I have made a personal observation that a dilated pore of Winer, on microscopic examination resembles a glass of red wine.
Over the years I have been telling the residents that the recognition of a dilated pore under the microscope (Figs. 1, 2, 3, and 4) is an easy one because it looks like a ‘wine glass’. Moreover, if the pore is filled with keratin, it may resemble a glass of red wine (Fig.5). Interestingly, the lesion was first described by a dermatologist named Dr. Louis H Winer 1. I am showing several photomicrographs of dilated pore to illustrate my observation.
