摘要： Tattoos are common around the world, although not without risk. Tattooing may result in several complications, including infections, foreign-body and sarcoidal granulomatous reactions, delayed-type hypersensitivity reactions, keloid formation, pseudolymphomas, pseudoepitheliomatous hyperplasia, as well as koebnerization and pathergy of associated pre-existing skin diseases. Tattoos may even potentiate cutaneous neoplasms including benign growths, such as seborrheic keratoses, and malignant neoplasms, such as nonmelanoma skin cancers (NMSCs) and malignant melanoma. Although the mechanism underlying neoplasia due to tattoos is poorly understood, it has been suggested that trauma from the procedure itself, the carcinogenic potential of the dyes, or chronic inflammation could play a role. In this study, we present a case of multiple NMSCs developing within the red pigmented area of a tattoo after repeated laser tattoo removal treatments.
