A Case of Left Parotid Duct Cyst

Introduction: Obstruction from any cause can cause dilatation of the parotid duct, which is commonly referred to as parotid duct dilatation. In some cases, the cause of the stenosis is obvious, such as inflammation, salivary stones, tumors, or trauma, while in others, the so-called cases of idiopathic parotid duct dilatation, the cause remains unknown. Herein, we report a case of a salivary gland duct cyst with cystic dilatation of the left parotid duct.
