Schwannoma is a benign tumour of schwann cells and is seldom to be seen in the auricle. In the literature, very few
cases of schwannomas originating in the pinna were reported. In this article, we described a 35-year-old female
patient who presented with right painless auricular mass which was treated by excision under general anesthesia.
The clinical and histopathologic features, the differential diagnosis, and the treatment of auricular schwannoma are
discussed.
Key words: auricle, schwannoma, Iraq.
Introduction: Schwannomas are slowly growing benign tumour of neuro-ectodermal origin. Schwannomas are well
known to arise from schwann cell of the branches of peripheral, cranial or autonomic nerves. They are usually
presented as a painless solitary swelling. They are affecting the head and neck in a 25-45%, where the vestibular
schwannoma is the commonest. The presentation of head and neck schwannomas depends on their location. Auricle
is a rare site of affection by schwannoma (1). The first case of external ear schwannoma was reported in 1977 (2).
When we were reviewing the literatures, only five cases of auricular schwannomas were reported in the world (1-5).
In the present article we describe a further case of auricular schwannoma.
Verocay in 1908 was the first who describe the solitary schwannoma and gave it the name of neurinoma; the name
schwannoma was assigned by Batsakis in 1974. Schwannoma is also known by other terms, such as neurinoma,
neurilemmoma, mioschwannoma, schwannoglioma, etc (6). The first case of auricular schwannoma was reported by
Fodor et al in 1977. Following this case only 4 cases were reported in the world (1-5).
