An intussusception due to @entity694 has sometimes been reported. However, to the best of our knowledge, reports of intussusception due to @entity420 are extremely rare. In this report, the case of a young @entity1 with @entity420 causing intussusception is described. A 24-year-old @entity1 visited a hospital complaining of @entity490 , and an @entity5 was diagnosed by colonoscopy. Computed tomography showed intussusception caused by a large @entity5 in the pelvis and absence of distant metastases. Locally advanced @entity5 causing intussusception was diagnosed, and a low anterior resection was performed. Intraoperatively, repair of the invagination could not be accomplished easily; therefore, the repair was abandoned. Instead, the @entity5 was removed en bloc to avoid dissemination of the @entity5 . Histopathologically, the @entity5 was diagnosed as a poorly differentiated @entity420 , pStage IIA. The @entity1 has no evidence of recurrence at 10 mo after the operation.
