Introduction
Lower gastrointestinal bleeding is an ominous symptom associated with a wide range of etiologies among them neoplasms (1). Most of the neoplasms arising in the gastrointestinal tract are from the epithelium or mesenchyme, with primary hematologic neoplasms representing a very low proportion of total tumors (2). Epithelial and mesenchymal tumors can have a polypoid endoscopic configuration, with histopathological tissue analysis being necessary for distinction and definitive diagnosis. Neoplasms deriving from the epithelium are most commonly adenomas and adenocarcinomas while those deriving from the mesenchyme are primarily gastrointestinal stromal tumors (GIST) (3). Furthermore, while tumors of a neural origin in the gastrointestinal tract a rare, a wide range of these tumors have been described (4–6). We present a case of a symptomatic gastrointestinal schwannoma presenting as an ulcerated colonic sessile mass.
