Epidemic and classic Kaposi's sarcoma of the feet. A comparative study.

The clinical behavior of Kaposi's sarcoma involving the feet is compared for patients with and without AIDS. Although AIDS-related Kaposi's sarcoma is less likely to be confined to the legs than is non-AIDS-related Kaposi's sarcoma, the legs are the most common site of disease in both forms. Kaposi's sarcoma occurring in the AIDS setting is as radiosensitive as that which occurs in the patient without AIDS. Palliative radiotherapy can offer substantial relief for affected patients.
