Neoplastic trigeminal neuropathy: presentation of 7 cases.

Trigeminal neuropathy of neoplastic origin accounts for a small percentage of trigeminal neuropathies, though the prognosis may be very poor. It is important to discard neoplastic processes in patients with numbness of the trigeminal territory. We present 7 cases of trigeminal neuropathy secondary to tumors: in four cases there were antecedents of systemic neoplastic disease, while in the remaining three cases neuropathy was the first manifestation of the tumor.
