Perifollicular fibroma(PFF) is a rare cutaneous hamartoma that shows differ
entiation in the connective tissue sheath of the hair follicle. It may be s
ingle (congenital or acquired) or multiple (late onset). We report a 14-yea
r-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. (C
