Cystic Myoepithelioma of Parapharyngeal Space

Myoepitheliomas are rare tumours of salivary glands arising from myoepithelial cells, which are normal constituent of the salivary acini and ducts and are found between the epithelial cells and the basement membrane. The most common site of origin of Myoepitheliomas are the salivary glands and rarely other sites in the head and neck have been described in literature. Myoepithelioma arising from parapharyngeal space provide both a diagnostic and therapeutic challenge. We present such a case and discuss its diagnostic and therapeutic aspects.
