A CASE REPORT OF ENDOSCOPICALLY REMOVED CAECAL NEUROFIBROMA

Abstract

We reported the first case of colonic neurofibroma in Japan. A 52-year-old man visited our hospital for routine check up and diagnosed to have caecal submucosal tumor. X-ray and endoscopic studies showed a subpedunculated polyp with smooth surface. Endoscopic polypectomy was successfully performed. The tumor was 10×10×7.5 mm in diameter and consisted of yellowish solid tissue. Microscopically, the tumor had no capsule and consisted of fusiform cells. The tumor cells showed immunoreactivity to S-100 protein and diagnosed as neurofibroma.
