Oral mucocele is the most common benign lesion of the salivary glands generally conceded to be of traumatic origin.
It is characterized by the pooling of mucus in a cavity due to the rupture of salivary ducts or acini.
It can occur in the lower lip, palate, cheeks, tongue and the floor of the mouth.
[1] Appendix mucocele may come as a consequence of obstructive or inflammatory processes, cystadenomas or cystadenocarcinomas.
[citation needed] On a CT scan, a mucocele is fairly homogenous, with an attenuation of about 10-18 Hounsfield units.
