Resumen
Introducción

La existencia de metástasis parotídeas ha sido reflejada en la literatura, siendo su tratamiento controvertido

Material y métodos

Se realiza un estudio retrospectivo sobre 48 pacientes sometidos a cirugía de parótida entre los años 1997 y 2004, revisándose aspectos clínicos e histológicos

Resultados

De los 48 pacientes intervenidos, en 12 casos se diagnosticó metástasis parotídea de un tumor primario (25%). El estudio histopatológico identificó: tumor primario en la piel en 9 pacientes (8 carcinomas epidermoides y 1 melanoma), 2 linfomas de localización inicial infraclavicular y un carcinoma renal de células claras. Los 12 pacientes fueron sometidos a parotidectomía, acompañada de vaciamiento ganglionar cervical en 10 pacientes (en 6 de ellos se identificaron metástasis ganglionares); 8 pacientes recibieron tratamiento radioterápico postquirúrgico

Conclusión

En nuestro estudio las metástasis parotídeas son relativamente frecuentes en el global de los pacientes intervenidos por tumores de parótida. En la mayoría de las ocasiones el tumor primario se encuentra en zonas cutáneas próximas (melanomas o carcinomas epidermoides), aunque es posible que el tumor primario se encuentre por debajo de las clavículas

Palabras clave:
Metástasis
Glándula parótida
Tumores malignos secundarios
Abstract
Introduction

Metastatic disease in the parotid gland has been observed and reported in the literature, and its treatment is controversial

Material and methods

We review 48 patients with parotid tumors that underwent surgery during 1997-2004. The clinical and histogical features are reviewed

Results

Among these 48, there were 12 cases of metastatic tumors to the parotid (25%). The pathohistological analysis of these tumors revealed that 8 were epidermoid carcinoma (66%), 1 patient was a melanoma (8%), 2 lymphomas below clavicules (16%) and 1 patient with a metastasis of a primary renal cancer. All patients underwent parotidectomy and 10 also cervical neck dissection (6 cases showed cervical metastases). 8 patients received radiotherapy after surgery

Conclusions

In our study parotid metastases are relatively common in patients submitted for parotid surgery. Often the site of origin of the primary tumor is the facial skin, and the primary tumors most commonly are melanomas or squamous-cell carcinomas, but it is possible distant primary tumors below clavicules
