title: Keratoacanthoma accompanied by multiple lung squamous cell carcinomas developing in a renal transplant recipient.
abstract: Keratoacanthoma (KA) is a benign keratinocytic neoplasm that spontaneously regresses after 3-6 months and shares features with well-differentiated squamous cell carcinoma (SCC). An increased incidence of both KA and non-melanoma skin tumor, including SCC, is seen among immunosuppressed, organ-transplant recipients. In this report we describe a case of KA accompanied by multiple lung SCCs developing in a renal transplant recipient.
