Pseudopelade of Brocq (PPB) is a type of scarring alopecia for which the cause is not known. It leads to the destruction of hair follicle stem cells which in turn leads to a permanent type of hair loss. Hair regrowth does not occur.
There are several clinical variants and so not all patients with PPB have the same appearance. Dr Vera Price, Professor Emeritus at UCSF in San Francisco, California termed this form shown in the photo as the "holly berry" form as it resembles the grouped holly berries of a holiday Christmas wreath. Small 4-8 mm white circular areas of hair loss are seen. It is easily confused with alopecia areata at first glance. However, alopecia areata of this small size would most likely respond to steroid injections. PPB does not regrow hair with steroid injections.
