“…1 Schwann cells form a thin barrier around each extracranial nerve fiber of motor and sensory nerves and wrap larger fibers with myelin sheath to enhance nerve conductance. 9,10 The possible etiologies of the tongue schwannoma are spontaneous growth, external injury, chronic irritation, or exposure to radiation; but the certain cause of the tongue schwannoma is unknown. 7,11 Loss of function of the merlin protein (coded by gene NF2) appears to be the cause of the appearance of schwannomas.…”

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>

“…The most common site involved is the tongue followed by the palate, floor of mouth, oral mucosa, and mandible. [5] Schwannomas are usually asymptomatic lesions which are slow growing, smooth surfaced, solitary, and of variable size. They usually present as a painless mass, although pain and paresthesia can occur.…”

Ancient Schwannoma is a rare Schwannoma variant which is a painless, slow-growing benign neoplasm of Schwann cell origin. It is relatively a rare tumor in the head and neck region. We report a case of ancient Schwannoma of the tongue in a 38-year-old female patient, who presented with a slowly progressing painless mass over the tongue. Investigatory impression of ultrasonography and fine-needle aspiration cytology of this lesion was suggestive to be a benign tumor of muscle/nerve origin. An excisional biopsy of the mass with primary closure was done. A final diagnosis of ancient Schwannoma was given based on histopathological examination.

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.
