A 66-year-old male was admitted to our hospital with sudden abdominal pain. An enhanced abdominal CT scan revealed an enhanced tumor measuring 2.5cm in diameter which invaginated into the ascending colon from the ileum. Insertion of a long intestinal tube improved the ileus and reduced the intussusception. We performed laparoscopy-assisted partial resection of the small intestine under the suspicion of GIST or lymphoma. The tumor was diagnosed as a diffuse large B cell lymphoma based on the histological findings. Chemotherapy led to complete remission. Malignant lymphoma that occurs in the small intestine as its primary site has been diagnosed in some cases as intussusception. In cases of intussusception caused by a small intestinal tumor, preoperative decompression and diagnosis should be attempted to the greatest extent possible, and laparoscopy-assisted resection immediately followed by initiation of chemotherapy may result in favorable outcomes.
