Systemic vasculitis is a heterogeneous group of diseases, the main morphological feature of which is inflammation of the vascular wall, and the spectrum of their clinical manifestations depends on the type, size, location of the affected vessels and the severity of the accompanying inflammatory changes.
Systemic scleroderma is a polysyndromic autoimmune disease characterized by progressive fibrosis and widespread vascular pathology such as obliterating microangiopathy, which underlie generalized Raynaud's syndrome, skin lesions, and internal organs (lungs, heart, gastrointestinal tract, kidneys).

Systemic lupus erythematosus is a systemic autoimmune disease of unknown etiology, which is based on a genetically determined disorder of immune regulation, which determines the formation of organ-nonspecific antibodies to cell nuclear antigens with the development of immune inflammation in the tissues of many organs.

Inflammation is a typical protective reaction to local damage. The evolution of views on the nature of inflammation largely reflects the development of fundamental general biological concepts about the body's response to the effects of damaging factors.
Liver diseases often present with general symptoms and disturbances.
Syringoma (syn.: multiple syringoadenoma, eruptive hidradenoma) is a developmental defect of the eccrine sweat gland, similar in its structure to the ductal section in the upper part of the dermis.
Primary syphilis, which manifests itself as a chancre, is very rare and occurs as a result of accidental infection of the auricle or external auditory canal through damage to the skin or through kissing.
Syphilitic hepatitis occurs in 4-6% of patients with late visceral syphilis. Syphilitic liver lesions can be congenital and acquired.
Syphilis is a chronic infectious disease transmitted primarily through sexual intercourse. It is characterized by periodicity of the course and various clinical manifestations.

If in the first half of the 20th century syphilis of the pharynx was extremely rare, then in the last decade of the last century and at the beginning of the 21st century the number of this localization of syphilis has been steadily growing, as has the total number of genital forms of this venereal disease. Due to the large morphological diversity of tissues that make up the pharynx, its lesions by syphilis are distinguished by a number of features that are not inherent in other localizations of this disease.

Syphilis of the larynx is observed much less frequently than of the nose or pharynx. The larynx is extremely rarely affected by congenital syphilis.
Syphilis of the esophagus is a disease that is not so common, occurring in all stages of this venereal disease, but most often manifesting itself in the tertiary period.
Unusual serologic responses have been observed in HIV-infected patients with syphilis. Most reports indicate higher than expected titers, but false negatives and delayed onset of seroreactivity have also been reported.
All women should be screened for syphilis early in pregnancy. In populations where optimal prenatal care is not available, screening with the RPR test and treatment (if positive) should be performed at the time of pregnancy detection.

Bejel (endemic syphilis, Arabic syphilis) is a chronic infectious disease that occurs mainly among children and is manifested by erythematous-papular rashes on the skin, lesions of the mucous membranes, bones, joints and cartilage.

Synovitis of the knee joint is a common disease that is associated with inflammation of the articular connective tissue (synovial membrane).

Synesthesia is a relatively rare phenomenon and its mechanisms are not fully understood.

Polyglandular deficiency syndromes (autoimmune polyglandular syndromes; polyendocrine deficiency syndromes) are characterized by competitive dysfunction of several endocrine glands.
Syndrome X is a dysfunction or constriction of the vessels of the microcirculatory bed, leading to the appearance of an attack of angina pectoris (angina).
Syndactyly is a congenital malformation of the hand, consisting of the fusion of two or more fingers with a violation of the cosmetic and functional state. This anomaly is sometimes observed in isolation, in which case the malformation can be considered a diagnosis. In these cases, the fingers are fully developed, but there is a soft tissue or bone fusion between them.
