Several forms have been described: cutaneous neurofibromas (both localised and diffuse types), intraneural neurofibromas (localised and plexiform), massive soft tissue neurofibromas (solitary or multiple), and sporadic neurofibromas or those associated with neurofibromatosis-1 (NF-1) [1, 2]. The gene discussed is NF1; the disease is plexiform neurofibroma.
