Trachea stenosis is observed either in benign or malignant situations. In cancer malignancy a tumor might obstruct the central airway in three different ways. Again granuloma tissue is usually observed after intubation or stent placement in order to manage a benign malformation of the trachea.

Background: Malignant peripheral nerve sheath tumours (MPNSTs) are highly aggressive neoplasms with a marked propensity for local recurrence and metastatic spread. The management of MPNSTs continues to challenge pathologists and surgeons. As MPNSTs of the paranasal sinuses and the skull base are rare, prognostic factors and treatment modalities have not been consistently identified.

A retrospective analysis of 10 patients was performed to evaluate navigation systems in extranasal frontal skull base surgery. When performing a craniotomy following a bicoronal skin incision, the surgeon has to calculate the extent of the frontal sinus to avoid unnecessary damage to the dura or mucoceles later. Due to surgical morbidity including compression of the frontal lobe, many skull base surgeons have refused to use such an approach.

This cadaver study assessed the value of navigation in cochlear implant surgery. Cochlear implantation was simulated on a cadaver using a Stryker-Leibinger navigation system and a Nucleus 24 Contour implant. A conventional surgical strategy consisting of mastoidectomy, posterior tympanotomy, and cochleostomy was performed.

Burkitt's lymphoma is rare outside of Africa, and head and neck manifestations of this disease are even more uncommon. We report a case of Burkitt's lymphoma localized at the bifurcation of the right common carotid artery in a 64-year-old man. The presenting symptoms were recurrent syncopes that necessitated a pacemaker, followed by a rapid onset of cranial nerve palsies.

We report the case of an extranodal non-Hodgkin's lymphoma mimicking a benign tumor in the left parotid gland of a 71-year-old woman. The clinical presentation of the painless, mobile mass was suggestive of a benign parotid tumor such as an adenoma. The intraglandular tumor appeared sonographically as a well-circumscribed, hypoechoic, homogeneous, lobulated mass with mild distal sound enhancement.
