A women developed airborne pigmented contact dermatitis due to musk ambrette in incense. Patch testing confirmed the diagnosis. Since olden times, people in Japan have burnt incense when they worshipped their ancestors. Recently, it has been in fashion to enjoy perfumes and people may burn incense all day long every day. Our patient burnt 2 kinds of incense every day for about 5 years.
