh Extending to the Retroperitoneum - The Ideal Surgical Approach and Reconstruction - A Case Report and Review of Literature

Dumb bell shaped tumours have been reported infrequently in literature of which the usual ones being retroperitoneal tumours extending to the scrotum via the inguinal canal or extending through the femoral canal and presenting in the thigh. Cases of a thigh liposarcoma extending to the retroperitoneum are very rare. We could come across only publications in this regard 5. We report a patient with a large liposarcoma of the thigh extending to the retroperitoneum via the femoral canal. Oncologically sound resection continues to be a challenge in large retroperitoneal tumours with dumb bell extension as in other retroperitoneal tumours due to the large size at presentation. The thoroughness and integrity of the first excision is vital to determine its curative effect 2. The approach for such tumours and reconstruction post resection should be an essential part of planning. We present our experience of the combined en bloc excision of the dumb bell tumour and reconstruction along with the review of the available literature.
