Rare skin tumours in organ transplant recipients

Transplantation improves overall survival of patients and it also improves their quality of life. The transplanted organ can maintain its proper function for many years thanks to modern immunosuppressive therapy but unfortunately, a growing number of complications of such treatment is being reported. Skin cancer is the most frequently reported type of cancer in patients after organ transplantation. The most common tumours observed in kidney transplant recipients are squamous cell carcinoma and basal cell carcinoma, which account for 90% of skin cancer cases. Adnexal tumours are hardly observed in general population, however they are more likely to occur in organ transplant recipients. In this manuscript we would like to focus on rare cancers in organ transplant recipients.
