Which of the following is NOT an example of sundry skin lesions?

Macules are distinctly different from the other options listed as they are flat, discolored spots on the skin that do not have a change in texture or elevation. They are typically less than 1 centimeter in diameter and do not involve a buildup of material or a surface change in the skin.

In contrast, crusts, fissures, and scabs all represent different forms of lesions that occur due to clinical changes in the skin's surface. Crusts refer to dried serum, blood, or pus that can accumulate on the skin surface. Fissures are cracks or splits in the skin, often extending into deeper layers, while scabs are another form of crust that specifically results from the healing process over a wound. These characteristics distinguish macules as non-lesion examples within the context provided.
