Sodium pertechnetate Tc 99m radionuclide scanning is considered to be a sensitive indicator in detecting lesions of Kaposi's sarcoma, including occult infiltrations. This report describes a "falsepositive" scan in a patient with acroangiodermatitis (pseudo-Kaposi's sarcoma); therefore, this technique may not be useful in the differential diagnosis of these two clinically and histologically similar diseases. We suggest, instead, that the technetium scan may be helpful in deciding on the course of therapy in acroangiodermatitis by demonstrating the nature of the underlying vascular anomalies.
