neu·ro·fi·bro·ma

(nū'rō-fī-brō'mă),

Neurofibromatosis type I is a disorder characterized by the presence of two or more of the following findings: six or more "cafe au lait" macules (> 5 mm in diameter in puberty and > 15 mm in postpuberty patients), two or more neurofibromas of any type or one plexiform, freckling in the axillary or inguinal regions, optic glioma, two or more "Lish" nodules, and a distinctive osseous lesion.
Moreover, patients and physicians fundamentally agree on which manifestations of NF1 are most important to treat, with MPNST, plexiform neurofibromas, and optic gliomas rated as top priorities for both groups.
Los neurofibromas a pesar de cursar generalmente con enfermedades hereditarias, pueden presentarse en personas sanas como masas incidentales especialmente en su forma solitaria, por lo cual conocer su origen biologico, manifestaciones clinicas, forma de diagnostico y tratamiento resultan de interes para el medico.
Patients with NF1 have an increased risk of developing tumors of the central and peripheral nervous system including plexiform neurofibromas (27%), optic gliomas (15-20%), pheochromocytomas (1%), malignant peripheral nerve sheath tumors (5%), and neurofibrosarcomas (6%).
