title: Successful treatment of lichen amyloidosis with combined bath PUVA photochemotherapy and oral acitretin.
abstract: Lichen amyloidosis (LA) is a chronic, pruritic skin disorder characterized by brownish-grey papules on extensor surfaces of legs and rarely on the trunk. Thioflavin T-positive amyloid deposits are found in the papillary dermis of affected skin, which is the only organ involved. A variety of therapeutic regimens for lichen amyloidosis have been described; however, in many cases with only limited effect. We report on two patients with lichen amyloidosis with typical clinical symptoms not responding to local treatment. A combined regimen with bath psoralen ultraviolet A (PUVA) and oral acitretin was initiated, resulting in nearly complete resolution of the papules and impressive relief from the severe pruritus. The beneficial response has persisted for 8 months. The suggested combined therapy with bath PUVA photochemotherapy and oral acitretin represents an efficacious and practical treatment modality for lichen amyloidosis with long-lasting effects.
