Which of the following is a characteristic symptom of psoriasis?

• A. Oily skin
• B. Red, flaky patches
• C. Darkened skin spots
• D. Patchy hair loss

Answer: (B)

Psoriasis is a chronic autoimmune condition characterized by the rapid proliferation of skin cells, leading to the formation of scales and red, inflamed patches on the skin. This symptom is primarily due to an overreaction of the immune system, which causes skin cells to multiply more quickly than normal. The resulting plaques are often covered in silvery scales and can be itchy or painful. The distinct appearance of red, flaky patches is a hallmark of this condition and can appear on various parts of the body, including the elbows, knees, and scalp. Therefore, recognizing red, flaky patches as a key symptom of psoriasis is essential for diagnosis and management of the disease.
