Multiple vulvar dilated pores in a postmenopausal woman

Winer’s dilated pore is an infrequent appendageal tumor characterized by a giant comedone on the face,neck,and upper trunk in adults. we report a 57-year-old woman who developed multiple asymptomatic black papules on both labia majora. histopathology showed grouped dilated follicles lined by keratinizing squamous epithelium in the superficial dermis. the superficial lining epithelium and interfollicular epidermis were atrophic,while the deep epithelium showed mild proliferation and melanin pigmentation with a few short projections extending into the surrounding dermis. we diagnosed multiple winer’s dilated pores based on late-onset lesions and pathological features. this patient may represent the first case of multiple vulvar winer’s dilated pores. we suggest that electrocautery may be effective for treating this type of superficial entity. © 2017 by anais brasileiros de dermatologia.
