An 18-year-old man initially presented to a clinic with chief complaints of right lower abdominal pain and diarrhea. He was then referred to our hospital for suspected appendicitis. On admission, abdominal computed tomography showed ileocecal intussusception, and a laparoscopic ileocecal resection was performed. Intraoperative findings showed an invasion of the terminal ileum and cecum into the ascending colon. Macroscopically, several small nodules were found on the lumen of the ileocecal valve. In addition, the wall of the cecum was thickened and the surrounding lymph nodes were swollen. On histopathological assessment, there was proliferation of lymphoid follicles in the ileocecal mucosa. Thus, the diagnosis of intussusception due to lymphoid hyperplasia (LH) was made.
