title: Keratoacanthoma recurrent after surgical excision.
abstract: A 62-year-old man developed a recurrent keratoacanthoma within two and a half weeks after grossly and microscopically complete removal of the primary tumor. X-irradiation of the recurrent lesion caused partial regression, and then intralesional injections of a suspension of triamicinolone caused final resolution of it. Although dermatologists generally practice partial destruction and surgeons almost always do total excision, neither method invariably cures this benign tumor, and repeated treatment may be necessary.
