A ranula is a type of mucocele, and therefore could be classified as a disorder of the salivary glands. Usually a ranula is confined to the floor of the mouth (termed a "simple ranula"). [6] An unusual variant is the cervical ranula (also called a plunging or diving ranula), where the swelling is in the neck rather than the floor of the mouth. [1]
Canine gallbladder mucocele (GBM) is an emerging biliary disease in dogs described as the excessive and abnormal accumulation of thick, gelatinous mucus in the lumen, which results in an enlarged gallbladder. GBMs have been diagnosed more frequently in comparison to prior to the 2000s when it was considered rare. [1]
Salivary stones (sialolith) may be evident with cystic dilation of the salivary ducts and periductal fibrosis. Mucus extravasation may also be observed. Common observations of chronic sialadenitis include chronic inflammatory infiltrate (lymphocytes, plasma cells and macrophages), fibrosis, acinar atrophy, and mucous cell metaplasia of the ...
Oral mucocele a mucous cyst. Oral mucoceles are common, and are caused by rupture of a salivary gland duct and spillage of mucin into the surrounding tissues. Usually, they are caused by trauma. Classically, a mucocele is bluish and fluctuant, and most commonly occurs on the lower lip. [11] Ranula is a mucocele under the tongue.
Some mucoceles spontaneously resolve on their own after a short time. Others are chronic and require surgical removal. Recurrence is possible, thus the adjacent salivary gland may be excised as a preventive measure. Hence surgical removal of cyst is treatment of choice. [7] Several types of procedures are available for the surgical removal of ...
They are a relatively common complication following surgery to the salivary glands, [4] commonly parotidectomy (removal of the parotid gland). [5] In this case the sialocele is the result of saliva draining out of remaining parotid tissue, and occurs about 5 to 10% of cases of superficial (partial) parotidectomy. [5] [6]
Chronic sclerosing sialadenitis is a chronic (long-lasting) inflammatory condition affecting the salivary gland. Relatively rare in occurrence, this condition is benign, but presents as hard, indurated and enlarged masses that are clinically indistinguishable from salivary gland neoplasms or tumors.
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.
