RESUMEN
Advancements in solid organ transplantation successfully extend the lives of thousands of patients annually. The tenet of organ stewardship aims to prevent the futile expenditure of scarce donor organs in patient populations with high mortality risk, to the detriment of potential recipients with greater predicted life expectancy. The development of skin cancer posttransplantation portends tremendous morbidity, adversely affecting quality of life for many transplant recipients. This special article, provided by of members of the International Transplant Skin Cancer Collaborative (ITSCC), will provide the transplant professional with a consensus opinion and recommendations as to an appropriate wait period pretransplantation for transplant candidates with a history of either cutaneous squamous cell carcinoma, malignant melanoma, or Merkel cell carcinoma.

This manuscript outlines estimated risk and clinical course of pretransplant MM, donor-transmitted MM and de novo MM posttransplantation and includes an analysis of risk factors for metastasis, data from clinical studies and current and proposed management. MM in situ and thin melanoma (<1 mm) in the transplant population has similar recurrence and survival estimates to those in the general population. A minimum wait time of 2 years prior to transplantation is suggested for MM with a Breslow depth <1 mm and no clinical evidence of metastasis. More advanced MM may adopt a more aggressive course in transplant recipients. Sentinel lymph node biopsy may be of additional prognostic benefit. Revision of immunosuppression in the management of de novo melanoma in collaboration with the transplant team should be considered. Larger studies utilizing uniform staging criteria or at minimum Breslow depth, are required to assess true risk and outcome of MM in the immunosuppressed transplant population. Emphasis remains on patient education and regular screening to provide early detection of MM.
