Limb-sparing surgery as an alternative for limb amputation in an invasive myxoid liposarcoma--case report

In medical practice, plastic surgeons confront with patients with sarcomas of the extremities that require a radical surgical approach. Knowing when to attempt limb-sparing surgery and when to give in to limb amputation is one of the most difficult decisions a surgeon can take. The correct approach and management of such cases ensure surgical success and the patient survival. In this paper, the case of a 56-year-old man, admitted in our clinic with a crush injury of the right calf and subsequent haematoma is presented. During haematoma drainage, the surgeon noticed abnormal tissue and performed an incisional biopsy. The patient was diagnosed with myxoid liposarcoma of the external compartment of the right calf. Limb amputation was proposed, but the patient refused. After the clinical examination, blood tests and diagnostic imaging, which allowed the correct evaluation of the case-tumor sizes and neighboring tissue reports, and preoperatory radiotherapy, limb sparing surgery, respectively primary tumor excision was decided to be performed. Negative margins could not be obtained by 3 successive resections or by adjuvant chemotherapy. The presented case supports the idea that limb-sparing surgery is only applicable to carefully selected patients with soft tissue sarcoma. In some cases, radical excision involving even mutilating amputations may provide a better oncologic and functional result.
