We present two patients with clinical diagnosis of Neurofibromatosis 1 (NF1), both of them without negative family history for the disease but with multiple café-au-lait spots and axillary or inguinal (skinfold) freckling. The female patient suffered osseous problems characterized by radium pseudoarthrosis and scoliosis and Lisch nodules. Male patient showed a left forehead mass present at birth, that caused proptosis, and whose histopathological study showed a plexiform neurofibroma. Both cases meet current diagnostic criteria of NFl. This studyCurrent diagnostic criteria of Neurofibromatosis 1 and Neurofibromatosis 2 in the context of these two cases.
