What Is a Maxillary Mucous Retention Cyst?

Mucus cysts are usually caused by mucus gland duct obstruction and mucus retention. They can occur on the lips, cheeks, tongue mucosa, and the lower lip and ventral surface of the tongue. Mucus cysts are located under the mucosa, about the size of a soybean, and appear as translucent painless vesicles. After the rupture, mucus can flow out and the mass subsides, but it can soon return. After repeated relapses, the surface of the cyst is often grayed out due to scarring.
