Lichen amyloidosis of the scalp and forehead.

Lichen amyloidosis is a subtype of primary localized cutaneous amyloidosis (PLCA), which presents as discrete, firm, closely-set 1-3mm, dome-shapedbrown papules commonly involving the anterior aspect of shins and extensor surfaces of forearms. We present a case of an otherwise healthy man in his 30s with solitary facial involvement of lichen amyloidosis, which is very uncommon.
