[Malignant melanoma and Kaposi's sarcoma (author's transl)]

A 46 years old woman with lymph node metastases of a malignant melanoma, without signs of the primary tumor developed in addition to it skin lesions of a Kaposi's sarcoma. Since the risk for developing additional primary malignancies is increased in melanoma patients, each patient must be carefully evaluated not only at the time of initial diagnosis but regularly thereafter. If diagnosed early and treated properly the additional tumor should result in no significant further risk to life.
