[Parotid major duct cyst: a case report].

Parotid gland cyst can be congenital or acquired, which is rarely seen in clinic. Cysts in the main duct of the parotid gland are especially rare. We reported a 37-year-old man who presented with a painless mass on the right cheek. Superficial parotidectomy was performed and histopathologic examination of the specimen revealed a main parotid duct cyst. The clinical features, diagnosis, and treatment of the case were discussed and the relevant literatures were reviewed.
