A cyst in the accessory parotid gland (APG) is extremely rare, with only three cases havingbeen reported recently in English literature. They were all treated with sclerotherapy, where acyst may appear as a painless superficial mass in the mid-cheek area. In sclerotherapy, themost commonly used materials are ethanol and OK-432, which report good therapeutic resultsfor the treatment of benign cervical cystic mass. An 85-year-old man came to our clinic withsuperficial, well-margined ovoid mass on the left cheek. The mass was diagnosed as a benigncyst in APG through imaging studies and core needle biopsy. We performed the ultrasoundguidedpercutaneous ethanol injection and the cyst disappeared, leaving only the fused cysticwall. We report this very rare and interesting case with a literature review.
