Question: What is (are) Pseudopelade of Brocq ?
Answer: Pseudopelade of Brocq (PBB) is a slowly progressive, chronic condition characterized by scarring hair loss (cicatricial alopecia). There exists some controversy as to whether PBB is a distinct condition or the common final stage or variant of several different forms of scarring alopecias such as discoid lupus erythematosus (DLE) or lichen planopilaris (LPP). Some have suggested abandoning the use of the term pseudopelade of Brocq while others think that the term should be strictly used to describe patients that follow the pattern of hair loss described by Brocq et al.(i.e., multiple, small, discrete, asymmetrical, smooth, soft, flesh-colored or white patches of hair loss with little, if any, inflammation). Although the exact cause of PBB has not been identified, it is believed to be an autoimmune disease. Some individuals with PBB have been found to have Borrelia burgdorferi, the bacterium that causes Lyme disease. Neither an effective treatment nor cure is currently available.

Question: What are the treatments for Pseudopelade of Brocq ?
Answer: Is there treatment or a cure for pseudopelade of Brocq? Neither an effective treatment nor cure has been identified for pseudopelade of Brocq. Unfortunately, even when treatment relieves the symptoms and signs, the progression of hair loss may continue. The choice of treatment prescribed varies from person to person and depends mainly on the activity, extent of the disease and patient's tolerance to the treatment. Various forms of corticosteroids have been tried, including injections or skin lotions or creams. Surgery such as hair transplant or scalp reduction might be considered in patients whose condition has remained stable for two or more years.
