Swollen salivary glands

Introduction Salivary gland cysts: The generalized mucus cysts include the mucus cysts of the Xiaochuan flow gland and the sublingual cysts, which are the more common salivary adenoma-like lesions. Parotid cysts are divided into two categories: retention and congenital. The former is rare. Benign hypertrophy of salivary glands, also known as salivary gland enlargement or salivary degeneration, is a non-tumor, non-inflammatory, chronic, recurrent, painless, swollen salivary gland disease.

Cause

Causes of salivary gland enlargement:

According to the etiology and pathological manifestations, it can be divided into external mucinous cysts and retention mucus cysts.

1. Extravasational mucinous cysts account for more than 80% of mucinous cysts. The tissue is characterized by mucinous granuloma or mucus-filled pseudocapsules without epithelial lining. Experimental studies suggest that extravasated mucinous cysts are caused by trauma.

2, retention of mucinous cysts with epithelial lining, retention of mucus mass and connective tissue capsule, the main cause of the disease is the obstruction of the catheter system, which can be caused by microscopic vermiculite, secretion concentration or bending of the catheter system.

Examination and diagnosis of salivary gland enlargement:

The clinical manifestations of benign hypertrophy of salivary glands are diffuse enlargement, softness, and often bilateral in the salivary glands; no redness in the ducts and no abnormal secretions. Patients may have diabetes, alcohol, malnutrition, and long-term medication history. Salivary gland angiography: no abnormalities in the ducts and acinus, volume increased significantly, and emptying function was slightly delayed. The salivary gland is well differentiated from salivary gland tumors and Sjogren's syndrome.

Patients with unilateral hypertrophy should be differentiated from salivary gland tumors. Ultrasound is the preferred method. The salivary gland is benign and hypertrophic, with no space-occupying lesions. Some patients with Sjogren's syndrome may have salivary gland enlargement, but they are often accompanied by symptoms such as dry mouth. Immunological tests may have autoantibodies, and salivary gland angiography may show characteristic changes of ducts and acinus.

Differential diagnosis

Differential diagnosis of salivary gland enlargement:

1, mucin cyst: occurs in the lower lip and the ventral side of the tongue. The cyst is located at the end of the year, and the surface is covered with only a thin layer of mucosa, so it is a translucent, pale yellow vesicle that resembles a blister. The texture is soft and flexible. The cyst is easily broken by the bite and flows out of the egg white-like clear viscous liquid, and the cyst disappears. After the rupture healed, it was filled with mucus and formed a cyst again.

2, sublingual cyst: common in adolescents, can be divided into 3 categories:

1 simple type: the majority. The cyst is located in the sublingual area and is light purple-blue. Often located on the bottom side of the mouth. A larger cyst can lift the tongue like a "heavy tongue." After the cyst has ruptured due to trauma, it flows out of a thick, slightly yellowish or egg-like liquid, and the cyst temporarily disappears. After the summer, the window heals and the cyst grows up as before;

2-port appearance: also known as latent projection. Mainly manifested as submandibular mass, while the fundus cyst is not obvious. The palpation is soft, non-adhesive to the skin and incompressible.

3 dumbbell type: for the above two types of mixing, that is, cystic mass can be seen in the sublingual area of the mouth and the mandibular area outside the mouth.
