title: Primary idiopathic pseudopelade of brocq: five case reports.
abstract: Pseudopelade of Brocq (PPB) is a rare, idiopathic self-limiting hair disorder resulting in progressive cicatricial alopecia primarily involving the parietal scalp and vertex. The general pathogenesis of scarring alopecias has been focused on theories of stem cell failure and sebaceous gland destruction. Acquired immunity, Borrelia infection and senescence of follicular stem cell reservoir plays suspected role. It classically presents as porcelain white hypopigmented and slightly depressed atrophic plaque. There is no standard treatment for PPB. Here, we present five cases which were labeled as primary idiopathic PPB, as on histopathology no specific changes of any cicatricial alopecia were seen.
