• Melasnna
• Acquired bilateral melanosis of the neck

Pigmentary changes in Asians are larger problems and more important features of aging than wrinkles. Melasrna is a commonly observed epidermal hypermelanosis of the face in Asians. The altered dermal structures and impaired basement membrane are thought to have an influence on the development of epidermal hyperpigmentation of melasma. Dermal hyperpigmentary diseases are particularly common in Asians. Acquired bilateral melanosis of the neck is a characteristic dermal melanotic condition primarily of the neck in peri-menopausal women. It is characterized by marked accumulation of dermal pigment with perivascular lymphocytic infiltration. The cases seem to represent a continuum of Riehl%26apos;s melanosis. Subclinical injury or inflammation may playa role as possible causative factors for the development of the pigmentation.
