Accessory parotid gland (APG) tumour is a rare pathology located at the mid-cheek or infra-zygomatic region. APG is usually away and separated from the main parotid gland. APG lies on the masseter muscle anteriorly and empties into the Stensen’s duct via multiple accessory ducts. We report a case of mid cheek swelling associated with APG. In the literature, the prevalence of accessory parotid gland tumours is around 1% to 7.7%. High suspicion is needed for the diagnosis of accessory parotid gland tumours because of its rarity.
