Abstract
We report a case of primary extracranial meningioma arising from the hypoglossal nerve in a 54-year-old man who presented with a 9-month history of hoarseness and progressive dysphagia. He had also noticed that his tongue was deviated to the left and, as a result, he was having difficulty pronouncing words. Examination revealed fasciculation and muscle wasting on the left side of the tongue. Other cranial nerve functions were normal. Contrast-enhanced computed tomography detected a heterogeneous mass that had arisen above the bifurcation of the left common carotid artery and had extended to near the skull base. Transcervical excision of the tumor was performed, and histopathology identified it as a meningioma of the hypoglossal nerve. The patient recovered uneventfully, and he was without recurrence at more than 2 years of follow-up. A primary extracranial meningioma is extremely rare, and its presentation may be subtle. A thorough investigation is necessary to avoid fatal compressive symptoms.

Abstract
Patients with chronic obstructive pulmonary disease (COPD) may be at increased risk of aspiration secondary to impaired swallow function. One possible cause of this impairment is a reduction in laryngopharyngeal sensitivity. The relationship between COPD and laryngopharyngeal sensitivity has not been previously determined. We conducted a study to investigate the effect of COPD on laryngopharyngeal sensitivity by using laryngopharyngeal sensory discrimination testing (LPSDT). Our study population was made up of 20 adults (mean age: 71.7 yr) with clinically proven COPD and 11 healthy, age-matched controls. All 31 subjects underwent LPSDT with the use of an air-pulse stimulator via a nasendoscope. The threshold of laryngopharyngeal sensation was evaluated by measuring the amount of air pressure required to elicit the laryngeal adductor reflex (LAR). We found that the patients with COPD had a significantly higher LAR threshold than did the controls (p< 0.001). We conclude that patients with COPD have significantly less mechanosensitivity in the laryngopharynx. This sensory change may place patients with COPD at increased risk for aspiration.

Zenker diverticula rarely extend deep into the chest and induce severe dysphagia and aspiration pneumonia. In fact, only rare cases have been reported in the literature that exhibit such significant extension into the mediastinum.

Abstract
Myoepitheliomas are rare and generally benign neoplasms that account for fewer than 1% of all salivary gland tumors. A myoepithelioma neoplasm is almost entirely composed of myoepithelial cells and is most frequently located in the parotid gland and in the minor salivary glands of the hard palate. We report an extremely rare case of myoepithelioma of the vallecular region in a 65-year-old woman and describe this tumor's clinical peculiarity, diagnostic and therapeutic considerations, and prognosis.

Abstract
Dendritic cell sarcoma, not otherwise specified (NOS), is an entity that is poorly defined because of its rarity and poorly understood pathogenesis. It is characterized by positive immunohistochemical staining for S-100 and CD1a, along with an absence of cytoplasmic Birbeck granules on electron microscopy. We report the case of a surgically inaccessible nasopharyngeal dendritic cell sarcoma, NOS, in a 34-year-old man. Treatment with chemotherapy along with adjuvant radiation therapy was successful in decreasing the size of the nasopharyngeal mass, and the patient remained free of any evidence of recurrence nearly 5 years after treatment.
