文献摘要

Riehl’s melanosis is characterized by facial hyperpigmentation (1,2). It has been associated mostly with pigmented allergic contact dermatitis from ingredients of cosmetics, brilliant lake red, sudan III, and other specific substances in cosmetics (1,2). Occurrences decreased dramatically after these components were eliminated from cosmetics (2). Recent cases have not been caused by exposure to chemicals (2–4). It is now believed that Riehl’s melanosis is a continuum of lichenoid immune reactions and may be caused by intrinsic as well as extrinsic factors (2–4). Here, we show a case of a facial melanosis with negative patch test reactions to the cosmetics used by the patient. Intense pulsed light (IPL) has the broad range of 500–1200 nm. We applied IPL therapy to the patient because melanin granules are distributed in both epidermis and upper dermis. The affected lesions were noticeably improved by the treatment with IPL.dth_1
