Abstract (English):	Amyloid lichen is a primary presentation of cutaneous amyloidosis. It is characterized by the appearance of hyperkeratotic papules that converge and form skin-colored or hyperpigmented, pruritic plaques located in the lower limbs, with a predominance in pretibial areas. We present the case of a 58-year-old male patient with typical symptoms of amyloid lichen. The histopathological study confirmed the diagnosis. The therapeutic regimen used with narrowband UVB phototherapy achieved, in the short term, remission of the lesions. Although few studies define the exact mechanisms of action of narrowband UVB phototherapy in this pathology, it could be considered a safe and viable therapeutic option for patients with amyloid lichen.

Abstract (Spanish):	El liquen amiloide es una presentación primaria de amiloidosis cutánea. Se caracteriza por la aparición de pápulas hiperqueratósicas que confluyen y forman placas del color de la piel o hiperpigmentadas, pruriginosas, localizadas en los miembros inferiores, con predominio en las áreas pretibiales. Se presenta el caso de un paciente masculino de 58 años, con clínica típica de liquen amiloide. El estudio histopatológico confirmó el diagnóstico. El régimen terapéutico utilizado con fototerapia UVB de banda estrecha logró, a corto plazo, la remisión de las lesiones. Aunque son pocos los estudios que definen los mecanismos de acción exacta de la fototerapia UVB de banda estrecha en esta patología, podría considerarse una opción terapéutica segura y viable para los pacientes con liquen amiloide.
