Two cases of granular cell tumors of the head and neck at different sites.

Granular cell tumor (GCT) is an uncommon, primarily benign lesion. We describe 2 cases of GCT. Patient 1 was a 38-year-old man who presented with a reddish, vegetative lesion that involved the posterior third of the left true vocal fold.

Carotid body tumors and our surgical approaches.

Glomus tumors known as paragangliomas are neoplasms arising from the neural crest. They are named according to the place they originate from. Tumors originating from the carotid body at the carotid bifurcation are called Carotid Body Tumors (CBT).

Laryngeal granular cell tumor; rare location.

Granular cell tumors are benign subcutaneous or submucosal lesions of neurogenic origin. In this case study one patient was diagnosed and treated successfully with complete surgical resection of a laryngeal granular cell tumor that was originated from the left arytenoid region that very rare location. There is no evidence of recurrence 2 years after surgery.

The protective effects of intratympanic dexamethasone and vitamin E on cisplatin-induced ototoxicity are demonstrated in rats.

Cisplatin ototoxicity is a major dose-limiting factor in the treatment of several neoplasms. Dexamethasone and vitamin E are two slow-acting free radical cleaners, and they have been shown to ameliorate nephrotoxicity and endothelial cell damage in animals receiving cisplatin. The purpose of the study was to determine the effectiveness of vitamin E and dexamethasone as an otoprotectant intratympanically.
