Schwannoma, otherwise known as neurilemmoma, is a benign tumor that originates from Schwann cells. Ancient Schwannoma is a long-standing Schwannoma with degenerative and xanthomatous changes. The Head and neck region is one of the most common sites for nerve sheath tumors but Involvement of the jaw is a considerably infrequent event. We report a rare case of intraosseous ancient Schwannoma of the mandible in a 24-year-old male patient which was initially misdiagnosed with carcinoma. The clinical features, radiographic findings, and treatment plan are discussed. Furthermore, a thorough literature review demonstrated nine published cases of intra-osseous ancient Schwannoma with their summarized features. Recognition of various histopathologic features of ancient Schwannoma is essential to prevent over-treatment.

ABSTRACT Schwannoma is a benign tumor that originates from perineural Schwann cells of nerve sheath. They are solitary, wellencapsulated, slow-growing adjacent to the parental nerve but extrinsic to the nerve fascicles. Approximately 25 to 45% of all schwannomas are seen in the head and neck region and are found rarely in the oral cavity. Most of the intraoral schwannomas are located in the tongue. Palatal schwannoma is very rare as till date and only 16 cases have been reported; one such rare case we came across is reported here. How to cite this article Hameed PSS, Arora N, Malhotra V.

An osseous choristoma is a benign tumor consisting of regular bone tissue in an irregular localization. Choristomas in the head and neck region are rare. Most frequently, they are found in the region of the tongue or oral mucosa. There are also very few reports on osseous choristomas in the submandibular region. We present the case of a woman with a large, caudal osseous choristoma within the lateral cervical triangle. Literature review is given about all of the reported cases in the region of the neck. The pathogenesis is yet unexplained. Our case supports the theory that the development of an osseous choristoma is a reaction to a former trauma. Cervical osseous choristomas are seldom, but they represent an important differential diagnosis when dealing with a cervical tumor.

Malignant peripheral nerve sheath tumours (MPNSTs) are rare, aggressive softtissue sarcomas associated with poor prognosis, that most commonly affect patients aged20 to 50 years, but have also been reported in children. The tumour is usually found in lowerextremities and only 10% to 20% of all lesions occur in head and neck region thus making ita rare entity. Central involvement, particularly in the jawbones is quite unusual. There is littlereported in literature on these tumors in Africa. Here we report a rare case of intraosseousMPNSTS occurring in the mandible in a 12-years old girl. The biological behavior and diagnosticchallenges of this rare malignancy are discussed.

Pleomorphic adenoma is a benign tumor of the salivary gland with the highest incidence rate among all salivary gland tumors in the general population. Even though it’s common, ectopic presentation of the same is rare. When it happens, it presents in the head and neck region. We discuss in this paper a rare case of ectopic pleomorphic adenoma on the plane of the cheek.

Schwannomas are usually single, encapsulated, and benign tumors of the nerve sheath that arise from the perineural Schwann cells. Schwannomas are mostly seen in the fourth decade. Despite its location in the head and neck region is 25–45%, lip location of schwannoma are very rare. We present a case of a upper lip schwannoma in the pediatric age and review the literature.

ABSTRACTSchwannoma also known commonly as neurilemmoma and schwann cell tumor is a benign nerve sheath tumor. About 1/3rd cases of schwannoma arise from the head and neck region but rarely from the nasal and paranasal sinuses. The recurrence rate in these cases has reported to be very rare. We report a rare case of schwannoma in a 60-year-old woman arising from the maxillary sinus further eroding the orbital floor and nasal bone. We have also described the clinical presentation, radiological, histological findings, and management of the case.

Schwannomas are benign nerve sheath tumors composed of Schwann cells, which normally produce the insulating myelin sheath covering peripheral, cranial and autonomic nerves. Twenty-five to forty-five percent of all schwannomas occur in the head and neck region, but location of such tumors in the larynx is rarely observed. The present report is aimed at describing a clinical case of laryngeal schwannoma, with emphasis on sonographic findings.

Neurinoma or schwannoma is an uncommon benign tumor that arises primarily from the nerve sheath of Schwann cells. About 25% has been reported in head and neck region extracranially, but only 1% in the intraoral origin. Intraorally, the tongue is the most common site followed by the palate, floor of the mouth, lips and buccal mucosa. In review of literature, intraoral schwannoma of the lingual nerve origin has not been reported frequently. So, we present a case of intraoral neurinoma of the lingual nerve.

ABSTRACT Neurilemmoma, also known as schwannoma, is a benign tumor arising from the neural sheath Schwann cells. This tumor has a predilection for the head and neck region but it is rarely found in the oral cavity (1%) where tongue is reported to be the favored site. We report a rare case of neurilemmoma of the hard palate along with a review of literature of this entity.
