An 85-year-old woman was introduced to our hospital because of a massive subcutaneous tumor in her left lumbar region that occurred after she fell and contused that region in January 2011. She was treated as subcutaneous hematoma by a local doctor, and the tumor had rapidly enlarged since August 2011. When she visited our hospital in September 2011, she presented with a 15×12×8 cm subcutaneous tumor with a glossy surface on her left lumbar region, together with heat. A pleomorphic sarcoma or liposarcoma was suspected by skin biopsy. On this basis, the tumor was resected with a 3-cm margin and the peritoneum was kept. The left iliac crest was resected, because the tumor was adhered to the left ilium. The defective part was reconstructed by an anterolateral thigh flap and a split-thickness skin graft. Myxofibrosarcoma was finally diagnosed by pathological examination of operative specimen. During regular consultations by computed tomography imaging, she had no recurrence and no metastasis, but suddenly died in a sanatorium postoperatively three years and five months after.
