Kaposi'S sarcoma of the stomach and duodenum in human immunodeficiency virus infection.

Kaposi's sarcoma (KS) of the upper gastrointestinal tract without extensive cutaneous disease is uncommon and usually asymptomatic. Herein, the case of a 37-year-old man who presented with iron deficiency anemia is reported. A colonoscopy was unremarkable and upper endoscopy revealed multiple raised, hemorrhagic, plaque-like lesions throughout the stomach and the small intestine. Histopathology confirmed KS; further testing revealed the patient to be HIV-positive and a diagnosis of AIDS-related KS was made. Although a rare entity, physicians should be aware of this condition in order to facilitate a prompt diagnosis and necessary intervention.
