Core Tip

Core Tip: Lichen amyloidosis (LA) is a chronic, severely pruritic skin disease, which is the most common subtype of primary cutaneous amyloidosis characterized by deposition of amyloid protein on the skin without visceral involvement. The treatment of LA has been considered difficult, with high relapse rates. In this article, we present four cases of LA associated with atopic dermatitis (AD) treated with dupilumab who achieved remarkable results. Our observations suggested that dupilumab may shed light on the systematic treatment of refractory LA patients with AD.
