Solitary metastasis of myxoid liposarcoma from the thigh to intraperitoneum: a case report

BACKGROUND: The purpose of case report was to present a rare case of a solitary metastasis of myxoid liposarcoma and discuss the clinical and pathological information for patients treated for metastatic myxoid liposarcoma. CASE PRESENTATION: We report our experience with a case of solitary metastasis of myxoid liposarcoma from the thigh to intraperitoneum. The patient was a 60-year-old man who was referred for abdominal discomfort and fatigue. Enhanced computed tomography showed a 25-cm intra-abdominal tumor. He had undergone a wide local excision for a right thigh myxoid liposarcoma 6 years earlier. At laparotomy, a huge multi-lobular cystic mass was identified at the small bowel mesentery. Wide local excision was performed, and the mass was diagnosed as metastatic myxoid liposarcoma. He was discharged without postoperative complications. CONCLUSIONS: We experienced a single intraperitoneal metastasis in a patient with myxoid liposarcoma after radical surgery of the primary site.
