Psoriasis is a complex condition that manifests in various forms, each with its own set of symptoms. The most common type is plaque psoriasis, which accounts for about 80-90% of cases. This form is characterized by raised, red patches covered with a silvery-white buildup of dead skin cells. These patches, known as plaques, often appear on the elbows, knees, scalp, and lower back. They can be itchy, painful, and sometimes crack and bleed.
Another type is guttate psoriasis, which often starts in childhood or young adulthood. It appears as small, dot-like lesions on the skin, usually triggered by a bacterial infection such as strep throat. Inverse psoriasis, on the other hand, affects skin folds like the armpits, groin, and under the breasts. It appears as smooth, red patches that may worsen with friction and sweating.
Pustular psoriasis is a rare form characterized by white pustules surrounded by red skin. It can be localized to certain areas or widespread across the body. Erythrodermic psoriasis is the least common but most severe form, causing widespread redness and shedding of the skin. This type can be life-threatening and requires immediate medical attention.
Psoriasis can also affect the nails, causing pitting, thickening, and abnormal nail growth. In some cases, it leads to psoriatic arthritis, a condition that causes joint pain, stiffness, and swelling. Recognizing these symptoms early can help in managing the condition effectively.
