 A 79-year-old woman with a history of therapy for malignant lymphoma in June 2010 was found to have a tumorous lesion in the pelvic cavity on the right side of the rectum on an abdominal computed tomography (CT) examination performed at that time. On the abdominal CT examination performed in 2016, the lesion was larger and showed internal aeration that suggested a connection to the rectum. On colonoscopy, there was an opening at the upper rectum, and purulent discharge was observed from it. Since tumorous lesions such as GIST were suspected, laparoscopic tumor resection was performed. On pathological examination, spindle-shaped tumor cells in an interlaced bundle pattern were seen. Immunohistochemical findings were α SMA (+), desmin (+), c-kit (-), CD 34 (-), and S-100 (-). The final pathological diagnosis was leiomyoma of the rectum. Since the concept of GIST has been established, leiomyoma of the gastrointestinal tract has become rare. In this report, a case of rectal leiomyoma with extramural growth and penetrating to the rectum that was resected by laparoscopic surgery during follow-up after treatment for malignant lymphoma was presented.
