Which condition is noted for having pruritic, purple, polygonal planar papules and plaques?

• A. Psoriasis
• B. Lichen Planus
• C. Behcet's Disease
• D. Calcaneovalgus

Answer: (B)

The condition characterized by pruritic, purple, polygonal planar papules and plaques is lichen planus. This condition is an inflammatory skin disorder that can present with flat-topped, itchy bumps that often appear in clusters. The lesions are known for their distinctively purple color and can also have a shiny, glazed appearance. Lichen planus can involve various areas of the body, including the skin, mucous membranes, and nails, and is often recognized through its classic presentation. In contrast to other options, psoriasis is usually associated with thick, red, scaly plaques, and although it can be itchy, the lesions differ in color and texture from those of lichen planus. Behcet's Disease is a systemic condition that can cause numerous symptoms, including oral and genital ulcers, but does not typically present with the pruritic, purple papules characteristic of lichen planus. Calcaneovalgus refers to a foot deformity and is unrelated to skin conditions, making it an irrelevant choice. Therefore, lichen planus is the correct answer due to its defining clinical features.
