Abstract

Plexiform neurofibroma is considered to be pathognomic of neurofibromatosis type 1 (NF1). Herein we report a solitary plexiform neurofibroma which is not associated with NF1. A 61-year-old man presented with asymptomatic skin colored nodules on the medial side of his left great toe. No other abnormalities were found in his personal or family history. Clinically, the tumor was simulating the appearance of mucous cysts. Microscopically,it was a plexiform neurofibroma located in the dermis which seemed to originate from small superficial nerves. This case would seem to confirm that the superficial form of plexiform neurofibroma involving small nerves in the dermis or subcutis is not necessarily pathognomic for NF1.
