Lichen amyloidosis presenting as a papular pruritus syndrome in a human-immunodeficiency-virus-infected man

A human-immunodeficiency-virus (HIV)-positive man presented with pruritic erythematous and flesh-colored papules on his arms and trunk of 1 year's duration. The lesions had previously been treated with oral ketoconazole and topical emollients with no improvement. Microscopic evaluation of lesional skin from his left forearm showed lichen amyloidosis. The patient was started on ultraviolet B phototherapy which he received for 2 weeks without improvement. Lichen amyloidosis should be added to the differential diagnosis of papular pruritus syndrome in HIV-positive individuals.
