The radiology corner: Kaposi's sarcoma of the stomach.

Kaposi's sarcoma is a systemic, multicentric and slowly progressing vascular tumor which usually affects the skin. Visceral involvement is common, may follow or precede the cutaneous involvement and rarely, may be the only manifestation of the disease. Gastric sarcomatous lesions are characterized by the presence of multiple submucosal or intraluminal nodules affecting a part or the entire stomach and simulating large gastric rugae. A case of isolated gastric Kaposi's sarcoma affecting the greater curvature of the stomach is presented, illustrated and discussed together with a short review of the pertinent literature.
