Abstract
A case of carcinoma in remnant stomach as the complication of stomal polypoid hypertrophic gastritis (gastritis cystica polyposa) was reported. The patient was 54-year-old male to whom subtotal gastrectomy was carried out under a diagnosis of IIc III+ like advanced gastric carcinoma 19 years ago. He was admitted to our hospital because of further evaluation of green caterpilar-like protruded lesion in the remnant stomach. Similar finding was observed in the greater curvature proximal to the stoma by x-ray and endoscopic examinations. The mucosa with partial redness and erosion in the protruded lesion was gradually shifted to the normal mucosa. Biopsy from the erosion revealed group V. Partial resection of remnant stomach was performed under a diagnosis of remnant gastric carcinoma. Histology of resected speci-men was as follows; 1) Moderately differentiated adenocarcinoma limited to the invasion into the mucosa in the surface of the protruded lesion. 2) Below this layer, there are slight elongation of gastric areola, proliferation of pseudoantral glands with cystic formation, and slight degree of chronic cell infiltration indicating stomal polypoid hypertrophic gastritis. In addition, twenty-two cases of stomal polypoid hypertrophic gastritis including 11 cases which complicated carcinoma reported in Japan were briefly reviewed.
