Squamous cell carcinomas in organ transplant recipients. Comparison of histopathological and clinical features of squamous cell carcinoma in patients after organ transplantation to immunocompetent patients.

The occurrence of neoplasms is one of the most common complications and second most frequent cause of death in organ transplant recipients (OTRs). The most frequently occurring neoplasms are skin cancers, predominantly squamous cell carcinoma (SCC). However, the ratio between SCC and basal cell carcinoma (BCC) in OTRs differs in several studies depending on the follow-up time, country, environment and other factors.
