There are a group of rare skin diseases that are not common among people, so what are they? What are the reasons for its occurrence? Here are the details in this article.
The skin is the largest organ in the human body, and there are many skin diseases, some of which are common and some that are rare, and this is what the following article will address, as we will talk about rare skin diseases, and their most important symptoms:

About some rare skin diseases
Having mentioned a number of rare skin diseases, we will explain about eight of them
1. Ringworm
It is a disease that causes severe itching when exposed to sunlight, and other symptoms include peeling of the skin, the appearance of small red skin granules, and small red plaques and nodules.
Exposed areas exposed to the sun are affected more than others by this disease, such as: the face, lips, neck, chest, arms, and hands, but it may affect anywhere in the body even if it is not exposed to direct sunlight.
2. Scaly skin syndrome
It is a genetic skin disorder caused by a genetic defect, and it arises from birth or early childhood.
In it, an accelerated outbreak of the outer skin layer occurs. This peeling does not cause pain, but it may cause itching, dryness and redness of the skin, and ulcers in the place of peeling.
3. Blau syndrome
This rare syndrome usually affects children under 4 years of age. It is caused by genetic abnormalities and has symptoms similar to sarcoidosis.
Symptoms include joint pain and inflammation, skin redness, dark patches on the skin, and eye inflammation and irritation.
4. Blow up
People with this disease suffer from a change in skin color due to the accumulation of silver salts in the body, which causes the skin to change color from blue to gray.
This disease occurs when a person ingests silver, either from food supplements or from exposure to silver, for example workers who work in silver factories and the metal alloy industry.
5. The red-forming portophoresis
The main cause of this disease is a metabolic defect, which occurs due to a genetic deficiency in an enzyme called ferrochelatase.
People with this disease suffer from skin sensitivity to sunlight, and there are symptoms that occur when exposed to the sun, such as: pain in the skin, and if the exposure period is long, redness and swelling of the skin occurs.
Ulcers and crusts may also occur in the skin, but at a lower rate, and over time, the thickness of the skin can increase and scarring occurs.
6. Colored sweat
People with tinted sweating have colored sweat that may be black, green, brown, yellow or blue, and it usually begins around puberty.
Symptoms also include a warm feeling on the skin before the secretion of colored sweat, and a tingling sensation in the skin.
Sweat can occur in the armpits, face, or the dark areola around the nipple.
7. Biological wear and tear
It is a skin rash that appears in the lower legs, usually affects diabetics and affects females more than males. The rash may be on the front or back of the leg, and it is painful or causes pain when pressed.
The shape of the rash can be oval, circular, or irregular in shape, and the rash often has a center in the middle with blood vessels, and these vessels can ulcerate if they are hit, which leads to inflammation.
8. Fish scale disease
In contrast to scaly skin disease, what happens here is a slowdown in the natural exfoliation process of dead skin cells, which causes their accumulation and thus the accumulation of keratin, which is the skin protein, which leads to severe dryness in the skin.
Dehydration causes scales similar to fish scales, scales on the scalp, and deep cracks, especially in the elbows and legs, and they can be very painful.
The disease can be transmitted through inheritance, and it may be linked to other diseases, such as: thyroid dysfunction, cancer, or human immunodeficiency virus (AIDS).
When should you see a doctor?
As we mentioned, there are rare skin diseases whose symptoms include itching, but not every itchy skin is a cause for concern. Rather, a doctor should be consulted when there is an itching in the following cases:
Itching spreads all over the body.
If itching is accompanied by a high temperature.
The itching came on suddenly and spread quickly.
Itching causes pain.
Itching causes bubbles.
