Which chronic disorder is characterized by excess skin cell production, forming thick, itchy, and painful patches?

• A. Eczema
• B. Psoriasis
• C. Dermatitis
• D. Acne

Answer: (B)

The condition characterized by excess skin cell production, leading to thick, itchy, and painful patches, is psoriasis. This chronic disorder results from an accelerated life cycle of skin cells, causing them to proliferate too quickly. As these skin cells build up on the surface, they form red, scaly patches that can be itchy and painful. Psoriasis is an autoimmune condition that not only affects the skin but can also have systemic implications, meaning it may be associated with other health issues.

In contrast, eczema is primarily an inflammatory condition that typically results in dry, itchy skin that may oozes or crusts rather than forming thick patches. Dermatitis refers to a broad category of skin inflammation but does not specifically imply the excessive skin cell production seen in psoriasis. Acne primarily involves pores being clogged due to excess oil and skin cells but does not present as thick patches; it manifests through pimples, blackheads, and cysts. Thus, psoriasis is distinctly recognized for its hallmark symptoms of psoriasis plaques caused by rapid skin cell turnover.
