Acquired dermal melanocytosis – http://id.who.int/icd/entity/1913625538

Acquired dermal melanocytosis is a pigmentary disorder which typically presents in young adult women of Asian origin as bilateral pigmented macules on the face (Hori naevi). They resemble naevus of Ota but do not involve mucosal surfaces. Oestrogens and exposure to UV have been implicated. The condition may however affect other sites such as the hands and lower extremities.
