[The Winer dilated pore].
Dilated pore (Winer) is a not uncommon adnexal benign tumor with follicular differentiation. Clinically the lesion looks like a giant comedo, usually located on the facial area of the elderly. Due to annular elevation of the borders, differential diagnosis needs to be made with basal cell epithelioma and senile sebaceous adenoma. The histology shows a typical infundibular dilatation with subinfundibular atrophy of hair structures. The authors report two typical cases of this badly known but not infrequent lesions.
