1. Introduction
Schwannomas are a group of tumors of the peripheral nervous system
(PNS).In fact, they are an abnormal and usually benign proliferation of
Schwann cells (cells involved in the formation of the myelin sheath in
the PNS). Hence, any nerve in the PNS that contains a myelin sheath can
be the origin of schwannoma, so this type of neoplasm can occur anywhere
in the body (1). It has been reported that in the head and neck region,
the most common site of schwannoma is the cerebellopontine angle
(vestibular schwannoma) (2). Nevertheless, many articles have reported
the development of schwannoma in the pharynx, oral cavity, parotid,
larynx, and scalp (3). About 4% of head and neck schwannomas arise from
the sinonasal region. Several studies reported schwannomas of the medial
wall of the nasal cavity (septal schwannomas) (4). In this manuscript,
we report a very rare schwannoma originating from the lateral nasal
wall.
