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]
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]
4. Recurrent painful swellings – indicative of chronic recurrent sialadenitis, may have similar signs and symptoms to an acute episode. 5. Pus exudation from salivary gland openings – indicative of bacterial infection, may occur on manipulation of the affected gland or spontaneously. Other common diagnostic factors. 1.
The exact cause of the condition is unknown. [ 4 ] [ 5 ] There is most evidence to support vascular infarction and ischemic necrosis of salivary gland lobules as a mechanism for the condition. [ 6 ] Experimentally, local anaesthetic injections and tying of the arteries is reported to trigger the development of tissue changes similar to NS in ...

Less commonly the parotid gland or rarely the sublingual gland or a minor salivary gland may develop salivary stones. The usual symptoms are pain and swelling of the affected salivary gland, both of which get worse when salivary flow is stimulated, e.g. with the sight, thought, smell or taste of food, or with hunger or chewing.
Known as a "superficial mucocele", this type presents as single or multiple vesicles and bursts into an ulcer. Despite healing after a few days, superficial mucoceles recur often in the same location. Other causes of bumps inside lips are aphthous ulcer, lipoma, benign tumors of salivary glands, submucous abscesses, and haemangiomas.
The cause and pathogenesis of this chronic condition are not very well understood. Several factors have been postulated: Formation of a hard salivary calculus or sialolith by accumulation of calcium salts in the duct of the salivary gland (a process known as Sialolithiasis). This has been proposed as the most common cause for Küttner's tumor ...
