A CASE OF PYOGENIC GRANULOMA IN THE SIGMOID COLON TREATED WITH ARGON PLASMA COAGULATION

Pyogenic granuloma (PG) with hemorrhagic tendency, is often recognized in the oral mucosa and skin, but rare in the gastrointestinal tract. Only 20 cases have been reported in the gastric mucosa. There have been no reports of gastrointestinal PG treated by argon plasma coagulation (APC). We report here the first case of PG in the sigmoid colon treated by APC. The patient was a 64-year-old woman complaining of constipation who was referred to a university hospital of Kochi Medical School. She presented with easily bleeding mucosa, as revealed by a total colonoscopic study in the sigmoid colon. Magnifying colonoscopic examination showed two sessile small polyps in the sigmoid colon. Pathological examination of the biopsy specimens revealed pyogenic granuloma. We treated this lesion by endoscopic APC. No recurrence has been found as of 9 months after APC therapy.
