Abstract
A case of Intussuscepted primary malignant lymphoma is reported, preoperatively confirmed by colonoscopic biopsy and treated with laparoscopic ileocecal resection. A 75-year-old male was admitted to our hospital complaining of abdominal pain and distention. Abdominal ultrasonography revealed the multiple-concentric-ring sign with a hypoe - choic area in the center. Abdominal computed tomography showed an ileo-colon type intussusception with the tumor in the lead. Colonoscopic examination revealed a tumor 4 cm in diameter in the ileum, about 20cm proximal to Bauhin's valve. The tumor was diagnosed as a malignant lymphoma by biopsy and surgery was performed. The histopathological findings showed that the tumor was a malignant lymphoma of the diffuse large cell type. CHOP therapy was added after the operation, and the patient is alive 20months postoperatively. We reviewed 114 cases of primary ileal lymphoma complicated by intussusception reported in Japan, and analyzed the cases.
