Abstract
|
|
|
|
Cellular schwannoma is a benign nerve sheath tumor which presents as a slowly growing tumor in the paravertebral region of the mediastinum and retroperitoneum in middle-aged adults. However it is extremely rare in the oral region. To our knowledge, this is the first report of oral cellular schwannoma in Korean dermatologic literature. Histopathologically, the tumor is characterized by the presence of compact spindle cells arranged into fascicles, variable nuclear hyperchromasia and pleomorphism, lack of Verocay bodies and typical predominance of Antoni A areas. We report a case of cellular schwannoma arising on the lip, which is a very rare location.
