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.[1]  Neither an effective treatment nor cure is currently available.[2][3]
