Intertrigo is inflammation of approximating skin surfaces predominantly found in the perineum and neck creases, though any intertriginous area may be involved. Intertrigo is exacerbated by any condition that increases heat, wetness, and friction of opposing skin surfaces. Intertrigo is often complicated by superficial skin infection with yeast or bacteria. Intertrigo caused by cutaneous infection with Streptococcus can be seen at the neck, axillae, inguinal fold, or perianal regions.
