A case of a 30 year-old man with numerous, pink to whitish, 1-2 mm, cystic lesions, located exclusively on the face and helices in symmetrical distribution is reported. Microscopic examination of serial sections of two biopsies disclosed dermal cystic cavities with vellus hair shafts into the lumen. The cyst wall was connected to rudimentary pilar structures. This picture is typical of eruptive vellus hair cysts (EVHC). Facial variant of this dermatosis is reported only in two cases in the literature. Histogenesis and differential diagnosis are discussed.

Abstract
A case of a 30 year-old man with numerous, pink to whitish, 1-2 mm, cystic lesions, located exclusively on the face and helices in symmetrical distribution is reported. Microscopic examination of serial sections of two biopsies disclosed dermal cystic cavities with vellus hair shafts into the lumen. The cyst wall was connected to rudimentary pilar structures. This picture is typical of eruptive vellus hair cysts (EVHC). Facial variant of this dermatosis is reported only in two cases in the literature. Histogenesis and differential diagnosis are discussed.File in questo prodotto:
