Onychia Syphilitica

Syphilitic onychia: symptoms, causes and treatment

Onychia syphilitica, also known as syphilonychia, is a rare nail disease that occurs as a result of secondary syphilis. Secondary syphilis is a chronic infectious disease caused by the bacterium Treponema pallidum. Syphilitic onychia can affect one or more nails and is manifested by characteristic changes in their structure and appearance.

Symptoms of Onychia syphilitica include the following:

  1. Deformed nails: Affected nails may become thin, concave or convex.
  2. Onycholysis: peeling of nails from the nail plate.
  3. Formation of bony growths: Lumpiness or thickening may appear on the surface of the nails.
  4. Discoloration: Nails may take on a yellowish or grayish tint.
  5. Vulnerability: Affected nails may become brittle and break easily.

The cause of the development of syphilitic onychia is the spread of syphilis infection in the body and its subsequent effect on the nails. Syphilis is transmitted through sexual contact with an infected partner or from mother to child during pregnancy. If syphilis is left untreated, it can progress and cause secondary syphilis, including onychia syphilis.

Treatment of syphilitic onychia includes the following measures:

  1. Antibiotics: Special antibiotics are used to fight syphilis infection in the body. Treatment should be prescribed and supervised by a doctor.
  2. Nail care: Regular care of affected nails will help improve their condition. It is recommended to trim your nails carefully, avoiding injury and contact with external irritants.
  3. Avoiding self-medication: It is important to avoid self-medicating syphilis or onychia syphilis. Only a doctor can prescribe the correct treatment and monitor its effectiveness.

It is important to note that onychia syphilis is a rare complication of syphilis and can be prevented through the use of precautions such as the use of condoms during sexual intercourse and regular medical examinations to detect and treat syphilis in the early stages.

Syphilitic onychia is a skin pathology disease that is manifested by changes in the nail plate. This is a rather rare form of damage to the nail plate and is often found during complex treatment of syphilis. As a rule, the prognosis for complete recovery is favorable, however, such changes in the nail plates may require surgical treatment. That is why the treatment of the disease should be approached extremely carefully. The main cause of damage to the nail plate is considered to be the activity of pathogens of syphilitic infection. Also, such a violation of the plate, according to experts, can be the result of an infectious fungal infection due to a malfunction of the immune system. Such assumptions are confirmed by the manifestation of symptoms on the surface of the nails during the full course of treatment for syphilis. However, if there were no first factor provoking a violation of the structure of the nail plate, then such a pathology was often diagnosed as a failure of the immune system and developed only as a complication of infection with a syphilitic agent. In addition, there is a version according to which the problem of this disease occurs due to the presence of other infectious foci of localization - such as tuberculosis or pneumonia. IN
