回腸原発悪性リンパ腫による腸重積の1例

Abstract

A case of intussusception caused by malignant lymphoma is reported. A 74-year-old female, who had been visiting a practitioner with the chief complaint of rt-lower abdominal pain, visited our hospital for further examination. Ba enema study demonstrated an elevated lesion at the root of the ascending colon. Colonoscopy showed a mass on the ascending colon. Biopsy specimen revealed Group Ⅳ. Laparotomical examination showed that the terminal ileum invaginated into the ascending colon and she underwent right colectomy including the invaginated region because of difficulty of manipulation. Macroscopic examination of the resected specimen showed a mass near the terminal ileum with a shallow ulcer in the center and bridging fold around partially. The mass was like a submucosal tumor in appearance. Malignant lymphoma was suspected from macroscopic examination. Histological study revealed B cell type malignant lymphoma. Chemotherapy was undergone but was stopped temporarily because of side effects. She is being followed up as an outpatient in good condition.
