Pseudopelade of Brocq (PPB)

Example 2

For some patients with PPB, the affected areas are white and can appear rather "inactive" even when they are "active." For other patients, the affected areas take on a red/pink color that correlates with activity. In these cases, one can not usually be totally confident the condition is "quiet"(inactive) until the red color goes away and the areas turn to a white color.
