Treatment of palatal Kaposi's sarcoma (KS) with intralesional injection of vinblastine was seen to provide effective palliation. Of the ten patients studied, four had a 25% to 50% response, two 50% to 75% response, and four had 75% to 100% response with one or two intralesional injections of vinblastine. Response to treatment was followed for a mean of 3.6 months, with recurrence of lesions in two of ten patients.
