InHicks [ 5 ] presented four additional cases of amilkide on the concha of the ear, which appeared clinically and histologically identical to those previously reported by Sanchez. Physical examination revealed a rippled hyperpigmented rectangular plaque on the upper back, as well as monomorphous shiny brown mm papules in the conchal bowl and on the scapha of the right ear Fig. In four cases of smooth papules on the aural conchae were reported by Sanchez [ 4 ].
Physical exam was remarkable for bilateral, symmetrical brown scaly mm monomorphous papules mainly on the conchal bowls Fig. Previous article Next article.

Lichen amyloidosis is a rare chronic form of cutaneous amyloidosis see this terma skin disease characterized amiloidde the accumulation of amyloid deposits in the dermis, clinically characterized by the development of pruritic, often pigmented, hyperkeratotic papules on trunk and extremities, especially on the shins, and histologically by the deposition of amyloid or amyloid-like proteins in the papillary dermis.
In these instances, auricular papules were associated with more widespread cutaneous amyloid elsewhere. Primary localized cutaneous amyloidosis is, by definition, amyloid deposition limited to the skin and not associated with underlying systemic illness.
Review of systems was unremarkable and negative ailoide alopecia, arthralgia, oral sores, and photosensitivity.
