Introduction to the expansion hole

The dilated pore (dilatedpore) was first reported by Winer in 1954. It occurs in the face, usually in a single hair, with an enlarged pore or a large acne-like appearance. Histopathology: The hair follicle funnel was obviously enlarged, and the epidermis lining of the opening was atrophied, but the epidermis was thickened in the deeper cystic cavity, and many epidermal processes and irregular mild hyperplasia protruded into the surrounding interstitium. Surgical resection or electrocautery treatment.
