1/8. Submandibular approach for excision of a large schwannoma in the base of the tongue.

    A 24-year-old Turkish woman is described, who gradually developed progressive swallowing problems over 6 months due to a tumor in the base of the tongue. magnetic resonance imaging showed a large well-circumscribed solid mass. Histopathological examination of an incisional biopsy showed a schwannoma. The tumor was completely removed through a submandibular approach. The postoperative course was uneventful and her complaints disappeared. The submandibular approach used gave an excellent exposure of the base of tongue with a less obvious scar than a lip-splitting incision.

2/8. Benign peripheral nerve sheath tumor of the tongue.

    Peripheral nerve sheath tumors rarely occur in the oral cavity and include neurofibroma, schwannoma, and palisaded encapsulated neuroma. We report a rare case of benign peripheral nerve sheath tumor of the tongue. This tumor was a 0.8 X 0.5 cm sized, firm mass on the left lateral surface of the tongue. Histologically, this mass was composed of well- circumscribed variable sized nodules, which consisted of moderately cellular spindle cells with vague nuclear palisading and a small amount of fibrous tissue. Most of the tumor cells were strongly positive for S-100 protein, but negative for epithelial membrane antigen on immunohistochemistry. No axons were found by immunostaining for neurofilament and Bodian stains. In addition, the surrounding, compressed, fibrous tissue showed rare EMA- positive cells. The present case might be a rare case of neurofibroma arising in the tongue, although immunohistochemical and special stains did not support such a diagnosis.

3/8. Schwannoma of the tongue: one case report.

    The schwannomas are nervous tissue tumours that arise from schwann cells; they are uncommon in peripheral nerves and rare in the tongue. After, a review of the literature, we present a case of schwannoma which arose in the ventral part of the body of the tongue. The tumour presented as a slowly growing mass producing few symptoms. The diagnosis of schwannoma is usually made post-operatively by histological identification although modern imaging techniques can provide useful indications. The treatment is exclusively surgical and usually enucleation of the mass is uncomplicated. There are no reports of malignant transformation.

4/8. Six cases of children with a benign cervical tumor who required tracheostomy.

    Cervical tumors sometimes cause airway obstruction. We have treated six children with benign cervical tumors who required tracheostomy. Two cervical and one glossal lymphangiomata treated with local injection of OK432 after creating a tracheostomy were successfully decannulated after the treatment. One patient with a giant cervical lymphangioma needed an EXIT (ex utero intrapartum treatment) procedure. He underwent tracheostomy at 10 months of age after long-term endotracheal intubation, but he died of sepsis and hypoxic brain damage at 18 months. One patient with a subglottic hemangioma treated with steroids finally achieved closure of the tracheostomy at 2 years of age. A 7-year-old girl with a tracheal schwannoma underwent tracheostomy performed a week after admission, but she already had hypoxic brain damage resulting from problems with intubation. Most patients with a lymphangioma or hemangioma in the cervical region have required early tracheostomy before commencing treatment with OK-432 or steroids. If there is any sign of possible airway compromise, then it is vital to perform an early tracheostomy, even for benign tumors.

5/8. A clinical case report of a Schwannoma on the tip of the tongue.

    OBJECTIVES: Schwannomas (neurilemmomas) are benign solitary tumours which arise from the schwann cells of the neural sheath, most often from the VIII cranial nerve. Extracranially, 25% of all schwannomas are located in the head and neck. Intra-oral development is uncommon and a location in the tongue has been reported in individual cases. METHODOLOGY: We present a young patient with a schwannoma in the distal right side of the tongue. RESULTS: The tumour had grown slowly producing no symptoms. The diagnosis was made on histological examination. Surgical enucleation of the mass was uncomplicated and there was no recurrence. CONCLUSIONS: We report a further case of a schwannoma of the tongue, highlighting the need for this to be considered in the differential diagnosis.

6/8. granular cell tumor of the tongue in a 6-year-old girl--a case report.

    granular cell tumor is a relatively uncommon benign hamartomatous lesion occurring in almost any part of the body. The tongue and the buccal mucosa are common intra oral sites. Granular cell lesions may be found in other diverse sites such as the jaw, skin, gastro intestinal tract and respiratory tract. The histogenesis of the lesion still remains unknown. However, histochemical and ultra structural studies propose the origin of the lesion from schwann cells, striated muscle, mesenchymal cells, histiocytes and epithelial cells. The tumor generally occurs in middle or older aged adults. The lesion is typically seen as an uninflammed asymptomatic mass measuring about two cms in diameter with a yellowish surface coloration. As most of the granular cell tumors are benign, surgical excision of the lesion is the treatment of choice. We describe a case of granular cell tumor of the tongue in a 6 year old girl along with a brief review of literature on granular cell tumors.

7/8. Base of tongue schwannoma: a case report.

    Both malignant and benign lesions may be found on the base of the tongue, including metastasis from other sites. Various surgical approaches to the base of tongue have been described. Here, we report a case of a 26-year-old woman with a schwannoma in the base of tongue removed through a suprahyoid pharyngotomy approach. The biology and pathology of schwannoma in the oral cavity are discussed. The advantage of the suprahyoid pharyngotomy approach for complete excision of a mass in the base of tongue is demonstrated.

8/8. Ancient schwannoma of the oral floor and ventricular portion of the tongue: a case report and review of the literature.

    We report a case of ancient schwannoma, which is a rare benign neoplasm of the oral floor and ventricular portion of the tongue. Only two cases have previously been reported in the English literature. The present tumor, measuring 5.5 x 3.0 x 3.0 cm, was the largest of the three. To differentiate ancient schwannoma from schwannoma with malignant transformation, it is important to confirm the absence of abrupt transition between areas of apparently typical schwannoma and areas composed of atypical large cells with pleomorphic and hyperchromatic nuclei, as well as the absence of mitoses, necrosis, and invasiveness. In the present case, calcification was not detected, nor was hyalinization extensive, although many of the neoplastic schwann cells showed degenerative nuclear atypia.
