Abstract
A man in his fifties had an upper gastrointestinal X-ray examination, and the examination revealed multiple elevated lesions in his gastric body. He had a secondary endoscopic examination that showed multiple dusky-red elevated lesions similar to hyperplastic polyps in the stomach. After one month, he had tarry stools and a high fever, and he was diagnosed as having acquired immunodeficiency syndrome (AIDS). We added immunohistochemical staining to the biopsy specimens from the secondary endoscopic examination. The multiple elevated lesions histopathologically are identified as Kaposi's sarcoma. In those patients where multiple elevated lesions are identified which are dusky-red, with a central depression and superficial irregularity, AIDS-related Kaposi's sarcoma should be borne in mind as a potential diagnosis.
