A single plexiform neurofibroma or two of any type are considered diagnostic of neurofibromatosis type 1 (NF). Plexiform neurofibromas are congenital and pathognomonic for NF-1. It is uncommon for an individual with NF-1 to have more than one plexiform neurofibroma. We, herewith, report a 38 year old man with NF-1, having exceptionally large bilateral plexiform neurofibromas involving both lower limbs.
