Abstract

A liposarcoma is commonly found in the thigh, the buttocks, and the retroperitoneum, but rarely in the hands and feet. We reported a case of liposarcoma of the sole, that had reccured repeatedly, in 46-year-old male. The initial histological diagnosis was angiosarcoma, and the patient underwent wide resection. One year and 6 months after original surgery, he had local recurrence and lymph node metastasis. Later, reexamination led to the conculusion that the tumor was a round cell liposarcoma. In cases of recurrence, the histologic features of the tumor occasionally change to high-grade malignant type. In view of this possibility, complete surgical excision is very important in the initial treatment of liposarcoma.
