A 36-year-old man received a subtotal gastrectomy for Borrmann type 2 advanced carcinoma in the antrum of the posterior well. Preoperatively, peripheral white blood cell count was 16,400/mn3 with 80% of neutrophils. Microscopically, the tumor was of a poorly differentiated adeocarcinoma with intense eutrophilic infiltration which was totally confined within the neoplastic portion and in the metastatic focus in the regional lympho nodes. Repeated postoperative whits blood cell counts dropped down to the normal level. Neither infectious nor knowledge, this is the first case of gastric carcinoma with massive neutrophilic stromal reaction(inflammatory carcinoma) and leukocytosis in the literature in the korea.
