 Eight patients with Crohn's disease having aphthoid ulcers and/or small ulcers (less than 5 mm) as the only radiographic and endoscopic abnormalities were presented, and characteristics of the lesion, distribution, histology of biopsy specimens and clinical course were studied.

 1) Multiple aphthoid ulcers of the stomach and rectum were demonstrated by dye-spraying method in all of the eight patients. Those of the duodenum were found in seven patients.

 2) Aphthoid ulcers or small ulcers in the small bowel were recognized in six patients, and in the colon, they were recognized in seven patints.

 3) Non-caseating epithelioid cell granulomata were found in six patients, and granulomatous lesions were found in one patient by histological study of biopsy specimens with serial sectioning employed in some cases.

 4) Seven patients were diagnosed as having Crohn's disease, and the other one was diagnosed as being a suspected case of Crohn's disease on the basis of radiographic and endoscopic findings and histology of biopsy specimens.

 5) Progression from aphthoid ulcers to overt changes of eccentric rigidity and cobblestoning was found in one case after a follow-up for six years and three months. On the other hand, in another case aphthoid ulcers disappeared during the course of five years and eight months. The clinical course of aphthoid ulcers was variable. They improved in some cases, but were either unchanged or showed recurrence in other cases. From those results and discussion of the literature it was speculated that aphthoid ulcers represent an abnormal macrophage function of the whole gastrointestinal tract, and that they may remain unchanged for a comparatively long period of time, or show rapid disappearance or rapid progression to longitudinal ulcers and cobblestoning under the influence of certain factores.
