Perifolliculitis capitis abscedens et suffodiens is a rare infection of the scalp. It was first described as an entity under this name in 1907 by Hoffmann.1 The first case in this country was reported in 1921 by Wise and Parkhurst2 as "a rare form of suppurative and cicatrizing disease of the scalp." Since then little more than two dozen cases have been reported or presented, the majority of them in Negroes. Some of the observers believe that the affection is related to acne conglobata. There is undoubtedly some resemblance, and as in acne conglobata etiology and pathogenesis remain unexplained. Pyogenous cocci have been demonstrated in some cases and were absent in others. The morphologic picture is one of more or less insidiously growing and spreading nodules, infiltrations, abscesses, and sinuses, which undermine large areas of the scalp and lead to scar formation and loss of hair.
