Psoriasis is a specific skin disease that is chronic and recurrent. It affects over 100 million people worldwide, approximately 3-4% of the population in the Western world (about 2.5 million in Italy). It presents in various forms but is absolutely not contagious. This pathology occurs when the immune system mistakenly identifies skin cells as a pathogen and sends faulty signals that accelerate the skin cell growth cycle. There are five types of psoriasis. The most common form, plaque psoriasis, typically appears as red and white scaly patches on the outer layer of the epidermis. In plaque psoriasis, the skin rapidly accumulates at these sites, giving it a white-silver appearance. The plaques often occur on the skin of the elbows and knees. They can affect any area, including the scalp, palms of the hands, soles of the feet, and genitals.
Psoriasis: from the Greek “psora” (itch)
However, some patients may not have any dermatological signs or symptoms. Psoriasis is derived from the Greek “psora,” meaning “itch”: sometimes in the areas where the patches appear, there is a more or less intense itch, depending on the individual’s reaction to inflammation. At the root of the disease is a genetic alteration that is inherited, with the involvement of environmental and psycho-emotional triggering factors.It is a condition that can cause discomfort and have a significant negative impact on quality of life. It can develop at any age (even in the first months of life), but predominantly between the second and third decades of life. As of today, there is no definitive cure or one treatment that is better than another, but it can be managed with appropriate care strategies. It is advisable to consult a specialist: each patient responds differently to the therapy chosen by the doctor.
