ABSTRACT

Eruptive vellus hair cysts are characterized by asymptomatic, skin colored to bluish, or brownish, 1-4mm sized, follicular papules and nodules located on mainly anterior chest, axilla, groin, and thigh. Histopathologic examination reveals cysts containing multiple vellus hairs and the laminated keratinous materials at dermis. We reported 2 cases of eruptive vellus hair cysts developed on the unusual sites, forehead and buttock, respectively.
