[Skin pathology in kidney transplant recipients].

Since 1990, 82 unselected renal allograft recipients were evaluated in order to establish the incidence of cutaneous disorders. This pathology was related to the period of immunosuppression according to time of transplantation: 0-3 months; 3-12 months; 12-36 months and beyond 36 months. Most of them were on triple immunosuppression (cyclosporine A, azathioprine and prednisone)--(51); Twenty-two also associated anti-timocyte globulin five days after transplantation; 7 were on Azathioprine and Prednisone and two of them associated Cyclosporine with Prednisone.
