Nonneoplastic cutaneous or mucosal complications are frequent in organ transplant recipients. In a systematic overview made in Leiden, 591 nonmalignant skin diseases were registered in 1768 (33%) organ transplant recipients followed over 13 years [1]. Smaller series reported that the prevalence of nonmalignant skin lesions in transplant recipients may range between 49% and 87% [2][3][4][5]. The lesions are mainly related to the prolonged use of immunosuppressive drugs, but an important contributing role may also be played by exposure to sunlight and viral infections. Although the pathogenesis of these lesions is often multifactorial, we will separate them into lesions caused by drugs and by infections.Drug-related skin lesions (Table 1) Calcium channel blockers can cause some cutaneous abnormalities, including photo-damage of the head and neck, teleangiectasia, and solar elastosis [6] as well as gingival hyperplasia [7]. However, most skin lesions in renal transplant recipients are caused by immunosuppressive drugs, in particular glucocorticoids and cyclosporine. An important consequence of the esthetic changes caused by these agents is a poor adherence to treatment which represents a major cause of graft failure [8].
GlucocorticoidsRenal transplant recipients given glucocorticoids may show a number of dermatological lesions which are related to the doses and the time of exposure of these agents. While the doses of glucocorticoids used in transplantation were very high in the recent past, the current immunosuppression is based on low doses of glucocorticoids and some units even treat transplant recipients with steroid-free regimens. As a consequence, the skin changes Keywords fungal infections, mucocutaneous lesions, transplant complications, transplantation and skin lesions.
