GIANT EPIDERMOID CYST OF TEMPORAL BONE: A CASE REPORT AND REVIEW OF THE LITERATURE
Abstract
Epidermoid cyst is a thin walled cyst lined by stratified squamous epithelium containing pearly white, soft cheesy material composed of fatty acid and keratin. Intracranial epidermoid cyst is usually located in the cerebellopontine angle, parasellar regions however, temporal bone epidermoid cyst is very rare. We present a case of giant epidermoid cyst in a 42-year-old male of the right periauricular region, temporal region and infratemporal fossa with lytic destruction of right middle ear and inner ear structures, mastoid and squamous part of temporal bone with intracranial but extradural extension which was completely excised. Histological examination confirmed the diagnosis of epidermoid cyst.
