Winer's dilated pore of the eyelid.

A 71-year-old woman had a whitish mass of the outer right lower eyelid with an eccentric pore plugged with keratin. Histopathologic evaluation disclosed an epidermoid cyst that opened widely to the surface and was filled with flaky keratin. The wall displayed a proliferation of rete ridge-type structures that projected in the surrounding dermis. The lesion was diagnosed as a dilated pore of Winer and has not recurred after simple excision.
