Abstract

Eruptive vellus hair cysts are asymptomatic, flesh-colored- to-bluish, 1-to-4 mm-sized papules that are usually located on the chest and extremities of children and young adults. Histologically, small cysts are observed in the mid-dermis and these cysts contain multiple hair shafts and keratinous materials. We report here on a case of eruptive vellus hair cysts that developed on a rare site, the labium major.
