Pigmented neurofibroma (PNF) is a rare cutaneous tumor that has been observed in patients with or without neurofibromatosis (NF). This tumor is histologically characterized by the coexistence of scattered melanin‐laden cells and benign spindle cells with neural differentiations. Hypertrichosis is the excessive growth of hair on non‐androgen‐dependent areas of the body. It has been reported that hypertrichosis may sometimes overlie a neurofibroma. We highlight a case of PNF with hypertrichosis on a 17‐year‐old woman with no associated NF. We also discuss the possible underlying pathogenic mechanism of a localized hypertrichosis in PNF patients.
