What condition is characterized by an abnormal growth of skin cells leading to thick, scaly patches?

The condition characterized by an abnormal growth of skin cells leading to thick, scaly patches is psoriasis. This chronic autoimmune disorder accelerates the life cycle of skin cells, causing them to multiply excessively. As a result, skin cells build up on the surface of the skin, forming the thick, silvery scales and red patches that are typically associated with psoriasis.

This condition can vary in severity and often goes through cycles of flare-ups and remissions. The excessive skin growth can lead to discomfort, itching, and even pain, significantly impacting a person's quality of life. Understanding this mechanism is essential for providing the appropriate treatment and management strategies to those affected.

In contrast to psoriasis, conditions like dermatitis, eczema, and vitiligo involve different underlying processes and manifestations. Dermatitis and eczema generally present with inflammation, redness, and itching but do not specifically cause the thick, scaly patches associated with psoriasis. Vitiligo, on the other hand, is characterized by the loss of skin pigmentation rather than the abnormal growth of skin cells.
