Schwannoma Located in Nasopharyngeal Region

Schwannoma is a tumor which has neuroectoderm origins, is hard, well-circumscribed, encapsulated, and slow growing benign cranial tumor, and may autonomously grow out of the nerve sheath of peripheral nerves. It is mostly seen in the head and neck region. In the paranasal sinus and nose areas, it is seen at a rate of 4%. The diagnosis is mostly made after histopathological examination. In this paper, a Schwannoma case observed in the nasopharyngeal region was presented in a 20-year-old female who had complaints of sleeping with open mouth, snoring, foreign body feeling in throat, and swallowing difficulties. The tumor was extracted via transoral approach. No recurrence was observed during follow-up over the next year. This case presentation is presented for the first time in the literature in English.

Chondroid syringomas are uncommon cutaneous neoplasms of sweat gland origin which are slow-growing, nontender, subcutaneous or intracutaneous in location and often occurring in the head and neck region. Chondroid syringoma should be considered in the differential diagnosis of any subcutaneous nodule over the face. The clinician may miss the diagnosis of this lesion and if it is suspected, tumour should be excised with a margin of normal tissue and regular follow up should be done.

Rare Diagnosis

Schwannomas/ neurilemmomas are benign tumors of nerve sheath arising from Schwann cells that form myelin sheath around peripheral nerves. They are usually solitary, slow growing and encapsulated lesions. Head and neck are the common sites. We report a case of a 38 years old Nepalese female who had presented with a solitary asymptomatic, slow growing nodule on the left side of the chin for the last three years. Dermoscopy of the lesion revealed arborizing vessels with brownish pigmentation overlying a whitish to pinkish background. Complete excision of the lesion was performed. Histopathological evaluation of the lesion revealed schwannoma. Though schwannomas are a rare diagnosis, they should be considered as a differential diagnosis of any unilateral, asymptomatic, slow growing nodule in the head and neck region. Dermoscopy is a useful tool which helps to differentiate schwannoma from other lesions. Histopathology is the gold standard for diagnosis and the treatment of choice is surgical excision.

Chondroid syringoma is a rare, skin appendageal tumor. It is also known as mixed tumor of skin, as it histologically resembles mixed tumor of salivary gland (pleomorphic adenoma). It is most commonly a benign tumor, but a few malignant counterparts have been described in history. It usually presents as a solid, slow-growing, solitary, and painless nodule in the head and neck region. Malignant counterpart is rare and commonly affects trunk and extremities. Early diagnosis and surgery by wide local excision are the most reliable treatments to date. Recurrences are common and hence close follow-up is advised. In this study, we present a case of malignant chondroid syringoma of face with extensive extension into nose and paranasal sinuses, which was recurrent and managed by surgical excision and radiotherapy. To the best of our knowledge, this is the first reported case with extension and bone destruction into nose and sinuses.

Chondroid syringoma (CS) is a rare benign appendageal tumour of the skin, with histological similarities to pleomorphic adenoma of salivary glands. It typically presents as a slow growing nodular mass generally less than 3 cm, arising from the skin, predominantly in the head and neck region. We report a case of a 61-year-old male with a massive nasal mass attained over a period of 2 years. A fine needle aspiration of the lesion was suggestive of CS. It was excised completely under general anaesthesia. The postoperative histopathology was also consistent with CS. The patient was followed up on a regular basis and was rendered disease free till his last follow up at 4 months. Our purpose of reporting this case is to highlight the rarity of the disease entity, as well as the occasion of it acquiring a large size yet, maintaining its benign nature.

Schwannomas are relatively rare benign neoplasms of neurogenic origin from the neural sheath of peripheral nerves occurring more commonly in the head and neck. Mandibular bone is the commonest site of occurrence of these nerve lesions. Radiographically, intraosseous schwannoma of mandible is very difficult to differentiate from other bony pathologies such as neurofibroma, ameloblastoma, fibrous dysplasia, myxoma, central giant cell lesion, or periapical lesion, so it should be included in the differential diagnosis of lower jaw swelling. Schwannoma as a pathologic entity was first reported in 1910 by Verocay. Schwannoma (also known as neurinoma, neurolemmoma, neurilemmoma, perineural fibroblastoma, and peripheral nerve sheath tumour) is a rare, slowgrowing, benign neurogenic neoplasm that originated from Schwann cells. Schwann cells cover myelinated sheath of nerve fibres.1 These intraosseous schwannomas account for not more than 1 % of the central neoplasms. More than one third of all schwannomas are found in the head and neck region. 2 Most of these originate from the lower cranial nerve and sympathetic nervous system. Schwannomas from the upper cranial nerves such as trigeminal nerve and its branches are less common. Other commonly reported sites include the vertebra, clavicle, ribs, sacrum, humerus, ulna radius, etc. This painless slow-growing neoplasm may develop at any age.

Neurilemmomas are slow growing, benign neoplasms of neural crest Schwann cell origin. They arise from any peripheral, spinal or cranial nerve except the olfactory and optic. Presentation is usually asymptomatic but focal neurological signs and symptoms may be associated with nerve compression. With approximately one third of all documented cases presenting in the head and neck region, we report a case of a submandibular neurilemmoma misdiagnosed pre-operatively. The diagnostic difficulties are discussed and the current literature reviewed. Thiscase highlights the importance of inclusion of nerve sheath tumours in differential diagnoses of soft tissue lesions in the head and neck.

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.

Background: Synovial sarcoma is a rare soft-tissue malignant tumor most commonly occurring in the extremities and head and neck region, and rarely occurring in the pericardium. Case presentation: We report a 7-year-old boy was admitted to the hospital with recurrent fever and chest pain over the past four months. A cardiac magnetic resonance imaging (MRI) revealed a tumor beneath the heart in the pericardial, and we surgical resection it completely. The postoperative histopathological examination resulted in a diagnosis of monophasic spindle cell type synovial sarcoma. After two weeks of hospitalization, the patient was discharged. Three months after discharge, the positron emission tomography (PET/CT) scans did not show any signs of recurrence. Conclusion: Pericardial synovial sarcoma is a rare disease that is detected early, and complete resection improves patient survival. We recommend CT be performed in patients with recurrent fever and sizeable pericardial effusion to rule out possible pericardial synovial sarcoma considering the echocardiography limitations.

Schwannoma is a slow growing benign peripheral nerve sheath tumor arising from schwann cells. It is also known as neurilemmoma. Although it is common in the head and neck region, it rarely exceeds 10 cm in size. Usually Schwannomas are not larger than 5 to 6 cm in diameter. Large tumors are uncommon and are found in posterior mediastinum or retroperitoneum. We are presenting an unusual giant cell schwannoma over face (cheek) measuring 12×10 cms in size which caused facial deformity to the patient. The tumor was diagnosed on FNAC where cell block was prepared and IHC was done which showed S-100 positivity. This size schwannoma over cheek site has not been reported in the literature as far our knowledge. Therefore this case is unique for its size over face.
