Most patients with dilated pore of Winer consult a dermatologist after many years of dealing with an unsightly, enlarged pore on the face. [5]

Patients with dilated pore of Winer usually have a past or present history of severe acne.

Patients report needing to repeatedly express a keratotic plug from the center of the dilated pore of Winer. The expression of this plug allows the further removal of caseous, white, soggy keratin from the deeper portion of the pore. Once the content of the dilated pore is expressed, a keratotic material similar to the original plug refills the pore within several weeks.


Physical Examination

A dilated pore of Winer usually appears as a solitary large comedo on the face, predominantly on the upper lip, cheek, or forehead. The lesion can also be found on the trunk, most commonly the back. A rare incidence involving external ear canal has also been reported. [6]

The skin surrounding the pore appears to be unchanged, with no inflammation or induration.



Manipulation of a dilated pore of Winer may lead to infection and scarring.
