Epidemiological and statistical data concerning such a disease as salivary gland tumor have not been registered until recently. The main reasons for this fact were: lack of separate statistical records; association with other malignant neoplasms of the upper digestive tract, as well as statistical errors, demographic differences and other local factors.
Tuberculosis of the salivary glands (synonym: tuberculosis) is an infectious disease caused by Mycobacterium tuberculosis and characterized by the formation of specific granulomas in various organs and tissues (most often in the lungs) and a polymorphic clinical picture.
Syphilis of the salivary glands (salivary gland lues) is a chronic venereal disease caused by pale treponema, characterized by lesions of the skin, mucous membranes, internal organs and nervous system.
Cystic lesions most often occur in the minor salivary glands, less often in the parotid and submandibular salivary glands. The provoking factor may be trauma to the gland duct, leading to its atresia and accumulation of contents. The accumulation, increasing, presses on the walls of the cavity, increasing the cavity of the salivary gland cyst.
Acinic cell carcinoma of the salivary gland was initially considered a serous cell adenoma. However, in 1954, Foote and Frazel found that this tumor is aggressive, has infiltrative growth, and metastasizes.
Adenoma of the salivary gland ranks first among benign tumors. The term "mixed tumor" proposed by R. Virchow in 1863 reflects the opinion held by many pathomorphologists, supporters of epithelial and mesenchymal tumor development.
A sebaceous nevus is a hamartoma of the sebaceous glands, usually present from birth, but there have been cases where this developmental defect was latent until puberty and only became clinically apparent with the onset of the latter.
Sagittal, or vertical, fractures of the cervical vertebrae are a special, rare type of compression comminuted fractures of the cervical vertebrae.
Sagging of the nasal septum is usually caused by excess of its skin part. As a result, the nostrils are wide open and the anterior part of the mucous membrane of the nasal septum is visible through them.
Saddle-shaped depression of the nasal bridge can be localized only in the bony or membranous part of the septum or simultaneously in both.
Sactosalpinx is a complex disease that causes numerous disorders in a woman's body, negatively affecting the ability to get pregnant and give birth to a child.
