Cutaneous groin lesions.

The groin, the lowest portion of the abdominal wall near the junction with the thigh, is the site of a disproportionately large amount of dermatologic disease. Because of its close proximity to the genitalia it is the site of numerous sexually transmitted disorders. Maceration of the skin, which can occur quite readily in this area as the result of heat, perspiration, friction, and irritation, is a second factor enabling many cutaneous diseases to begin and to fluorish. This paper discusses the major cutaneous groin disorders with particular emphasis on practical diagnostic and therapeutic features.
