Kaposi's sarcoma of the intestinal tract: roentgen manifestations.

Five cases of generalized Kaposi's sarcoma are reported with roentgen evidence of involvement of the intestinal tract. In three instances, there was extensive involvement of the small bowel with multiple intramural nodules. The fourth patient demonstrated multiple polypoid lesions of the colon, and in the fifth a constricting lesion of the ileum was present. Two patients with small bowel involvement had significant malabsorption. This latter complication of diffuse Kaposi's sarcoma of the small bowel has not been previously reported. The diagnosis of the nature of the roentgen intestinal abnormality can usually be made, because intestinal involvement generally occurs late in the disease, when both extensive cutaneous nodules and edema of the extremities are apparent.
