A clinical trial to compare the occurrence (or incidence) of the most common fair skin cancer in solid organ transplant recipients (squamous cell carcinoma) and its preliminary stage (actinic keratoses) in two different groups: One group is treated with a fixed combination of a cream followed by exposure to red light and the other group receives liquid nitrogen (cryotherapy) as lesion-directed therapy.
