Giant schwannoma cases of neck

Schwannomas (neurilemmomas) are solitary neurogenic tumors which are observed rarely and originate from peripheric, cranial or autonomic nerve cells. Twenty-five to 45 percent of extracramal schwannomas occur in the head and neck region. They grow slowly and frequently manifest themselves as asymptomatic masses in the neck. Imaging methods such as ultrasonography (USG), computed tomography (CT), magnetic resonance imaging (MRI) and angiography are helpful in the diagnosis. A 13-year-old boy presented with a slow- growing, painless, 15x10x10 cm mass on the left side of his neck that had been noted 2 years previously. During surgery, a well-encapsulated mass originated from the cervical sympathetic chain was observed. Histopathologic examination was reported as a schwannoma.
