“…Complete surgical excision is the treatment of choice with solitary lesion and the chances of recurrence/ malignant transformation are very rare (8-10%). 9,10 In the present case, an excisional biopsy was done and the patient did not present with any symptoms of nerve injury post operatively as the lesion was small and well defined.…”

Schwannoma or neurilemmoma is an uncommon, benign peripheral nerve tumor derived from Schwann cells. It is usually a slow growing, asymptomatic, well encapsulated tumor that arises in association with a nerve trunk.Here we present a rare case of Ancient Schwannoma in a 20 year old male. The patient presented with a small, slow growing asymptomatic mass on the dorsal surface of the tongue, present since past 1year. Lesion was completely excised. Diagnosis was confirmed by histopathology and immunohistochemistry.

“… 14 Traditional surgical techniques for treatment of lesions at the base of the tongue include transoral excision, suprahyoid pharyngotomy, submandibular approach, and mandibulotomy with lip splitting. 1 2 3 4 5 6 8 9 10 11 12 13 14 The transoral surgical approach is the most common and preferred method for small, well-encapsulated tumors, which do not cause any distortion of the airway. 13 While transoral operations eliminate cosmetic disfigurement from scars, this technique is more likely to cause postoperative bleeding and swelling, especially in cases of larger, deeper lesions.…”

Introduction Schwannomas of the head and neck account for 25–40% of all cases, with presentation at the base of the tongue as the most frequent site for intraoral tumors. Objectives Here, a systematic review was conducted to include 15 cases of patients with schwannoma of the base of the tongue. Data Synthesis Most patients presented with a single, painless, well-encapsulated nodule at the base of the tongue. These nodules were slow-growing, with an average of 13.3 months from onset to presentation. Most cases were accompanied by airway obstruction, indicated by symptoms of dysphagia, dysarthria, snoring, and sleep apnea. Overall, the histological studies were consistent with a benign schwannoma with a palisading Antoni A and Antoni B pattern without malignant changes in cell morphology. These tumors were treated via complete surgical excision, and all cases achieved full remission by final follow-up. Conclusion Surgical removal is the primary mode of treatment with excellent postoperative prognosis and rare instances of recurrence. Given the rarity of this tumor, this review of available case studies serves to comprehensively describe clinical presentation and surgical treatment approaches to tongue base schwannoma.

ÖzetSchwannomalar diğer adıyla nörilemmomalar; periferik, kranial ya da otonomik sinir kılıfındaki Schwann hücrelerinden kaynaklanan, yavaş büyüyen, solid ve kapsüllü benign tümörlerdir. Genellikle 20-50 yaşları arasında ve kadınlarda erkeklerden daha sık görülür; K/E:1,5-2/1. Schwannomalar, çoğunlukla baş ve boyun bölgesinden köken alır (%25-48) ve bunların da sadece %1'i ağız içi kaynaklıdır. Yirmi bir yaşında erkek hasta, yaklaşık 6 ay önce çıkan ve son 1 ay içerisinde büyümeye başlayan dil üzerinde kitle, yutma sırasında takılma ve hafif ağrı şikâyeti ile kliniğimize başvurdu. Hastanın oral muayenesinde dil posterior orta hatta yerleşmiş, yüzeyi düzgün, pembe renkli, ağız içine doğru protrüze olmuş, yaklaşık 1,3x1,3x1,4 cm boyutlarında kitle izlendi. Yapılan diğer baş boyun ve sistem muayenelerinde patoloji tespit edilmedi. Rutin kan tetkikleri normal değerlerindeydi. Hastanın dilindeki lezyon genel anestezi altında, transoral yaklaşımla güvenli cerrahi sınır bırakılarak eksize edildi. Histopatolojik incelemede dalgalı nükleuslu hipersellüler (Antoni A), hiposellüler (Antoni B) alanları izlendi. İmmünohistokimyasal çalışmada S100 protein, vimentin ve glial fibriler asit protein pozitif olarak bulundu ve schwannoma tanısı konuldu. Postoperatif dönemde sorun yaşamayan hasta 1 gün sonra taburcu edildi ve 1 yıllık takibinde nüks izlenmedi. Bu çalışmada nadir görülen dil yerleşimli bir schwannoma olgusu sunulmuş olup, konu literatür verileri ile tartışılmıştır. Anahtar kelimeler: Dil tümörleri; nörilemmoma; schwannoma Abstract Schwannomas, also known as the neurolemmomas, are caused by the Schwann cells in the peripheral, cranial or autonomic nerve sheath. These are benign, solid and encapsulated tumors. They grow slowly. Generally they are seen between the ages of 20-50 years old and they are more common in females than males, F / M :1,5-2 / 1. Schwannomas usually arise from the head and neck region (25-48%) and only 1% of them are originated from the inside of the mouth. Twenty one years old male patient was admitted to our clinic with the complaint of difficulty in swallowing and a mass on his tongue for 6 months. In his oral examination, we observed about 1.3 x1,3x1,4 cm mass. Its surface was smooth, pink-colored and was located in the posterior midline of the tongue. It was protruding into the right part of the mouth. In the rest of head and neck examination, no pathology was detected. Routine blood tests were normal. The lesion was excised by transoral approach leaving a safe margin under general anesthesia. In histopathological examination, wavy nuclei hypercellular (Antoni A) and hypocellular (Antoni B) areas were observed. In immunohistochemical study, S100 protein, vimentin and glial fibrillary acid protein was found to be positive and it was diagnosed as schwannoma. In the postoperative period there was not any problem with the patient and therefore he was discharged from hospital one day after the operation. There was no recurrence in the first year follow-up. In this study, we presented a rare case o...
