Standard hematoxylin and eosin preparation displays a severe follicular epithelial inflammatory response, which may result in follicular distention and rupture. The pilar canal is filled with a dense polymorphonuclear leukocytic infiltrate, often accompanied by a brisk perifollicular lymphocytic infiltration. Both the epidermis and the infected apocrine glands remain intact.
