Increased incidence of cutaneous melanoma in organ transplant recipients based on a single-centre longitudinal study in Rome, Italy.

Several studies have shown a two- to five-fold increased risk of melanoma in organ transplant recipients (OTRs) due to chronic immunosuppression [1]. The reported standardized incidence ratio of melanoma in OTRs ranges from slightly above 1 [2] to 8.0 [3]. It is difficult to draw conclusions on the true relative risk of melanoma in OTRs because some studies reported only case series [4], while others analysed large data sets that were not designed for this purpose [5]. Here, we report the estimated [...]
