Cutaneous manifestations of renal transplantation in a New Zealand population.

AIM

To document the skin manifestations of renal transplant recipients.

METHODS

The findings in 52 patients (27 males; mean age 43.5 yr; range 22-74 yr; SD 12.0) with a stable renal transplant for a mean of 115.6 mth (range 3-258; SD 70.6). Thirty seven patients were on prednisone and azathioprine and 18 on prednisone, azathioprine and cyclosporin.

RESULTS

Including prior observations, 48 cutaneous malignancies were identified in nine patients, with the ratio of squamous cell to basal cell carcinoma being 1.2:1. No metastases were detected. Actinic keratoses were present in 20 patients and tended to be multiple and present on sun exposed skin. A wide range of nonneoplastic lesions was documented, including warts in 75%. Human papillomavirus was isolated from 43% of warts.

CONCLUSIONS

Renal transplant recipients require regular skin examination. Patients with high recreational or work related sun exposure prior to, or after transplantation, and those who have had a previous skin malignancy, should be identified as high risk patients for skin cancer and have regular dermatological follow up.
