While previously considered benign lesions, keratoacanthomas are now believed by many to be low grade squamous cell carcinomas.[1] These lesions typically exhibit a rapid growth pattern and sometimes involute spontaneously. This lesion arose over a period of weeks. Note the classic dome-shaped nodule with elevated, rolled margins and a central keratin-filled crater. Note, the darkened coloration of the upper lid is a permanent eyeliner tattoo.
