A carcinoid tumor of the rectum in a patient with neurofibromatosis type 1 performed by laparoscopy assisted low anterior resection—a case report—

Abstract

We report a case of carcinoid tumor in the lower rectum of a patient with neurofibromatosis type 1. A 53-year-old man with neurofibromatosis type 1 was diagnosed with a submucosal tumor in the lower rectum at another hospital. Biopsy specimen showed a rectal carcinoid tumor. He was admitted to our hospital and had a laparoscopy assisted low anterior resection. Histopathological examination of the surgical specimen resulted in a final diagnosis of carcinoid tumor of the rectum. Periodic surveillance would be required, because neurofibromatosis type 1 frequently accompanies malignant tumors. Although it is a rare disease, it should be considered that a rectal carcinoid tumor might be complicated in a patient with neurofibromatosis type 1.
