Abstract
This paper presents a rare case of nasal ala schwannoma. A 48-year-old man had an 8-year history of a right nasal ala tumor. An MRI revealed that the tumor in the right nasal cavity had invaded and eroded the bone. The tumor was removed without difficulty and pathologically diagnosed as a schwannoma. Schwannoma arise from Schwann cells of the myelin sheaths of peripheral nerves. They may be found in any portion of the body. Schwannomas often occur in head and/or neck lesions. They have also been found in the internal acoustic meatus, the pharynx, the tongue, the soft palate, the larynx and the trachea. While the origin of the tumor could not be clarified, the tumor was thought to have originated from either a branch of the anterior ethmoidal or the infraorbital nerve.
