title: [Rare case report of solitary ganglioneuroma of the transverse colon].
abstract: We report herein a rare case of solitary ganglioneuroma occurring in the transverse colon with a brief literature review. A 45-year-old man was diagnosed as having hemorrhoids by a local medical practitioner and referred to our hospital for further examination. He showed neither signs nor symptoms of neurofibromatosis and multiple endocrine neoplasia. Colonic endoscopic examination demonstrated that a pedunculated polyp with a size of 11 mm in the diameter in the transverse colon. Histopathologic and immunohistochemical examination demonstrated that the endoscopic mucosal resection specimen of the polyp had abundant ganglionic cells, Schwann cells, and nerve fibers in the mucosa and submucosa.
