Perifollicular fibroma(PFF) is a rare cutaneous hamartoma that shows differentiation in the connective tissue sheath of the hair follicle. It may be single (congenital or acquired) or multiple (late onset). We report a 14- year-old Korean boy with a congenital solitary PFF on the face, which supports the nevoid concept of origin rather than a reactive response to injury.
