Ichthyosis Pityriasis

Ichthyosis pityriasis

Ichthyosis, a disease characterized by the formation of scales, causes dry and flaky patches of skin, often leaving red contact ecchymosis, especially in folds and around joints. The disease is characterized by acantholysis and the presence of a keratin canal orifice (affected hair follicle), within which there is hyperkeratosis. Some forms of the disease (ichthyosiform erythroderma, ichthyosiform ablative dermatitis) can be complicated by infection and fungal infection. People with ichthyosis are at risk of developing secondary syphilis, which is associated with bleeding tendency

Atrophic ichthyosis, or scabby ichthyosis (**lamydes iranica**)

Classification The species was first described in 1758 by Count de Brogniart, a professor at the University of Edinburgh. There are many types of ichthyosis, they differ depending on the causes of their appearance - external and internal. Therefore, it is correct to speak specifically about ichthyosis, and not about ichthyoses in the singular. They are distinguished by the degree of skin damage, localization, and form of the disease. Atrophic ichthyosis is classified as a severe, slowly progressive form. Popularly it has a nickname from scars, “scab” comes from the word parsit - to wash with your hands in old Russian speech. But scab occurs only on affected areas of the skin, which are often inflamed. In Europe, the species was first described in the middle of the 17th century. The French physician J. M. de Charpentier established family ties with seborrheic and pityriasis species. Zorin showed that ichthyosis represents two independent forms; the disease is characteristic of the peoples of India, Africa, the USSR, and the eastern peoples of Europe. Similarities with seborrhea and dermodystrophy, hyperkeratosis were established. Later, the disease was named “ichthyosis of Irtiq”, in honor of the island in the Mediterranean Sea where the people in whom it was first discovered live. Doctors examine the skin according to indications when symptoms of a dermatological nature are presented. Indirect reasons indicating the disease are health problems. Often the causes cannot be precisely determined. The main provoking factors are injuries, inflammatory processes, mechanical damage to the epidermis, endocrine pathologies, fungal and viral infections, and heredity. The shape can be determined by microscopic examination of the skin. Some patients seek treatment before the causes are identified. Microscopy allows you to make a diagnosis without examining the patient. Thickening of the stratum corneum is not a characteristic feature for atrophic ichthyosis. Often, rashes appear at the site of contact with an irritant or substance that causes an allergic reaction. The pityriasis form affects children's skin. The upper stratum corneum of the skin is examined. If this procedure does not allow an accurate diagnosis to be made, a biopsy is performed. The disease is inherited and can occur under the influence of a certain physiological reaction of the body.
