ABSTRACT

Objective: To describe the clinical presentation of the facial nerve schwannomas according to the anatomical site of origin. Method: A retrospective study in which the clinical presentation, diagnostic protocol and treatment of facial nerve tumors in adults was evaluated. Results: We found 6 cases, 4 cases of tympanic-mastoid location at the spectrum of its possible clinical presentation: from symptomatic cases with facial paralysis, to an asymptomatic case in the tympanic portion found as intraoperative finding; and also found two cases located at the parotid gland, one with complete facial paralysis and one without facial palsy. Conclusions: For the diagnosis of intratemporal and parotid schwannomas of the facial nerve, a high clinical suspicion is required given its heterogeneous presentation; its clinical course depends on the segment of origin and expansion: more frequently asymptomatic at the tympanic horizontal portion and symptomatic at the mastoid vertical portion. These tumors must be assessed with imaging studies, incisional biopsy is not recommended. The treatment is surgical resection in symptomatic patients with facial paralysis greater than grade III of House-Brackmann, with immediate reconstruction of the nerve.


Objetivo: Describir la presentación clínica de los schwannomas del nervio facial de acuerdo con el sitio anatómico de origen. Método: Se realizó un estudio retrospectivo en el que se evaluó la presentación clínica, el protocolo diagnóstico y el tratamiento de tumores del nervio facial en adultos. Resultados: Se encontraron seis casos, cuatro de ellos de localización tímpano-mastoidea en los extremos de su posible presentación clínica: desde casos sintomáticos con parálisis facial, hasta un caso asintomático de la porción timpánica encontrado como hallazgo transoperatorio; y se encontraron dos casos de localización parotídea, uno con parálisis facial completa y otro sin parálisis facial. Conclusiones: Para el diagnóstico de tumores intratemporales y parotídeos del nervio facial se requiere una elevada sospecha clínica dado lo heterogéneo de su presentación; su curso clínico depende del segmento de origen y de su extensión: más frecuentemente son asintomáticos los de la porción timpánica y son sintomáticos los de la porción mastoidea. Estos tumores deben evaluarse con estudios de imagen; no se recomienda realizar biopsia incisional. El tratamiento es la resección quirúrgica en los casos sintomáticos con parálisis facial de grado IV o mayor de House-Brackmann, con reconstrucción inmediata del nervio.

ABSTRACT

BACKGROUND: Myopericytoma is a perivascular tumor of the skin and subcutaneous tissue of the extremities, it is a rare finding in the head and neck, and even rarer is its deep location. METHODS: A 38-year-old woman presented with a slowly growing mass at the right carotid triangle. Contrast-enhanced CT scan revealed a moderately enhancing mass. At surgery, the tumor was firmly attached to the common carotid artery, making it necessary to excise a small portion of the vessel wall. RESULTS: The histopathologic report was myopericytoma. The postoperative course was uneventful, without tumor recurrence. CONCLUSION: The very few deep located myopericytomas at the head and neck region show a predilection to appear near the great neck vessels with a possibility to require vascular repair, or at the parotid space where they can be multicentric. © 2016 Wiley Periodicals, Inc.

ABSTRACT

Introducción y objetivos: Hay pocos trabajos enfocados a neoplasias de glándulas submandibulares porque son poco comunes y se les agrupa con otras glándulas salivales. En los estudios clásicos se reporta que los tumores malignos en esta localización representan alrededor del 50%. Objetivos: Reportar la proporción de malignidad en pacientes con neoplasia de glándulas submandibulares y tipos histológicos más comunes que se trataron en nuestro hospital del año 2000 al 2010, así como la proporción por sexo y edad de presentación. Métodos: Se realizó una revisión retrospectiva de la base de datos de nuestro servicio de los pacientes que fueron atendidos en 10 años por neoplasia de glándula submandibular. Resultados: Se atendieron 22 pacientes con neoplasias de glándula submandibular, 19 (86%) de tipo benigno y tres malignos (adenocarcinoma, carcinoma epidermoide bien diferenciado y linfoma folicular), edad promedio en patología benigna: 40 años y 55 años en malignos. Hubo predominio del sexo femenino (76%), sin embargo dos de tres casos de neoplasia maligna se presentaron en el sexo masculino. Conclusiones: La mayoría de las neoplasias de glándula submandibular son benignas. El tumor benigno más frecuente es el adenoma pleomorfo. Las mujeres son afectadas con mayor frecuencia. Los tumores benignos se presentan en pacientes más jóvenes que los malignos (AU)


Introduction and objectives: There are few reports focused on neoplasms in the submandibular gland because they are uncommon and are frequently grouped with the other salivary glands tumours. In the classical studies, the proportion of malignancy reported in these cases is around 50%. Objectives: Determining the proportion of malignancy, the most frequent histological types, the gender distribution and average age at diagnosis in patients with submandibular gland neoplasms who were treated in our hospital from 2000 year to 2010. Methods: A retrospective review of our department database of the patients who underwent surgery for submandibular gland neoplasm in a ten-year period was performed. Results: Twenty-two patient records were included, in which 19 (86%) patients presented benign disease and 3 were of a malignant type (adenocarcinoma, well-differentiated epidermoid carcinoma, follicular lymphoma). Two of the 3 cases of malignant neoplasms were in men. Conclusions: A greater proportion of benign neoplasm was found in submandibular tumours. The most frequent benign tumour is the pleomorphic adenoma. Women are more commonly affected (76%). Benign tumours appear in younger patients than do malignant ones (AU)
