[Kaposi's sarcoma and kidney transplant]

Ex novo Kaposi's Sarcoma 4 months after renal transplantation in a young patient is described. Progression of the tumoral lesions has been observed during combined immunosuppressive treatment with Prednisone, Azathioprine and Cyclosporin. Stopping Azathioprine and Cyclosporin as well as reducing Prednisone prevented new lesions and made the preexistent skin lesions less extensive. Clinical case, possible pathogenesis and therapeutic strategies are discussed.
