Abstract

Schwannomas of the sinonasal tract are very rare benign neoplasm, which can arise from nerve sheath containing Schwann cells. Epidermal cysts are also rarely present in nasal cavity. They are thought to be congenital lesion associated with various craniofacial disorders or arise as a result of implantation of epidermal cells into the deeper dermal element. Several cases of the nasal schwannoma or epidermal cyst have been reported repectively, however nasal schwannoma with epidermal cyst never has been reported yet. We report the first case of nasal schwannoma which is coexists with epidermal cyst at the superior turbinate of the nasal cavity.
