Ganglioneuromas (GNs) are hamartomatous tumors derived from the autonomic nervous system. It is rare to encounter GN in the gastrointestinal tract. Patients with these tumors usually present with abdominal pain, constipation, ileus, weight loss, or even bleeding. GNs are categorized into three different morphological subtypes, namely, polypoid GN, ganglioneuromatous polyposis, and diffuse ganglioneuromatosis. We present a case of hematochezia from GN in a colon polyp discovered on diagnostic colonoscopy. Due to a lack of guidelines, we reviewed the literature to discuss treatment and other associated conditions for GN...

Ganglioneuroma (GN) is a benign neoplasia of the autonomous nervous system, colonic GN is uncommon in adults. There are three subgroups: polypoid GN, ganglioneuromatous polyposis and diffuse ganglioneuromatosis. Ganglioneuromatosis is highly-associated to neurofibromatosis type 1 (NF1) and multiple endocrine neoplasia type 2b (MEN2B). A 68-year-old female, with a discrete retarded emission of stools, was admitted for a large tumor in the left flank; CT scan, urography and barium enema demonstrated a large retroperitoneal mass, presumed as sarcoma...

REVIEW
Owen T M Chan, Parviz Haghighi
Intestinal ganglioneuromas comprise benign, hamartomatous polyps characterized by an overgrowth of nerve ganglion cells, nerve fibers, and supporting cells in the gastrointestinal tract. This polyposis has been divided into 3 subgroups, each with a different degree of ganglioneuroma formation: polypoid ganglioneuroma, ganglioneuromatous polyposis, and diffuse ganglioneuromatosis. The ganglioneuromatous polyposis subgroup is not known to coexist with systemic disorders that often have an associated intestinal polyposis, such as multiple endocrine neoplasia type IIb, neurofibromatosis type I, and Cowden syndrome...

Ganglioneuromatous polyposis is a very rare intestinal disease which differs from isolated polypoid ganglioneuroma and from diffuse ganglioneuromatosis. Its clinical, endoscopic, microscopic and evolutive features are poorly known. We report three cases of colonic ganglioneuromatous polyposis that illustrated an uncommon diffusion pattern in two men and one woman aged 63-72 who presented with chronic diarrhea. Endoscopic features suggesting the diagnosis were diffuse polyposis predominating in the cecum and right colon, with hyperhemic flat lesions enhanced after indigocarmin instillation...

We studied 43 patients with ganglioneuromas of the gastrointestinal tract accessioned at the Armed Forces Institute of Pathology (AFIP) from 1940 to 1990 in order to determine their relation to von Recklinghausen's disease and other multiple tumor syndromes. They fell into three groups: polypoid ganglioneuroma (28 patients); ganglioneuromatous polyposis (7 patients); and diffuse ganglioneuromatosis (8 patients). Follow-up (1-24 years, average 8 years) for 16 of 28 patients with polypoid ganglioneuroma showed that none of these patients developed von Recklinghausen's disease or evidence or multiple tumor syndromes...

The unique familial occurrence of polypoid intestinal ganglioneuromatosis of the large bowel is reported. The lesions affected a 38-year-old father and three children aged 14, 12, and 10 years. In these cases, extensive diffuse and polypoid proliferation of nerve fibers and ganglion cells within the colonic mucosa was associated with pronounced epithelial changes resembling juvenile polyposis. None of the patients had any clinical evidence of the mucosal neuroma syndrome or Von Recklinghausen's neurofibromatosis, conditions in which intestinal ganglioneuromatosis can occur...
