Endoscopic treatment of ganglioneuroma of the colon associated with a lipoma: a case report

INTRODUCTION: Ganglioneuromas are rare benign peripheral neuroblastic tumors characterized by hyperplasia of ganglion cells, nerve fibers, and supporting cells. They are not usually localized in the colon. CASE PRESENTATION: A 61-year-old Caucasian man was admitted to our department for colon cancer screening. A colonoscopy revealed a lipoma of 5cm in diameter, two micropolyps of less than 1cm, and one sessile polyp of 0.6cm in diameter. The polyps were removed with hot biopsy forceps. A histological examination revealed two hyperplastic polyps and one ganglioneuroma polyp. A follow-up colonoscopy showed no signs of recurrence after 16 months. CONCLUSIONS: Although a few cases of lipomas associated with ganglioneuromatous syndrome have been reported, the association of an intestinal lipoma with an isolated ganglioneuroma polyp has not been described. The implications of this association are unknown.
