[Neuropathy of the chin associated with neoplasms. Presentation of 5 cases and a review of the literature]. / Neuropatía mentoniana asociada a neoplasia. Presentación de cinco casos y revisión de la literatura.

ABSTRACT

Mental neuropathy is a paraneoplastic syndrome characterized by hypoesthesia or anesthesia in the area of mental nerve inervation. Its ethyology is not well known, and in some cases would be secondary to metastasis in the mandible, meningeal carcinomatosis or infiltration of the ganglion of Gasser. We report five new cases; three of them we have studied the presence of circulating antibodies against nervous tissue of ganglion of Gasser, and it was negative in all of them. Likewise we have reviewed the literature.
