“…Pleomorphic adenomas, which frequently present in the submandibular gland, have similar MRI image with Hypoglossal nerve schwannomas 14 . This suggested that the MRI ndings of hypoglossal nerve schwannomas were not speci c 15 . The patient was diagnosed preoperatively as a submandibular gland tumor base on the symptom and MRI ndings.…”

Background: Hypoglossal nerve schwannoma in the submandibular space is rare. This case report presents the treatment of a young patient affected by an unusual hypoglossal nerve schwannoma at the right side of the submandibular region. Case representation: A 31-year-old female presented to our department with complaints of a right-sided submandibular region mass. None calculi was observed by CBCT. An MRI of the neck demonstrating a 18×12mm mass located at the submandibular region. Based on clinical presentation and imaging, a diagnosis of a submandibular gland tumor was conferred and the patient scheduled for excision. Intraoperatively, the mass was noted to arise from the hypoglossal nerve, remaining independent of the submandibular gland. On histopathologic analysis, the mass was determined to be consistent with hypoglossal schwannoma. Conclusion: Though rare, the hypoglossal schwannoma should remain a consideration in the evaluation of a submandibular space mass. During operation, it might be better to explore the mass before managing the submandibular gland.

“…Patients usually present with an insidious-onset gradually progressive swelling which may or may not be accompanied by paresthesia [ 17 ]. The most common presenting symptoms of Hyn-derived schwannoma included tongue deviation [ 18 ], headaches [ 19 ], vertigo and nausea [ 11 ]. Hypoglossal nerve palsy was the most frequent presenting sign, occurring in 80% of the cases [ 20 ].…”

Background Schwannomas or neurilemmomas are well-encapsulated, benign, solitary, and slow-growing tumors that originate from Schwann cells of the nerve sheath. Extracranial schwannoma is reported to have a relatively high incidence in the tongue while an extremely low incidence in the floor of mouth. In the current study, we presented the first case series of hypoglossal nerve-derived schwannoma in the floor of mouth in Asia. Methods A retrospective study of 9 surgical cases of hypoglossal nerve-derived schwannoma in the floor of mouth was performed. The patient and tumor characteristics were evaluated by physical, radiological and pathological examination. Details of operation and complications were also recorded. Results Hypoglossal nerve-derived schwannoma in the floor of mouth showed a well-defined boundary with a firm texture, smooth surface and good mobility on palpation. The median maximum diameter of the tumors was 4.3 cm (range 2.8–7.0 cm). The median operative time and bleeding volumes were 89.4 min (range 47–180 min) and 99.2 mL (range 15–200 mL), respectively. All cases received complete surgical excision. Conclusion In this study, we presented the diagnosis and management of hypoglossal nerve-derived schwannoma in the floor of mouth for the first time in Asia. The study provided us with a recommendation for consideration of the diagnosis of hypoglossal schwannoma when a patient presents with a mass in the floor of mouth.

“…Neurogenic tumours arise from the neural crest which differentiates into the Schwann cells and sympathicoblasts. 5 The Schwann cells give rise to neurofibroma and neurilemmoma (Schwannoma). 6 Schwannoma is a slow growing solitary and encapsulated tumour attached to a nerve.…”

Introduction Mesenchymal tumours of submandibular gland are extremely rare. Schwannoma of the salivary glands is a particularly rare form of an extracranial neurogenic tumour. Case Report Here, we present an unusual case of schwannoma of submandibular gland in a 16 year old girl, who underwent total excision of mass with submandibular gland excision with no cranial nerve deficits. The details of the histopathologic features are present . Discussion Schwannoma of the salivary gland is a particularly rare form of an extracranial neurogenic tumour. Our case indicates good prognosis in a case of submandibular gland schwannoma after surgical excision.
