Metastatic liposarcoma in the jejunum causing intussusception: report of a case.

We report a case of metastatic liposarcoma in the jejunum manifesting as intestinal intussusception. A 75-year-old man underwent wide excision of a dedifferentiated liposarcoma in his left thigh, followed by adjuvant radiation therapy. He was referred to our department 7 months later with colicky abdominal pain and vomiting. Abdominal radiography showed an intussusception of the small intestine. Laparotomy revealed an antegrade jejunojejunal intussusception, and we resected the jejunum containing the tumor without attempting manual reduction. Histological examination confirmed that the tumor was a metastasis of the liposarcoma. The patient died of pulmonary metastasis 3 months later.
