 We investigated the incidence of positive epithelioid cell granulomas which is regarded as a main factor in the criteria for the diagnosis of Crohn's disease (preliminary proposal) using biopsy specimens taken from conventional upper gastrointestinal (GI) endoscopy and colonoscopy. The incidence of positive granulomas was 43.3% (colon : 33.9%, upper GI 20.9%) in the initial endoscopic examination. This increased to 56.7% (colon : 42.1%, upper GI 30.7%) after consideration and additional examination. In morphologically different endoscopic lesions, incidence was highest in biopsy specimens taken from active colonic lesions (25.0%) . In conclusion, we suggest that it is unreasonable to rely only on the detection of granulomas for the diagnosis of patients with Crohn's disease. In our view, the diagnosis should also include various morphological and histopathological findings, such as epithelioid cell cluster, microaggregates of histiocytes, and focally enhanced gastritis.
