It is characterized by a mucous swelling located under the mucosa, about the size of soybeans, and a translucent, painless blister. After the rupture, the mucus can flow out, the swelling subsides, but it can relapse soon. After multiple recurrences, the surface of the cyst is often grayish white due to scarring. According to the cluster of blister spots at the junction of skin and mucous membranes, the symptoms are light, and the surface of the skin lesions has a burning sensation. Short course of disease, repeated recurrence, and occurrence of fever or gastrointestinal dysfunction can be diagnosed.

Cause

Although there is no obvious reason to be found, the mucous gland duct is often broken due to mild trauma, and salivary mucin is spilled into the submucosal tissue or lamina propria. Also seen in glandular cheilitis, due to hyperplasia of the lip and mucosa glands and ducts. The possibility of viral infections, oral ulcers and other diseases, as well as the effects of spicy diets, is more likely to be caused by viral infections.
