“…3 Patients with large tumours (more than 3 cm) or tumours located on the posterior thirds of the tongue are more likely to be symptomatic. 10 The tumor can affect any part of the tongue; the tip of the tongue is the least affected part. 9 Intraoral schwannomas constitute about 1% of intraoral tumors; lingual schwannoma can affect all age groups with the peak incidence being between the third and the sixth decade and there is no gender predisposition.…”

<p class="abstract">Schwannoma is a benign slow-growing tumour that arises from Schwann cells of the peripheral nerve sheath. The head and neck are common locations of this neoplasm. Intraoral schwannoma is uncommon, with the tongue being the most common site. The tumor can remain asymptomatic for a long period of time. The patient may present with symptoms such as a lump, swallowing difficulty, pain or discomfort, voice change, paresthesia, snoring, bleeding or ulceration. The tumor is usually slow-growing, solitary and well-encapsulated and malignant transformation is very rare. Sudden enlargement of the tumor can occur even from trivial trauma. Only approximately 50% of these tumors have a close relationship with a nerve. Transoral resection is the treatment modality of choice. Histopathological examination and immunohistochemistry help in confirmation of the diagnosis. Recurrence of the tumor is very rare. This is a case report of a 26-years-old lady with schwannoma in the ventral surface of the tongue successfully treated by transoral resection with the KTP-532 Laser. </p>

“…Aunque generalmente aparecen aislados, pueden presentarse en mayor número en caso de enfermedades genéticas como la neurofibromatosis tipo I y la tipo II. En este caso, es la pérdida de la función de la proteína merlina (codificada por el gen NF2) el hecho causante del desarrollo de estos schwannomas estimulando las vías mitogénicas y de supervivencia 3 .…”

“…Los schwannomas (también llamados neurinomas o neurilemomas) deben su nombre a que son tumoraciones originadas en las células de Schwann situadas en la vaina que rodea a los nervios periféricos 1,2 . Afectan en su mayoría a nervios sensitivos y pueden afectar a todos los pares craneales excepto al nervio óptico y al olfatorio 3 . Estas tumoraciones se originan cuando las células de Schwann situadas en el perineuro comienzan a proliferar.…”

Introducción: Los schwannomas son neoplasias predominantemente benignas y de crecimiento lento originadas en las células de Schwann de los nervios periféricos. En la cavidad oral su prevalencia es muy baja, siendo la localización más frecuente la lengua. El diagnóstico se basa en la RMN y el estudio histológico. El tratamiento de elección es la exéresis quirúrgica. Caso clínico: Presentamos el caso de una mujer de 73 años que acude a urgencias por una tumoración en cara ventral de punta lingual de tiempo incierto de evolución. Después de estudio histológico y radiológico de la misma se confirma el diagnóstico de schwannoma lingual por lo que es intervenida realizándose exéresis de la lesión que confirma finalmente el diagnóstico.Discusión: El schwannoma lingual es una neoplasia benigna poco frecuente cuyo pronóstico es excelente y con bajas tasas de recurrencia tras su exéresis quirúrgica.

“…Approximately 25% of all schwannomas occur in the head and neck. Intraoral schwannoma accounts for 1% of all head and neck schwannomas and commonly seen at the tongue (66% in anterior third of the tongue vs 34% in the posterior two thirds) followed by palate, floor of mouth, buccal mucosa, gingiva, lips and the vestibular mucosa in descending manner [37,38] .…”

Head and neck schwannomas represent a considerable percentage of extracranial schwannomas. However, intraoral locations are very rare. Schwannomas of the tongue base have been sporadically reported. The exceedingly paucity of literature reports in this location made them usually skipped out when evaluating a tongue base mass. In this work, we aimed to review the literature about this tumor and to report a new case. A comprehensive review in English literature of tongue base schwannomas was done with extraction of the related articles and descriptive analysis of the collected data. Also, we presented a new case of 20-year old girl that presented with a slowly enlarging mass of the tongue over 11 years duration. CT and MRI revealed a large well-defined tongue base mass. Biopsy revealed schwannoma. Transoral complete resection with safety margins was done. Forty-three cases have been reported in literature with slight female predominance. Transoral approach was the commonest approach (76.7%) with the maximal diameter of schwannoma removed transoral was 7.9 cm. In conclusion; despite their rarity, tongue base schwannomas should be included when ever a benign swelling is suspected. Transoral approach is still the standard approach with the least morbidities and best functional outcomes.
