[Collagenous papules of the external ear. Micropapular hyalinosis of the external ear with transepithelial elimination. Relation to primary localized cutaneous amyloidosis].
Sanchez has recently described a new entity characterized by the presence of papules bilaterally located on the aural pinnae. The four presented cases concerned women. Clinical picture of the disease is, without any doubt, unusual but "hyalin" masses are non-specific since they are similar to amyloidosis on account of thioflavine T positivity and microfilamentous aspect in electron microscopy. We reported at the Meeting of the French Dermatological Society (Toulouse, November 10, 1981) a very similar case under the name of "Hyalinose micro-papuleuse de la conque des oreilles avec élimination trans-épidermique". In the present paper we report this personal case, and we point out some original findings: pigmentary changes, trans-epidermal elimination of the hyalinized findings material and presence of an inflammatory process.
