 A 50-year-old man came to our hospital with purpose of examination for positive fecal occult blood test. Colonoscopy revealed a smooth-surfaced, protruding lesion in the cecum. After spraying the indigocarmine dye, the border of the lesion was obscured. Magnifying endoscopy by narrow-band imaging technique revealed dilated and tortuous microvessels on the surface of the lesion. After spraying the crystal violet dye, a non-neoplastic pit was detected on the lesion and intervening part was dilated. These findings suggested that this lesion was a subepithelial tumor. Diagnostic endoscopic mucosal resection was performed and histological examination revealed spindle and ganglion cells in the lamina propria. Therefore, a diagnosis of ganglioneuroma was made.
