Perianal contact dermatitis caused by nail lacquer allergy

image Allergy to nail cosmetics is relatively infrequent compared with other cosmetics. Allergic contact dermatitis from nail lacquer typically affects the eyelids, cheeks, sides of the neck, hands and periungual areas, and less frequently another areas. image We report on a patient who developed nail lacquer-related allergic contact dermatitis in an infrequent location, namely the perianal area. image A patient with perianal and eyelid pruritus and dermatitis was patch tested with the TRUE tests, cosmetic series, personal cosmetics, plastic and glue series, and personal nail lacquers. image A +2 positive allergic response was observed at the sites of the toluenesulfonamide-formaldehyde resin and at the sites the patientʹs nail lacquers at days 2 and 4. image Nail lacquer allergy may be observed at distant sites, and the perianal area may be involved more frequently than was previously thought.
