ABSTRACT

Mucoceles are painless, rapidly forming swellings that fluctuate in size. They can appear as fluid-filled blisters on
the surface or as deeper nodules within the connective tissue. Extravasation mucoceles occur when trauma to the
salivary gland duct causes mucous to spill into the surrounding soft tissues. This present case shows a 50 years old
female patients was suffering from swelling and ulcerated overlying mucosa at anterior portion of lower lip since 5
years. Patient also have a history of trauma on the same anatomical region 6 years back. Based on the clinical
presentation and past history a provisional diagnosis of mucocele was given. Total excision of the lesion was done
under local anaesthesias. Histopathological findings was suggestive of Mucous Extravasation Phenomenon.
