Solitary schwannoma of the cecum: case report and review of the literature

José Wilson Benevides de Mesquita Neto et al. Case Rep Oncol. 2013 Jan.

Abstract

A 78-year-old woman presented with an abdominal mass diagnosed by ultrasound and computed tomography. The patient underwent a laparotomy, during which a retroperitoneal tumor adherent to the cecum wall was identified. Microscopically, it showed spindle-cell proliferation in whorls, with low mitotic count (2 per 50 high-power fields) and was strongly positive for S-100 protein and vimentin. The final diagnosis was benign schwannoma of the cecum and no further treatment was required. Large intestine schwannomas are extremely rare tumors and only a few cases of schwannoma of the cecum have been reported to date.

Keywords: Cecum; Gastrointestinal tract; S-100 protein; Schwannoma.
