Sialadenitis (sialoadenitis) is inflammation of salivary glands, usually the major ones, the most common being the parotid gland, followed by submandibular and sublingual glands. [1] It should not be confused with sialadenosis (sialosis) which is a non-inflammatory enlargement of the major salivary glands. [2]
Sialodochitis (also termed ductal sialadenitis), [1] is inflammation of the duct system of a salivary gland. [2] This is compared to sialadenitis, which is inflammation of the gland parenchyma. [3] Sialodochitis may be associated with salivary duct strictures and salivary stones. [4] It is common in both the parotid glands and submandibular ...
Sialolithiasis refers to the formation of calculi within a salivary gland. If a calculus forms in the duct that drains the saliva from a salivary gland into the mouth, then saliva will be trapped in the gland. This may cause painful swelling and inflammation of the gland. Inflammation of a salivary gland is termed sialadenitis. Inflammation ...
Mucous extravasation phenomenon is a swelling of connective tissue consisting of a collection of fluid called mucus. This occurs because of a ruptured salivary gland duct usually caused by local trauma (damage) in the case of mucous extravasation phenomenon and an obstructed or ruptured salivary duct in the case of a mucus retention cyst. The ...

If the lesion is deeper, then there is a greater thickness of tissue separating from the oral cavity and the blue translucent appearance may not be a feature.
A salivary diverticulum (plural diverticuli) is a small pouch or out-pocketing of the duct system of a major salivary gland. [16] Such diverticuli typically cause pooling of saliva and recurrent sialadenitis , [ 17 ] especially parotitis . [ 18 ]
Blockage, whether caused by salivary duct stones or external compression, may cause pain and swelling of the parotid gland . Koplik's spots which are pathognomonic of measles are found near the opening of the parotid duct. The parotid duct may be cannulated by inserting a tube through the internal orifice in the mouth. [2]
Parotitis presents as swelling at the angle of the jaw. Bacterial parotitis presents as a unilateral swelling, where the gland is swollen and tender and usually produces pus at the Stensen's duct. This pus is usually sampled and the bacteria within are identified. Common causative bacteria are Staphylococcus aureus, Streptococcus pyogenes and E ...
