Ancient schwannoma of the tongue: a case report

A 45-year-old male patient had left sided submucosal swelling extending backwards from the tip of the tongue disturbing articulation and swallowing. Submucosally located lesion was 3 x 2 x 1.5 cm in size and totally excised under local anesthesia. In this article, we present a case of ancient schwannoma of tongue. Although a very rare entity, ancient schwannoma should be considered in differential diagnosis of tongue lesions.     

Base of the tongue metastatic cancer from hepatocellular carcinoma: a case report

Although hepatocellular carcinoma (HCC) is a common malignancy in Taiwan, metastasis to the head and neck area is extremely rare. In this report, we document a case of HCC metastasis to the base of the tongue. The patient involved had been treated for HCC with chemoembolization and radiotherapy 3 years prior to being diagnosed with tongue base metastasis. Symptoms of the metastasis included frequent oozing from the tongue base tumor. The patient died 3 months after a palliative resection of the tongue. To our knowledge, this is the first clinical presentation of HCC metastasis to the tongue base documented in the English language. We also believe that this particular case is important because we predict that the advancement in HCC treatment modalities will allow enough survival time in patients to cause occult extrahepatic metastatic lesion to develop into a field of clinical significance.     

Sinonasal malignant schwannoma: a case report

The malignant schwannoma is rarely found in the nose or sinuses. Two forms are recognized: Isolated or primitive (de novo) and those occurring as part of neurofibromatosis (Von Recklinghausen). OBJECTIVE: To study the clinico-anatomical characteristics, treatment and results together with a review of the literature. MATERIAL AND METHOD: We report the case of a 58 year old patient with a right maxillo-nasal tumour presenting as nasal obstruction and epistaxis. An enlarged paralatero-nasal approach allowed the removal of the malignant schwannoma. Post operative radiotherapy was also undertaken. RESULTS: The patient is fee of disease after ten months of follow up. CONCLUSION: The naso-sinusal malignant schwannoma is a rare tumor which needs precise radiological assessment (TDM - MRI), and treated by surgery followed by postoperative radiotherapy.     

Hairy tongue: a case report

Hairy tongue or black hairy tongue is a benign condition characterized by hypertrophy of the filiform papillae that give the dorsum of the tongue a furry appearance. The color of the elongated papillae varies from yellowish white to brown or black. The etiology is unclear, but the disorder has been associated with numerous predisposing conditions such as heavy smoking, poor oral hygiene, use of topical or systemic antibiotics, systemic corticosteroid therapy, yeast infections, and radiotherapy for head and neck malignancies. A case is presented in which a hairy tongue appeared in a 67-year-old man.     

Inferior turbinate schwannoma: report of a case

Schwannomas of the nasal cavity are extremely rare. We evaluated a 42-year-old woman who presented with a 4-year history of slowly progressive nasal obstruction. The cause of the obstruction was identified as a schwannoma in the left inferior turbinate. The tumor was completely excised, and no sign of recurrence was evident at the 1-year follow-up. To the best of our knowledge, this is only the third case of a schwannoma originating in the inferior nasal turbinate that has been reported in the English-language literature. We review the clinical and pathologic features of this case.

Cervical sympathetic chain schwannoma: a case report

Tumors originating in the parapharyngeal space are rare and are fascinating to the surgeon in view of the anatomical complexity of the area, varied histological type of tumors encountered and the impressive size which some of these tumors attain before becoming clinically evident. We report a rare case of schwannoma arising from the cervical sympathetic chain presenting as a mass in the parapharyngeal space.     

Malignant schwannoma of the mandible: a case report

This article describes a 59-year-old woman with a rare malignant schwannoma invading the left mandible. The clinical, radiological, pathological findings, treatment, and prognosis of our patient are discussed in detail. A 4-year cure was achieved by radical surgery and concurrent chemoradiotherapy (CCRT). In addition, we also review and summarize relevant literature on malignant schwannoma.     

A rare case of schwannoma of the tongue

Author described a rare case of lingual Schwannoma in 20 years old female. After complete surgical excision she has not shown recurrence during 2 years of follow-up. Schwannomas are peripheral nerve tumors of nerve sheath origin. Extracranial schwannoma in the head and neck region comprise 25-45% of all shwannomas, but only 1% are located intraoral and usually present as slow growing mass of long duration, producing few symptoms. The treatment is surgical excision.     

Sarcoidosis of the tongue: a case report

A case of sarcoidosis involving the tongue is described in a 48-year-old Japanese man. A definite diagnosis of sarcoidosis was made for the clinical lesion and pathological examinations. Sarcoidosis is a multisystem granulomatous disease that may affect any organ. Sarcoidosis of the tongue is particularly rare.

Solitary schwannoma of the tympanic membrane: a case report

The external ear canal may be occluded by a rare tumor of the tympanic membrane. We reported herein a case of solid schwannoma arising from the tympanic membrane of a 29-year-old man. It presented as a circumscribed and encapsulated tumor of the external ear canal. The definite diagnosis was based on a careful microscopic examination and pathological findings. A precise excision of the tumor together with part of the tympanic membrane, followed by a myringoplasty was performed. To the best of our knowledge, our case should be the first reported case of this entity in the world literature.     

Malignant schwannoma of the lingual nerve : a case report

Malignant schwannomas of the head and neck are rare tumours that offer various diagnostic and therapeutic challenges encompassing the breadth of modern histupatholagy, radiology and surgery, We describe the only reported case oj a de novo malignant schwannoma affecting the lingual nerve. Presenting a review of the literature and using our case for illustration we discuss some of the pertinent features in the management of patients with this condition.     

Nasal schwannoma: a case report and clinicopathologic analysis.

According to the literature, half of the schwannoma cases occur in the head and neck areas and only less than 4% occur in the sinonasal tract. In this case, a 39-year-old male patient, with a-year-long progressive left side nasal obstruction and purulent rhinorrhea, is presented. The CT reveals a mass filling the left nasal cavity and nasopharyngeal space, with bony erosion of the inferior turbinate and medial maxillary bone. During surgical intervention, the mass is found to originate from the medial side of the left middle turbinate with maxillary sinusitis and inferior turbinate atrophy. The pathological examination reveals a noncapsulated tumor with palisading cellular arrangement and high cellular density. The pathological findings and nervous origin of the tumor are discussed after an extensive review of the literature.     

Cervical schwannoma: a case report and eight years review

Schwannomas are peripheral nerve tumours of nerve sheath origin. We report one case of cervical schwannoma originating from the brachial plexus. A 56-year-old man presented with a slow-growing mass on the right side of his neck that had been noted for more than 10 years. During operation, a well-encapsulated mass was seen beneath the brachial plexus with adhesion to the plexus element. It was reported as a schwannoma. Three days after surgery, the patient had a motor deficit of the right upper arm and neurological examination showed a CV nerve deficit. The neurological function recovered completely after three months. In addition, the other five cases of cervical schwannoma seen in our hospital between March 1990 and June 1998 are also reviewed. All patients had surgery. The pre-operative symptoms, impressions, and post-operative neurological status were shown and discussed. Only two cases were diagnosed as neurogenic tumour pre-operatively. Post-operatively, one patient had transient neurological deficit and another one had permanent deficit.     

Laryngeal schwannoma: a case report and review of the literature

OBJECTIVES: In presenting a case of laryngeal schwannoma, the authors emphasize the difficulties in diagnosing this rare pathology and review treatment options. The recent literature concerning this benign tumour is reviewed. MATERIALS AND METHOD: The authors present a case of laryngeal schwannoma in a 29 year old man, revealed by exertional inspiratory dyspnea. RESULTS: The patient was treated by a conservative surgery with no recurrence after two years follow-up. CONCLUSION: CT scan and magnetic resonance imaging provide essentiel data on the spread of this benign tumour. The possibility of malignant change and recurrence warrant long-term follow-up.     

Oat-cell carcinoma of the tongue: report of a case

We present a case of oat cell carcinoma of tongue in a 76 year old man with a squamous carcinoma of lung.     

Primary tracheal schwannoma: one case report and a literature review

We report a case of primary tracheal schwannoma causing symptoms of airway obstruction in a 51-year-old woman. There was no history of pulmonary disease. The patient had been coughing and suffering from progressive dyspnea for over 1 year. Medical treatment with bronchodilatators had no effect. Computerized tomography and bronchoscopy demonstrated a polypoid mass located inside the tracheas cervical segment, obstructing 50% of the lumen. A biopsy was not attempted because of the tumors vascularity to avoid bleeding. Tracheal resection with primary anastomosis was performed. The diagnosis was confirmed with histological analysis. It revealed a benign neurogenic tumor of Schwanns cell origin. Schwannoma of the trachea is extremely rare. Only 23 cases have been reported previously. Most of them occur in adults (19/23, 82.6%) and are located in the lower trachea. They usually have a long natural history, causing symptoms only after they have attained a large size. The treatment of choice is surgical removal.     

Cellular schwannoma of the paranasal sinuses: initial report of a case

Cellular schwannomas are a benign variant of classic schwannomas. Their histologic appearance closely mimics that of malignant peripheral nerve-sheath tumors, which are high-grade sarcomas. In this article, we describe what to our knowledge is the first reported case of a cellular schwannoma of the paranasal sinuses and only the 33rd reported case of any schwannoma at this site. We also discuss the histology and management of cellular schwannomas and review the pertinent literature.
