Clinical resolution of generalized lichen amyloidosis with dupilumab: a new alternative therapy

Lichen amyloidosis is a subtype of primary localized cutaneous amyloidosis characterized by deposition of amyloid protein in the skin without visceral involvement. Although it is usually limited to localized areas of the body, it rarely can present in a generalized fashion and is severely pruritic. The limited form is treated with skin directed therapies such as topical or intralesional corticosteroids or topical tacrolimus but the generalized type is more difficult to treat. We present a patient with generalized primary cutaneous lichen amyloidosis successfully treated with dupilumab.
