Macular amyloidosis: treatment with ultraviolet B

Macular amyloidosis, a variant of lichen amyloidosus, is an uncommon cutaneous eruption that presents with moderate to severe pruritus associated with areas of hyperpigmentation. Effective modalities for the treatment of this condition have been lacking. A case of macular amyloidosis is reported in which successful management of pruritus was obtained using ultraviolet B (UVB) therapy. Mechanisms of UVB action in this condition are discussed.
