Mucous Retention Cyst – Review of Literature and a Case Report

Mucocele is a mucin filled cavity and is one of the most common salivary gland pathology. It arises either due to severance of a duct or due to an obstruction to the salivary flow. In the former case, the more appropriate term is mucous extravasation phenomenon and the latter is called mucous retention cyst. We present a case of mucous retention cyst in 21-year-old boy who presented to Dental Out Patient Department with a chief complaint of swelling in his lower lip. With this case report we also attempt to review and highlight the differences between the two entities with a common name.
