Neurilemmoma of maxillary alveolus: A rare case report and review of literature

Abstract

Schwannomas or neurilemmomas are benign, slow growing, usually solitary and encapsulated tumor, originating from Schwann cells of the nerve sheath. Intraoral schwannomas account for 1% of head and neck region and are commonly seen at the base of the tongue. Most of the literature, reports of schwannomas in the tongue region are common. In this article we report a rare occurrence of schwannoma in the maxillary alveolus region and its management. A 45 year old female patient reported to the department of oral and maxillofacial surgery with a complaint of swelling in the left maxillary alveolus in relation to molar teeth that had been present for more than 3 months. Apparently the swelling was small one initially, which gradually increased in size. Such a rare cas e of intraoral schwannoma should be followed up periodically to look for any malignant transformation and recurrences. An important conclusion that has evolved from the reviewed articles, is that the differential diagnosis of painless nodules in head and neck must include schwannomas.

“…Recurrence of the lingual schwannoma has never been reported after complete resection [14]. Although malignant transformation is extremely rare, long-term follow-up is always required [15].…”

Solitary Large Intraoral Neurilemmoma of the Maxillary Vestibule: A Rare Case with Brief Literature Review

“…4 Lesions may be further classified into central or peripheral type. 5 While the precise etiology is unknown, mutation of the NF2 Schwann cell regulator gene is implicated. 4 It is hypothesized that lesions occur due to the proliferation of Schwann cells, leading to compression and displacement of the associated nerve.…”

“…2 Their appearance intraorally is uncommon, accounting for 1% of tumors in the head and the neck region. 5 In the oral cavity, the tongue is the most frequently affected, followed by the roof of the mouth, the floor of the mouth, the buccal mucosa, the gingiva, the lips, and the vestibular mucosa. 4 , 5 While neurilemmoma can occur at any age, but the peak incidence is between the second and third decades of life.…”

Malignant peripheral nerve sheath tumor in the maxilla. Clinical сase

“…В полости рта встречается не более 1 % от общего чи сла ЗОПН головы и шеи, их преимущественной локализацией считается корень языка. Расположение в области альвеолярного отростка верхней челюсти, так же как и внутрикостное расположение образований этой морфологической группы, наблюдается крайне редко [1][2][3].…”

“…Рентгенографическим отличием ЗОПН является четкая склеротическая граница. В качестве диагностических методов для оценки распространенности поражения, а также инфильтрации окружающих структур при обширных поражениях могут применяться ультразвуковое исследование, компьютерная томография с контрастированием и магнитно-резонансная томография [1].…”
