Plexiform Neurofibroma in a 16 year old boy

Plexiform Neurofibroma appeared at the age of 5 years, with little pain and itching at the site. Increase in size and weight of Plexifom was gradual with age. In this case the Plexiform developed on lower right arm. All over the body, the patient also showed other signs of NFl, Caf‚-au-lait spots [CLSs] and sessile neurofibroma. Freckles were seen in the arm pits and over the stomach skin. The Lisch nodules were also present in the eyes of the subject. Pedigree of the patient confirms that the case is familial one where his mother had NFl but no Plexiform. Biopsy confirms that neurofibromatosis tumors were benign
