Correct Answer is ["A","B","C"]
Explanation
Choice A rationale
Scales represent the accumulation of dead skin cells that flake off, a common secondary lesion in eczema resulting from the chronic inflammation and rapid skin cell turnover.
Choice B rationale
Erosion occurs when the superficial layer of skin is lost, typically due to scratching or friction in eczema, exposing the underlying epidermis and sometimes leading to infection.
Choice C rationale
Crusts form when serum, blood, or purulent exudate dries on the skin surface, often seen in eczema as a result of weeping lesions and subsequent drying.
Choice D rationale
Ulcers are deeper lesions extending into the dermis or subcutaneous tissue and are not typically associated with eczema. Eczema usually affects the epidermis, causing secondary lesions like scales, erosion, and crusts rather than deep tissue ulcers.
