Epidemiologic aspects of american Kaposi's sarcoma.

In our series of 37 patients with Kaposi's sarcoma, a larger than expected incidence of Americans of Italian and Jewish lineage was found, with 51% of Italian and 38% of Jewish background. Although a predominance of these two groups has been clearly shown previously, this may be the highest percentage of any series. In addition, 12, or 32%, of the patients were found to have concurrent diabetes mellitus. This association has been observed previously, but is not generally appreciated.
