“…20,21 When the CT scans of schwannomas show inhomogeneous areas, a malignant change in the neurogenic tumour may be suspected. 16 In this patient, contrast-enhanced computed tomography (CT) of oropharynx demonstrated a wellcircumscribed soft tissue density mass, oval shape, connected with the left portion base of tongue, homogenous, and strong enhancement mass.…”

Schwannomas are benign tumours arising from the Schwann cells. Around 25-45% schwannomas have been reported occured in head and neck region, but only 1% located intraoral. We report a case of 22 year old woman who presented with foreign body sensation in throat, dysphagia, change of voice, and snoring. There was a slowly growing, solitary, encapsulated, painless, mass on the tongue base. Microscopically, it had the typical features of schwannoma, the diagnosis being supported by a strong positivity for S-100 protein. Ki67 staining showed low proliferative index (<5%) indicated benign schwannoma. CT-scan of oropharynx demonstrated a well-circumscribed soft tissue density mass, oval shape, connected with the left portion base of tongue, homogenous, and strong enhancement mass. The entire mass was removed in general anesthesia with conservative surgical excision via trans-oral route, histopathologic reported consistent as schwannoma. The patient remained disease-free, without any residual problems. Although the rarity of schwannoma on the tongue base, this case highlights the importance of including it in the differential diagnosis of mass from the tongue base. To the best of our knowledge, our case is only the twentieth of schwannoma at the base of tongue that reported in the literature. <p> </p>

“…at the base of tongue to the best of our knowledge. 2,3,5,7,11,14,16 Schwannomas initially appear as slowly growing, generally asymptomatic tumours. Neurogenic deficits do not always correlate with the nerve from which the neoplasm arises, and many patients are asymptomatic.…”

“…Ils peuvent survenir à tout âge, mais plus particulièrement entre 20 et 30 ans (67 % des cas) et il n'existe pas de prédominance de sexe ou de race [1] . 25% des schwannomes se développent dans la région cervico-faciale ; seulement 1 % d'entre eux intéressent la cavité buccale [2][3][4][5] ; ils représentent 1 à 9 % de l'ensemble des tumeurs stomatologiques [2] . D'après la littérature, les schwannomes à localisation buccale intéressent la langue dans 50 % des cas, surtout sa partie mobile, principalement les bords latéraux, alors que l'atteinte de la pointe est très rare.…”

“…L'échographie enregistre un signal homogène, hypoéchogène avec renforcement postérieur. Le scanner montre une masse hétérogène ou homogène, isodense par rapport aux parties molles, avec prise de contraste hétérogène [4,6] . L'IRM montre une lésion isointense aux muscles en T1 et hyperintense en T2, avec prise de contraste après injection de gadolinium [11] .…”

“…Le traitement est chirurgical, il consiste en une exérèse complète de la tumeur sans marge de sécurité, si elle est bien encapsulée. L'examen histopathologique de la pièce montre une tumeur entourée d'une capsule fibreuse, constituée de deux populations cellulaires, les cellules Antoni A (majoritaires) et les cellules Antoni B [4,7] . Les cellules A, fusiformes, enchâssées dans un tissu conjonctif riche en collagène, sont orientées parallèlement, groupées en faisceaux compacts autour d'une zone centrale acellulaire.…”

RÉSUMÉLes schwannomes ou neurilemmomes sont des tumeurs bénignes encapsulées, le plus souvent solitaires, issues des cellules de Schwann des gaines nerveuses. Dans la région cervico-faciale, 1 % des schwannomes sont retrouvés dans la cavité buccale et surtout sur la langue. Les auteurs rapportent le cas d'un schwannome localisé sur le bord latéral gauche de la langue. Une exérèse chirurgicale complète a été réalisée, et l'examen histopathologique de la pièce opératoire était en faveur d'un schwannome. Les suites ont été simples, et après 4 ans de recul, le patient ne présente pas de récidive. Le diagnostic positif repose sur l'examen histopathologique. Le

The aim of this study was to describe clinicopathologic and radiographic features of two cases of schwannoma involving the oral tongue and to review the literature of this unusual clinical entity. Case reports with review of the pathologic, radiologic and clinical data for two patients with schwannoma of the tongue are reported. Review of the literature of case reports of schwannomas (neurilemmomas) of the tongue from 1955 to 2006 with analysis of the patient's age, gender, presenting symptom(s), tumor size, and surgical approach was undertaken. The two patients in our series presented with painless swelling of the tongue. Transoral excision was performed and pathologic examination conWrmed the diagnosis of schwannoma in both the cases. A total of 126 cases of schwannoma of the tongue have been reported in the English literature over the past 51 years. Schwannomas of the tongue typically present in the third decade of life (33%), display no gender predilection (52.8% female; 47.2% male) and often present as a painless mass (69.6%). Schwannomas are likely to elicit distressing symptoms when they occur in the posterior one-third of the tongue (63.2 vs. 13.5%) or approach 3 cm in greatest dimension (33.0 vs. 18.2 mm). The vast majority of cases have been treated with transoral excision (94.8%). Recurrence after surgical excision has not been reported. Schwannoma of the tongue is a relatively rare tumor of the head and neck. Transoral resection allows for removal of this tumor in a manner that precludes recurrence, avoids causing morbidity of tongue function, and remains the standard approach for the treatment of the vast majority of these tumors.
