Final answer:
The child with chronic itching and plaques in flexural areas is most likely presenting eczema, which is managed with moisturizers, corticosteroid creams, and immunosuppressants.
Step-by-step explanation:
A child with chronic, pruritic (itching) plaques in the flexural areas of the body is most likely presenting a condition known as eczema. Eczema, also referred to as atopic dermatitis, is a common skin disorder that is characterized by dry, itchy patches of skin that often appear as a red, flaky rash.
This inflammatory condition can be accompanied by swelling, flaking, and in severe cases, bleeding. Common areas affected include the elbows, knees, and in flexural areas such as behind the knees and the inside of elbows. Management of eczema symptoms usually includes the use of moisturizers, corticosteroid creams, and immunosuppressants to reduce inflammation and alleviate itching.
