Abstract:
Leiomyosarcoma is a malignant tumor showing smooth muscle differentiation, and it accounts for 2% to 8% of soft tissue sarcoma. Clinically, substantial mortality and morbidity are related to the propensity for distant metastasis and local recurrence, respectively. Microscopic findings characteristically reveal intersecting bundles of spindle-shaped cells having fibrillar cytoplasm and blunt-ended nuclei. Immunohistochemistry for intermediate filaments is helpful in establishing a definitive diagnosis. We experienced a case of large protruding leiomyosarcoma that developed on an old burn scar of the medial calf of a 45-year-old man. On preoperative evaluation, we recommended amputation due to a distant metastasis to the lung(stage IV). As the patient refused amputation of his lower leg, the tumor was radically excised and immediate reconstruction was done using free latissimus dorsi muscle flap and skin graft. Four months after excision despite adjuvant chemotherapy, amputation was performed due to local recurrence.
