Mucinous gland cyst

Mucous gland cysts are a common disease of the oral mucosa. They are superficial cysts formed by the retention of secretions after the small salivary ducts are blocked. Mainly due to minor trauma, the salivary gland ducts are ruptured; salivary protein overflows into the tissue, followed by the mucous gland ducts being blocked; mucus retention causes the gland ducts to expand, which often occurs in the lip mucosa, followed by the buccal mucosa, The tongue and abdomen mucosa, but the lower lip is more common. Clinical manifestations The mucinous gland cyst is located under the mucosa, about the size of a soybean, and appears as a translucent painless vesicle. After rupture, mucus can flow and the swelling subsides, but it can soon return. After repeated relapses, the surface of the cyst is often grayed out due to scarring. Treatment often involves surgical resection and iodine injection. Mucus gland cysts can occur in three pairs of large salivary glands and all small salivary glands. There are two types of retention cysts and congenital cysts. Retention cysts are the most common. They often occur in the sublingual and small salivary glands, followed by the parotid glands. Submandibular gland cysts are very rare. They are caused by narrowing of the catheter or obstruction of the duct caused by tumors, calculus, injuries, parasites, etc. This condition is an intermittent obstruction. When there is no inflammation, the proximal glands of the catheter The vesicles expand and form retention cysts. Congenital cysts are more common in the parotid gland. They are developed due to the development of epithelial components left in deep tissues during embryonic development. Retention cysts that occur in the small salivary glands are called mucous gland cysts. Nomenclature, namely sublingual cyst, submandibular cyst and parotid cyst.
