Squamous cell carcinoma (SCC) is usually a mild form of skin cancer that can be very dangerous in certain situations.
This patient noticed a sudden growth of this crusted red nodule on a frequently sun exposed area of his arm that resembled an SCC. Of note, the patient had a kidney transplant several years before. To prevent rejection of his transplanted kidney, the patient takes several medications that suppress his immune system. These immunosuppressive medications can make skin cancers more frequent and aggressive. As a result, anyone using these medications, even for other conditions, has a higher chance of dying from skin cancer. Patients on these medications have to be careful with the sun and should be followed closely by a dermatologist.
