    Abstract:
    OBJECTIVE: To analyze the dermatologic lesions and possible effects of immunosuppression treatment and p53 gene mutations on dermatologic findings in renal transplant recipients. MATERIALS AND METHODS: The study included 163 renal transplant recipients. After dermatologic examination, cultures, and histopathologic and genetic analyses were performed. A single-strand conformation polymorphism technique was used to analyze p53 gene mutations. Patients were categorized into 3 groups according to time since the transplantation procedure. Results were analyzed using the χ(2) test, using a software program (SPSS version 13.0; SPSS, Inc, Chicago, Illinois). RESULTS: Mean (SD) age of the 163 transplant recipients (65 women and 98 men) was 40 (11) years, and posttransplantation follow-up was 65 (55) months. The most frequently observed drug-related lesion was hypertrichosis, in 46 of 150 patients. Of 115 lesions, the most commonly observed were verruca vulgaris (n = 34) from viruses, and pityriasis versicolor (n = 21) from superficial fungal infections. Of the total group, 20 patients (12.2%) were mutation carriers. Compared with the entire cohort, the group with premalignant lesions demonstrated more p53 mutations (11% vs 50%; P = .004). Patients given cyclosporine therapy exhibited more premalignant or malignant cutaneous lesions compared with patients who received other agents (P = .03). CONCLUSION: Patients carrying p53 mutations developed a malignant lesion in the late posttransplantation period, which suggests the importance of prediction of risk.
