Which of the following is NOT listed as a skin lesion type in the guidelines?

• A. Scar
• B. Plaque
• C. Vesicle
• D. Nodule

Answer: (A)

Skin lesions are categorized as primary versus secondary. The guidelines typically list primary lesion types that describe what is seen on the skin at the moment, such as plaque (a raised, flat-topped area), vesicle (a small fluid-filled blister), and nodule (a solid, deeper lump). A scar, on the other hand, is a secondary lesion—the fibrous tissue that forms after a wound has healed. Because the question asks which is NOT listed as a skin lesion type in the guidelines, scar is the best answer since it represents healing changes rather than a current primary lesion. Understanding this distinction helps you describe what you observe accurately: the present lesion’s primary characteristics, while recognizing scars reflect past injury and healing.
