VEGA F., Ricardo et al. Colon schwannoma: Case report and literature review. Rev. chil. radiol. [online]. 2020, vol.26, n.4, pp.168-171. ISSN 0717-9308.

Schwannomas are mostly benign neoplasms that arise from the Schwann cells that form the peripheral neural sheath. Schwannomas of the gastrointestinal tract are rare and are considered separate entities from conventional schwannomas that originate in the soft tissues or in the central nervous system. Most gastrointestinal schwannomas occur in the stomach. Colon schwannomas are quite rare. We present the case of a 74-year-old man who with a colonic neoplastic lesion on the hepatic flexure, associated with a short invaginated segment and inflammatory changes. He underwent colonoscopy and subsequent surgical resection. The surgical specimen showed the presence of Verocay bodies and reactivity to the S-100 and GFAP markers respectively, that confirmed the presence of a colon schwanomma.
