Abstract

Isolated neurofibromas that affect the gastrointestinal tract are rare and almost always manifest as neurofibromatosis type 1 or multiple endocrine neoplasia type 2b. In this paper, we present a case of a 24-year-old female with abdominal pain who discharged a neurofibroma in her stool without any blood on it. A colonoscopy showed multiple small polyps in the sigmoid colon and a nodule in the ileocecus. The pathology results and the immunohistochemical stains of the removed neoplasm from the ileocecus confirmed the diagnosis was a bowel neurofibroma. We report a rare case of ileocecal neurofibroma due to the patient’s affected gastrointestinal tract, without any associated systemic syndrome other than a neurofibroma discharged in the stool.

Keywords: Neurofibroma; Isolated; Gastrointestinal tract; Ileocecus; Clinical presentation

Core tip: Neurofibromas of the gastrointestinal tract are rare, and various types have been previously reported. However, to our knowledge, this is the first report of a neurofibroma discharged from the patient’s intestine with stool without any other associated systemic syndromes.
