A case of renal cutaneous metastases simulated Kaposi sarcoma and the condition was misdiagnosed as Kaposi sarcoma. A new technique was employed using the isotope technetium 99m as the compound sodium pertechnetate Tc 99m for the diagnosis and evaluation of the extent of Kaposi sarcoma. The failure to demonstrate a positive isotope scan in our case was a clue to the incorrect diagnosis of Kaposi sarcoma.
