A case of early gastric cancer occurred from juvenile gastric polyposis

Abstract

A 31-year-old man had been diagnosed as iron deficiency anemia at 27 years of age, and gastrointestinal endoscopy at the time revealed numerous small and large polyps at the gastric angles and in the antrum. The pathological diagnosis was juvenile polyps of the stomach, and a further study revealed adenocarcinoma in a small area of the lesion. Piecemeal endoscopic mucosal resection was performed, and recurrence of a polypoid lesion and atypical epithelium were found around the scar after the follow up of about 3 years. Distal gastrectomy and lymph node dissection was performed. Juvenile polyposis is generally recognized as characterized as benign hyperplastic polyps, but its malignant potential has recently been noted. Generally total gastrectomy is recommended for juvenile polyposis of the stomach. Local resection or distal or proximal gastrectomy may be used to treat localized lesions.
