The incidence of Helicobacter pylori-negative gastric cancer is very low. A 60-year-old man was referred to Tokai University Hospital from a local clinic because of eosinophilia. The laboratory data revealed prominent eosinophilia, with a white blood cell count of 7,900 /μL and increased eosinophil granulocyte level of 1,659 /μL. After an examination for secondary eosinophilia, esophagogastroduodenoscopy showed an enlarged gastric fold in the corpus, suggesting type 4 gastric cancer. Repeated esophagogastroduodenoscopy (EGD) and a re-biopsy demonstrated poorly differentiated adenocarcinoma and signet ring cell carcinoma. The patient was negative for Helicobacter pylori infection according to the serum anti-Helicobacter pylori antibody, culture and histopathological findings.
