Congenital Mucocele of The Lower Lip: Case Report and Literature Review

Mucocele

Oral mucoceles (OMs) are known as asymptomatic benign soft tissue lesions mostly seen in the oral cavity.

Their clinical characteristics include painless, soft, smooth, spherical, translucent, fluctuant single or multiple nodules with minimal irritation.

Although they may appear at any age, most OMs are widely seen in the second and third decade of life. Mucoceles have been classified as either extravasation type or retention type.

Retention type is an actual cyst accumulated with mucin and lined by ductal epithelium.
