Submandibular gland mucocele associated with a mixed ranula.

Mucoceles of the submandibular gland are extremely rare pathologic occurrences that present an investigative and management dilemma owing to their clinical indistinguishability from plunging ranulas. Of the few that have been documented, these mucous extravasation cysts involved the submandibular gland alone. We describe perhaps the first case of an extensive submandibular gland mucocele occurring in conjunction with a mixed ranula from the ipsilateral sublingual gland, and discuss the various considerations in the management of such lesions.
