Non-specific scarring form of alopecia of the scalp generally seen in adults. It is characterized by multiple asymptomatic, small, round, oval or irregularly shaped hairless cicatricial patches. Affected areas are ivory-white or slightly pink and atrophic. It is generally regarded as a clinical syndrome which may be the end result of any one of a number of different pathological processes. Many instances of this disorder may be associated with lichen planopilaris, lupus erythematosus, morphea, and folliculitis decalvans.
