Extranasopharyngeal angiofibroma originating from the nasal septum: a case report.

Angiofibromas (AFs) originate predominantly in the nasopharynx and posterior nasal cavity. The incidence of these lesions is less than 0.5% among all neoplasms of head and neck.

The role of GSTM1 and GSTT1 polymorphisms in head and neck cancer risk.

Head and neck cancer (HNC) is a serious health problem worldwide and tobacco smoke is a main causative factor for this malignancy. Interindividual genetic differences in enzymes involved in the metabolism of tobacco smoke carcinogens are one of the most important risk factors in the development of HNC. GSTM1 and GSTT1 enzymes participate in detoxifying of tobacco smoke carcinogens and have deletion polymorphisms.

Unusual location of hydatid cyst: soft tissue mass in the neck.

Hydatid disease is a parasitic infestation caused by the larval form of the cestode worm Echinococcus. The most commonly encountered form of the disease is visceral hydatid cyst caused by Echinococcus granulosus or dog tapeworm. We hereby represent an unusual case of hydatid disease located in the neck region in a 22-year-old female patient.

Oral and intralesional steroid therapy in giant cell granuloma.

Giant cell granulomas account for 7% of all benign tumors of the jaw. They are commonly seen as asymptomatic masses. A 4-year-old boy with an exophitic, crusty, hemorrhagic mass on the anterolateral region of the right maxilla was referred to our department.
