Resumen

LOBOS M, ADRIANA; CARDEMIL M, FELIPE  y  VILLAGRAN R, DIEGO. Facial nerve Schwannoma resembling a parotid tumor: Case report. Rev Chil Cir [online]. 2009, vol.61, n.6, pp.556-559. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262009000600012.

Facial nerve Schwannomas are benign tumors that originate from Schwann cells, with a slow and predictable growth, and that are generally asymptomatic. Only 9% of these tumors are located in the intraparotid segment of the facial nerve. We report a 26 years old female presenting with a mass in the left parotid region lasting four months. The patient was subjected to a parotidectomy. During surgery, an encapsulated tumor whose origin was in the seventh cranial nerve and associated to a lymph node was found. The tumor was excised, trying to preserve the integrity of the nerve. The pathological diagnosis of the surgical piece disclosed a benign Schwannoma. The patient had a facial paralysis in the postoperative period.

Palabras clave : Schwannoma; facial nerve; parotid gland.
