papules of the external ear. Micropapular hyalinosis of the external
ear with transepithelial elimination. Relation to primary localized
cutaneous amyloidosis. Ann Dermatol Venereol. 1984; 111 (10):913-7.
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.

Four cases
of a new entity characterized by papules that are smooth in surface
and unchanged in color on the aural conchae are reported.
Histologically they are characterized by sclerotic and hyalinized
masses within thickened dermis and by special stains and electron
microscopy are revealed to consist of altered collagen.
