Pigmented Contact Dermatitis Due to After Shave Lotion / 대한피부과학회지

ABSTRACT

Pigmented contact dermatitis is characterized by a dark brown pigmentation that results from repeated exposure to small amounts of contact allergen. Histopathologic findings are liquefactive degeneration of the basal layer cells and melanophages in the upper dermis. We report a case of a 73-year-old man with dark brownish mottled hyperpigmented patches on the both cheeks and forehead. Patch tests were positive to isoeugenol, benzyl salicylate and after shave lotion. After shave lotion that the patient used maybe contain these fragrances. Improvement was seen 3 months after ceasing the use of after shave lotion.
