Abstract

|
Soft tissue sarcomas of popliteal fossa are rare, accounting for less than 5% of all soft tissue sarcomas of the extremities. In an extracompartmental space such as the popliteal, cubital fossa and inguinal space, where major vessels and nerves traverse, performing resections with wide margin is difficult and sometimes marginal margin is inevitable for limb salvage. For popliteal tumor resection, posterior approach would be a classic method. For tumors with small size and not adherent to surrounding structures, tumor is easily resected by this approach and dissection of nerve sheath or adventitia of vessel. On the contrary, tumors of large size and infiltrating the posterior structure of knee joint may show difficulty in en-bloc resection itself. These cases were candidates for amputation. Furthermore, tumors involving both popliteal fossa and anterior compartment usually had no choice but to have an amputation to prevent local recurrence. We regarded soft tissue sarcoma showing this kind of presentation as bone tumor having extraosseous mass. We performed wide en-bloc resection of proximal tibia and fibula along with sarcoma involving both compartment on liposarcoma of 47-year old man.
