Psoriasis of the penis: Koebner reaction. Following oral genital exposure

Today, there is an apparent increase in oral genital activity among heterosexual groups not only in the United States but also globally. As a result, gonococcal pharyngitis was rediscovered, and primary syphilis of the oral cavity has been recognized with increasing frequency. In addition, physicians are seeing a wide variety of traumatic lesions of the genitals from "hickeys" of the labia to dental imprints and ulcerations of the glans penis. Our patient exhibits an interesting phenomenon recognized readily elsewhere on the skin but infrequently diagnosed on the glans penis.
