title: Fungal skin infections in organ transplant recipients.
abstract: Transplantation is now currently and increasingly performed for the treatment of various acute and chronic diseases. Today the kidney, heart, lung, heart-lung, liver, pancreas, kidney-pancreas, small bowel and bone marrow are being transplanted. The immunological status of patients receiving such transplants exposes them to the risk of developing bacterial, viral and fungal infections. The etiological agents of mycotic diseases involving the skin of transplant recipients range from the common dermatophytes through yeasts such as Candida spp., Malassezia spp. and dimorphic fungi to the emerging molds Fusarium spp. and Pseudallescheria boydii. The very wide spectrum of fungi causing cutaneous disease produces equally varied clinical aspects. Lesions may be typical, but are very often aspecific or ambiguous. Cutaneous lesions may be the sign of a trivial mycotic disease or the marker of a disseminated, potentially lethal fungal illness, so great attention should be given to their early recognition. Cutaneous manifestations due to Candida spp., Aspergillus spp., dematiaceous fungi and Pityrosporum folliculitis are usually observed early after transplant, cryptococcosis more than 6 months later, while the frequency of dermatophytoses increases as time goes by. Coccidioides immitis, Histoplasma capsulatum and Blastomyces dermatitidis may appear any time after transplantation. The management of the more severe forms of cutaneous mycosis in transplant recipients is difficult. Besides the fact that early recognition is not easy, there are also problems regarding the effectiveness and the toxicity of the therapy and drug-drug interactions. Prophylactic measures to avoid fungal contamination must be performed during hospitalization; patients should be taught how to avoid contamination, not only during the first period after transplantation, when high dosage immunosuppressive drugs are given, but also later when a normal lifestyle is resumed.
