Dilated Pore of Winer

Overview

A dilated pore of Winer is a benign, common skin lesion that presents as a single, enlarged, dilated follicular opening (pore) filled with a keratinous plug. It is essentially a large, solitary comedo (blackhead) and is considered a type of benign follicular hamartoma. It most commonly occurs on the face of older adults and is entirely harmless.

Key Symptoms

Single, prominent, enlarged pore on the skin surface
Dark keratinous plug filling the dilated opening (resembles a large blackhead)
Typically 1-8 mm in diameter
Most common on the face, especially the nose, cheeks, or forehead
Asymptomatic — no pain, itching, or tenderness
Slowly enlarging over time if untreated

Affected Areas

Face (most common), Nose, Cheeks, Forehead, Neck

Care Instructions

No treatment is required as the lesion is completely benign.
Extraction of the keratinous plug with a comedone extractor can be performed for cosmetic reasons.
Punch excision provides definitive removal with minimal scarring.
Recurrence may occur if the pore lining is not completely removed.
Topical retinoids may help reduce the size of the plug.
See a dermatologist if the lesion changes or if there is diagnostic uncertainty.
