ranula
Pronunciation: RAN-yoo-lah
A mucous retention cyst arising from the sublingual gland or its ducts, appearing as a bluish, translucent swelling in the floor of the mouth.
Full Definition
A benign cystic lesion in the floor of the mouth resulting from extravasation or retention of saliva from the sublingual gland. Simple ranulas are confined to the sublingual space, while plunging ranulas extend through the mylohyoid muscle into the neck. The name derives from the Latin 'rana' (frog) due to its resemblance to a frog's underbelly. Treatment options include observation for small lesions, marsupialization for simple ranulas, or excision of the sublingual gland for recurrent cases. Differential diagnosis includes epidermoid cyst, dermoid cyst, and other floor-of-mouth masses.
Usage
Usage note: Distinguish between simple and plunging ranulas in clinical documentation.
