Abstract
A 53-year-old man complaining of abdominal pain was admitted to our hospital. CT showed a mesenteric tumor, measuring 8.0 cm in diameter, in the mesenteric root. Because of severe abdominal pain, an emergency laparotomy was performed. The operation revealed a mesenteric tumor adjacent to a trunk of the superior mesenteric artery and lymphnode swelling around the tumor. Extirpation of the tumor with partial resection of the ileum was done. The pathological diagnosis was malignant lymphoma, diffuse mixed B cell type. The postoperative course was uneventful, and the patient received R-THP-COP chemotherapy. He is alive without recurrence 6 months after operation.
