Minor salivary glands: Causing major problems

Tumours arising in the parapharyngeal space (PPS) are rare and account for approximately 0.5% of all head and neck neoplasms. ¹² These neoplastic processes represent a wide variety of both benign (80%) and malignant lesions arising from the diverse range of structures within and surrounding the PPS.¹² The PPS is typically conceptualized as a potential neck space in the shape of an inverted cone with its base at the skull base and apex at the greater cornu of the hyoid. Because of this unique structure, lesions must often grow to a considerable size before symptoms become apparent and clinical detection is possible. A rare case of mucoepidermoid tumour of the minor salivary glands arising in the pretyloid parapharyngeal space is described. The complex anatomical and pathological considerations within this region present a substantial challenge to the head and neck surgeon in the evaluation and management of these lesions.
