  Squamous cell carcinoma - Wikipedia, the free encyclopedia
In medicine, squamous cell carcinoma is a form of cancer of the carcinoma type that may occur in many different organs, including the skin, the esophagus, the lungs, and the cervix.
Squamous cell carcinomas account for about 20% of non-melanoma skin cancers, (with basal cell carcinomas accounting for about 80%), but are clinically more significant because of their ability to metastasize.
Squamous cell carcinoma is usually developed in the epithelial layer of the skin and sometimes in different mucous membranes of the body.

 Squamous Cell Carcinoma in Solid-Organ Transplantation
This review article discusses the main etiologic theories of squamous cell carcinoma, characteristics of skin cancer in the immunosuppressed patient, differences in skin cancer amongst three types of solid-organ transplantation (kidney, heart, and liver), and established and new treatments.
However, the incidence of SCC in transplant recipients is 40 to 250 times that of the general population, whereas the incidence of BCC is 10 times greater in transplant patients.[55,69] This results in a reversal of the BCC/SCC ratio.
SCCs in transplant patients are much more aggressive and deadly.[78,79] They tend to recur locally even after surgical excision.[80] Cancer that spread to lymph nodes occurred in 5.8% of patients.
