Chronic condition presents as red patches covered with silvery scales, possibly autoimmune in nature. What is it called?

The condition described is psoriasis, which is characterized by red patches covered with silvery scales. This chronic skin condition is known to be autoimmune in nature, wherein the immune system mistakenly attacks healthy skin cells, leading to accelerated cell turnover. This results in the thickened patches of skin that are characteristic of psoriasis, often found on areas such as the elbows, knees, scalp, and lower back.

Psoriasis can vary in severity and is often associated with other health conditions, including arthritis. Although its exact cause is not fully understood, genetic factors play a significant role. In contrast, the other conditions listed have different presentations and underlying mechanisms. For instance, acne vulgaris primarily involves clogged pores and inflammation due to bacteria and oil; atopic dermatitis is an itchy, inflammatory skin condition often associated with allergies; and rosacea presents with facial redness and visible blood vessels but does not have the scaling seen in psoriasis.
