 A total of 458 upper gastrointestinal tract endoscopies on 226 HIV(human immunodeficiency virus)infected patients between August 2004 and August 2010 were reviewed to clarify upper GI(gastrointestinal)lesions in cases with HIV infection. Histopathologically confirmed lesions included 42 CMV(cytomegalovirus)infections in 33 cases(15%),HSV(herpes simplex virus)infections in 5 cases(2%), candida infections in 36 cases(16%), giardiasis in 2 cases(0.9%),KS(Kaposi sarcoma)in 16 cases(7%)and idiopathic esophageal ulcer in 3 cases(1.3%).

 Among CMV infections, esophageal lesions were most common, observed in 76% of all cases, but characteristic punched out ulcers often observed in the middle and lower esophagus were only seen in 20% of cases. CMV gastric lesions were presented in the lower body and the antrum and 2/3 of the lesions were about 1cm in size and round or oval in shape erosive multiple lesions. Ninety-four percent of cases with KS had multiple lesions, and gastric lesions were seen in 81% of cases. Approximately 60% of KS were small lesions 10mm or less in size, and were round or oval submucosal tumor-like protrusions with various colors, such as bright red, dark red, dark purple and dark brown. Sixty-two percent of multiple protrusions were accompanied indentations and ulcers.

 Cases of HIV infections with upper GI tract lesions were all accompanied with decreased CD4 values. Mixed infections due to opportunistic infections were also observed.
