Solitary Colonic Ganglioneuroma: A Rare Incidental Finding of Hematochezia

Case Reports in Gastrointestinal Medicine
George Abraham, Sateesh R Prakash


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.
