Kaposi’s sarcoma may be associated with other neoplasm, and this may indicate that Kaposi’s sarcoma is related with altered immunologic surveillance. There has been only one reported case of Kaposi’s sarcoma with concomitant pancreatic cancer in Korea, but Kaposi’s sarcoma with concomitant colon cancer has not been reported in Korea. We report here on a case of Kaposi’s sarcoma with concomitant colon cancer in an 82-year-old Korean woman who had no other evidence of immunosuppression.
