A 80-year-old man with intestinal ganglioneuroma: A rare case

Ganglioneuroma (GN) is a rare benign neurogenic tumor, usually asymptomatic, which arises along the sympathetic ganglion chains. It accounts for more than 0.1%-0.5% of all tumors of the nervous system. Ganglioneuromas most frequently occurs the abdomen, however these tumors can grow anywhere sympathetic nervous tissue is found. Other common locations include the adrenal gland, paraspinal retroperitoneum, posterior mediastinum, head and neck. However, examples arising in the gastrointestinal tract are extremely uncommon. The main therapy for this lesion is the complete surgical excision. In this article we report a case of 80-year-old man with ganglioneuroma localized in a polypoid lesion of the sigmoid bowel.
