A myxoid liposarcoma in the lower leg, with a large intra-abdominal metastasis

Abstract

We report a patient with a large intra-abdominal metastasis of myxoid liposarcoma. The patient first noticed an asymptomatic mass in her left leg in 1985, when she was 20 years old. The mass was left untouched until she realized its rapid growth and consulted a local doctor in 1994. After needle biopsy, she was histologically diagnosed as having a myxoid liposarcoma. She disagreed with the recommendation for an amputation below the knee, made at another hospital. A marginal resection was performed as an alternative treatment. She subsequently underwent three more marginal resections and four intra-lesional resections for repeated local recurrences. In 1997, an abdominal computed tomography scan revealed the presence of multiple intra-abdominal metastases, and the lesions were judged to be inoperable. Ileus and respiratory distress, caused by compression by the abdominal mass, gradually worsened, and she died in 1999, at the age of 34. The girth of her abdomen was 135cm at the time of death.
