RESUMO
Gastritis cystica polyposa was diagnosed in three patients with ages of 49, 56 and 66 years. All patients had been operated on for gastric cancer 1 to 5 years earlier, with Billroth II gastroenteric anastomose being made at that time. The lesions were diagnosed by regular follow-up endoscopic examination without any presenting symptoms. Macroscopically, all lesions were located on the gastric side of the anastomosis, with polypoid growth of 1.5x1.0, 2.0x1.5, and 0.5x0.5 cm in size respectively. The surfaces of the lesions were coarsely nodular and brittle, and one of them protruded into the anastomosis lumen. Histologic examination revealed polypoid mucosal changes associated with functionally active, hyperplastic and cystic dilatation of the glands which had infiltrated to into the underlying submucosa. An endoscopic polypectomy was performed in two patients, and all has gone well, without evidence of a recurrent tumor 6 & 18 months after polypectomy. The other patients refused a polypectomy. Gastritis cystica polyposa should be differentiated from a stump carcinoma to avoid a further unnecessary surgical intervention. Awareness of the entity will lead to better diagnosis of gastritis cystica polyposa.
