A Case of Intussusception of the Small Intestine due to Recurrent Malignant Lymphoma

Abstract

We report herein on a case of intussusception due to recurrent malignant lymphoma of the small intestine. A 77-year-old man was diagnosed as having malignant lymphoma (diffuse large B-cell lymphoma) of the left ethmoidal sinus. R-CHOP therapy was performed, and the patient achieved complete remission. The patient was admitted to our hospital with lower abdominal pain and vomiting two years later. Computed tomography showed intussusception of the ileum. We performed an emergency laparotomy and partial resection of the small intestine. The specimen included a 7.0×4.5 cm tumor. Immunohistological examination demonstrated recurrent malignant lymphoma. Malignant lymphoma sometimes recurs in the small intestine and induces intussusception even if patients achieve complete remission. In this situation, it is desirable to perform early surgery with this disease in mind.
