 In order to make a diagnosis of systemic disease from an analysis of shape and distribution of GI lesions, it is important to analyze the GI lesions as well as the patient's clinical background. A patient's clinical background, the activity of the original systemic disease and whether the patient uses drugs such as non-steroidal anti-inflammatory drugs are important sources of information. For a diagnosis of GI lesions obtained by radiologic or endoscopic examinations, it is important to analyze the location, shape and the properties of the surrounding mucosa of the lesions. GI lesions associated with systemic disease can be divided into the following six patterns proposed by Watanabe, et al. : i) longitudinal ulcer type ; ii) circular ulcer type ; iii) round or oval ulcer type ; iv) cobblestone or inflammatory polyposis type ; v) edema, redness, erosion type and vi) multiple tumorous protrusion type. When GI lesions are detected in patients with systemic disease, the diagnosis and the differential diagnosis of the systemic disease can be made by analyzing the lesions and determining which patterns the detected lesions belong to.
