Several cutaneous disorders may occur in organ transplant recipients. We examined the incidence and the clinical spectrum of cutaneous manifestations among kidney transplant recipients. One hundred nine patients (70 males and 39 females), aged 19 to 69 years (mean: 42.5 years), were consecutively examined as outpatients between June 2000 and August 2004. The mean interval after kidney transplantation was 61 months (range: 2 to 120 months). The immunosuppressive regimen consisted of combinations including cyclosporine, systemic corticosteroids, azathioprine, tacrolimus, mycophenolate mofetil, antivirals, and antibiotics. Ninety-one cutaneous manifestations were identified in 60 of 109 (55.0%) kidney transplant patients over a 4-year period. Sixteen (17.5%) cutaneous viral infections identified in 11 patients (10.0%) included verruca vulgaris (n = 9), herpes zoster (n = 5) and herpes simplex (n = 2). Thirteen (11.9%) patients showed 19 (20.8%) superficial fungal infections, consisting of dermatophytosis (n = 6), onycomycosis (n = 6), pityriasis versicolor (n = 5) and mucocutaneous candidiasis (n = 2). Twenty (22%) nonmelanoma skin cancers were identified in seven (6.4%) patients, six basal cell carcinomas (BCC) in four patients, two squamous cell carcinomas (SCC) in two patients, and 11 BCCs in addition to one SCC in one patient. Twenty-six (23.8%) patients developed 32 (35.4%) drug-related manifestations, including acneiform eruption (n = 14), gingival hypertrophy (n = 6), hypertrichosis (n = 6), ecchymosis (n = 3), and plantar hyperkeratosis (n = 3). In addition, psoriasis and seborrheic dermatitis, which had been diagnosed before kidney transplantation, were observed in five and three patients, respectively. Our results emphasize the importance of dermatologic examinations and monitoring kidney transplant recipients to obtain an early diagnosis and treatment of cutaneous manifestations.
