This disorder was first described by Charles-Eugène Quinquaud in 1888. He isolated bacteria from the hair follicles of affected patients and introduced them in rats, mice and rabbits, with no result. In 1905 it was then differentiated from other scarring alopecias and the name<unk> , that remains current, was introduced. About 11% of the occurrences of scarring alopecias are of this type. Men are more commonly affected than women and its appearance is usually between the late teens and middle adult years. According to studies in the United States, African Americans are more frequently affected than White Americans.
