Detect skin diseases through images
Recognizing skin diseases by their specific symptoms is often not that easy. Redness, spots or itchy rashes are signs of many different skin diseases. Nevertheless, completely different causes can be behind similar-looking symptoms. For example, skin diseases can be caused by psychological problems, pathogens, fungi or allergies, but also by numerous other causes.
Shingles (Herpes Zoster)
The infectious disease shingles is caused by the varicella zoster virus, is often initially thought to be a skin disease. It manifests itself with very different symptoms. In addition to general exhaustion, burning and stabbing pain occurs. The typical, filled blisters on the skin are often preceded by itchy rashes.
Shingles can occur all over the body. However, the trunk, legs, arms, face or neck are most frequently affected by the rash and blisters. The rash usually spreads around the upper part of the body like a belt.
Rosacea (acne rosacea)
The face looks red and swollen, pustules cover the skin, red and blue veins cover large parts of the skin surface. Rosacea, a chronic and inflammatory skin disease of the face, is not curable. Feared complications are inflammation of the eyes. But there are various cosmetic and therapeutic options for the treatment of acne rosacea, which lead to a significant improvement.
Rosacea: cause unclear
Rosacea (rose blossom) is the flattering name for a skin disease which, in its advanced stages, literally disfigures the affected person, often isolates him or her and can lead to depression. It almost always affects men and women over the age of 40; fair-skinned types with red hair seem to be particularly susceptible – although scientists still cannot find the cause.
It is suspected that both an unstable vascular nervous system and microorganisms such as the hair follicle mite and liver diseases promote the disease. It is almost exclusively men who get growths on the sebaceous glands in the nose area, the so-called “bulbous nose” (rhinophyma). The disease can be hereditary, but it is not contagious.
Phases of rosacea
Rosacea only begins inconspicuously with redness of the skin. In particular, these occur under the influence of the following circumstances:
* emotional stress
* spicy food
The fine branched and superficial blood vessels are visibly and permanently dilated – it is said that the skin “blooms”. This still mild form of the disease is called “couperose”.
In the second stage, pustules and nodules as well as swellings appear in phases. These can become inflamed in the next stage and are sometimes purulent. The skin is swollen, reddened and large-pored and can get blackheads: The similarities with acne therefore sometimes lead to misdiagnosis.
The complications of rosacea include inflammation of the eyes. About one-fifth of patients affected get dry eyes, conjunctivitis, and sometimes corneal and iris inflammation.
