Resumen: Los neurilemomas son tumores neurogénicos benignos, con origen en la vaina neural. De los neurilemomas extracraneales, aproximadamente un 25 a un 45% ocurren en cabeza y cuello. La edad de afectación predominante es entre la tercera y la cuarta décadas de vida. El neurilemoma es un tumor claramente circunscrito y, generalmente, de pequeño tamaño. Clínicamente aparece como una masa de crecimiento lento y gradual. El examen microscópico es necesario para el diagnóstico. El tratamiento de elección es la escisión quirúrgica completa tumoral y después de ésta es muy rara su recurrencia. El propósito de este artículo es presentar un estudio retrospectivo, de nueve casos, de neurilemomas de cavidad oral y cuello, tratados en nuestro servicio de Cirugía Oral y Maxilofacial, entre 1997 y 2001. Hemos valorado una serie de parámetros epidemiológicos (edad, sexo, localización, tamaño, clínica, estudios previos a la cirugía, tiempo trascurrido entre aparición de síntomas y primera consulta, nervio de origen, patrón histológico predominante (Antoni A, Antoni B), y evolución postquirúrgica. Se ha realizado una revisión de la literatura.Palabras clave: Neurilemoma; Schwannoma; Cavidad oral; Cuello. Abstract: Neurilemomas are benign neurogenic tumours, that derive from the neural sheath. Approximately 25 to 45 per cent of the extracraneal neurilemomas occur in the head and neck region. Neurilemomas usually occur between the third and the fourth decades of life. Neurilemoma is a sharply circumscribed, and usually small tumor. Clinically it manifests as a slow and gradually growing mass; microscopic examination is neccesary for diagnosis. Complete tumoral excision remains the treatment of choice and after this, they rarely recur.The aim of this article is to report a retrospective study, of nine cases, of oral cavity and neck neurilemomas, treated in our service of Oral and Maxillofacial Surgery, between 1997 and 2001. A series of epidemiological parameters (age, sex, location, size, symptoms, preoperative study, time Neurilemomas de cavidad oral y cuelloNeurilemmomas of the oral cavity and the neck

ÖZSchwannom veya nörilemmoma periferik sinirlerin Schwann hücrelerinden kaynaklanan; yavaş büyüyen, soliter ve kapsüllü bir benign tümördür. Dil schwannomları nadirdir. Kırk altı yaşında bir erkek hasta yaklaşık bir yıldır devam eden, dilin sağ yarısında şişlik yakınması ile başvurdu. Dilin sağ kenarında submukozal yerleşimli yaklaşık 1x1 cm'lik kitle tespit edildi. Submukozal kitle lokal anestezi altında total olarak çıkarıldı. Patolojik inceleme schwannom ile uyumlu idi. Dil schwannomları dil kitlelerinin ayırıcı tanısında dikkate alınmalıdır.Anahtar Sözcükler: Nörilemmoma; oral kavite; schwannom; dil. ABSTRACTSchwannoma or neurilemmoma is a slow growing, solitary, and encapsulated benign tumor originating from Schwann cells of the peripheral nerves. Lingual schwannomas are rare. A 46-year-old male patient admitted with a complaint of swelling on the right half of the tongue for one year. An approximately 1x1 cm submucosal mass was detected on the right side of the tongue. The submucosal mass was totally excised under local anesthesia. Pathological examination was consistent with schwannoma. Lingual schwannomas should be considered in the differential diagnosis of tongue masses.

“…Magnetic resonance imaging is superior to other imaging modalities for examining intraoral lesion. A schwannoma is smooth and well-demarcated, and it is isointense compared to muscle on T1-weighted images and it is homogeneously hyperintense on T2-weighted images 20 . Schwannoma is a benign peripheral nerve sheath tumor with the gross presentation with being a gelatinous or cystic long encapsulated or unencapsulated mass with occasional secondary changes such as cystic degeneration, hyalinized vessels and necrosis 21 .…”

(J Korean Assoc Oral Maxillofac Surg 2011;37:530-4) This paper reports two cases of schwannomas arising from the oral cavity. One is an intraoral ancient schwannoma located at the left cheek, which evolved over a period of 13 years. The tumor was a well-demarcated buccal mass, which was located in the left lower first premolar area, with an obliterated the buccal vestibule, leaving the overlying mucosa intact. The second case was a central intraosseous schwannoma located from the left lower 1st molar periapical area to the left 3rd molar periapical area. Pathologically, the first mass was composed of the spindle shaped tumor cells with wavy nuclei beneath the fibroconnective tissue of the gingiva but second case mass was not. Occasional nuclear pleomorphism was observed but mitosis or necrosis was absent. There were Antoni A and B areas along with strong, diffuse staining with the S-100 protein. Ancient schwannomas were diagnosed. Schwannoma is a slow-growing benign tumor, and an ancient schwannoma that shows cellular atypism is a variant of a schwannoma caused by purely degenerative changes. To date, only limited cases of ancient schwannomas in the oral cavity have been reported.
