Pseudopelade of Brocq

  Pseudopelade of Brocq (PPB) is a rare, idiopathic, slowly progressive hair disorder, resulting in cicatricial alopecia. It typically presents in Caucasian adult patients as small, smooth, flesh‐toned and slightly depressed alopecic patches with irregular outlines. It primarily involves the parietal and vertex portions of the scalp with a chronic prolonged course. Controversial opinions still exist as to whether PPB is a single entity or an end stage of several cicatricial alopecic disorders. A practical approach to diagnosis of PPB and therapeutic update are discussed in this review.
