Maria's tip; for all the cases of Colloid milium in the ears , do congo red to exclude amyloidosis.

Primary amyloidosis of the externar ear. Immunohistochemistry with cytokeratin (CK5 or 34BE12) would be more specific, since basofilic degenerated collagen can be positive for Congo red.

I think there two sources for the hyaline material that fills the superficial dermis. Civatte bodies from degenerated keratinocytes can be recognized as round eosinophilic bodies into both epidermis and hyaline material. Sun-damaged elastic fibers appear as fissured basophilic masses.
I favor actinic amyloidosis / lichen amyloidosis of the auricular concha.

This is most likely auricular amyloidosis.
