Kaposi-Sarkom des Magens als ungewöhnliche Erstmanifestation einer HIV-Infektion (AIDS)

A 47-year-old African man complaining of epi-gastric pain since one year was seen by a doctor for an ambulatory gastroscopy. In the recurring gastroscopies the gastric body contained widely distributed ulcerations which still remained after a successfully Helicobacter pylori eradication. Histologically there was an erosive inflammation with foveolar hyperplasia. For further diagnostics the patient was admitted to hospital. Endosonography showed scattered thickening of the mu-cosa and submucosa with augmented vascularisa-tion. Further more a rugectomy with maximally coagulation was made. Only after several biop-sies we were able to diagnose an AIDS-related -Kaposi’s sarcoma of the stomach instead of the initially -favored diagnosis of a GIST (gastrointestinal stromal tumor).
