Background  Organ transplant recipients have an increased risk of skin cancers. A specialist dermatology clinic for renal transplant recipients (RTRs) was established in 2005.

Objectives  To analyse the type and incidence of skin cancers in prevalent patients in the West of Scotland after renal transplant, and to analyse the impact of the time since transplant and the immunosuppression regimen.

Methods  Skin cancer data for RTRs attending the transplant dermatology clinic over a 38-month period were collected and recorded in the West of Scotland electronic renal patient record. Skin cancer data were intrinsically linked to each individual’s transplant and immunosuppression data.

Results  Overall, 610 patients attended. The median follow-up time from the date of first transplant was 10 years. Ninety-three patients (15·2%) had experienced a total of 368 skin cancers since transplant, and the prevalence increased with time since transplant. Basal cell carcinomas (BCCs) occurred in 74 patients (12·1%) and squamous cell carcinomas (SCCs) in 42 patients (6·9%). Three patients (0·5%) had experienced a melanoma. The SCC:BCC ratio was 0·7. Survival analysis showed significant reduction in the time to develop skin cancer in patients transplanted from 1995 onwards (< 0·0001) and in patients who had been on triple immunosuppressant therapy at 1 year after transplant, compared with dual therapy (< 0·0001).

Conclusions  This is the first study of skin cancer in prevalent Scottish RTRs. The incidence of skin cancer is high and appears to have a direct relationship to the overall burden of immunosuppression. The SCC:BCC ratio, which is lower than reports from other centres, deserves further scrutiny.
