Differential DiagnosisHistory:
Lichen amyloidosis is characterized by closely set, discrete, brown-red papules that often show some scaling and are most commonly located on the legs, especially the shins, although they may occur elsewhere. Through the coalescence of papules, plaques may form. These plaques often have verrucous surfaces and then resemble hypertrophic lichen planus or lichen simplex chronicus. Usually the lesions of lichen amyloidosis itch severely. Here is a good example of lichen amyloidosis on the back.
