Dilated Pore Of Winer

A dilated pore of Winer (DP), first described by Louis H. Winer in 1954, is a commonly occurring benign adnexal tumor of follicular differentiation. Although most commonly located on the head and neck, a dilated pore of Winer can also be found on the trunk of middle-aged and elderly individuals. These clinically present as an asymptomatic, solitary, enlarged pore with a keratin plug and normal surrounding skin. Prognosis is excellent for these lesions as they are benign and typically do not require any further testing or work-up. Histopathologic evaluation can confirm the diagnosis in uncertain cases. Removal can be performed via excision for cosmetic purposes.
