What type of lesion is characterized by scratch marks produced by mechanical force?

  1. Primary Lesions

  2. Secondary Lesions

  3. Inflammatory Lesions

  4. Vascular Lesions

The correct answer is: Secondary Lesions

The correct answer is secondary lesions, which are defined as changes in the skin that result from the progression of a primary lesion or from the manipulation of the skin, such as scratching. Scratch marks, also known as excoriations, are a direct result of an external mechanical force acting upon the skin, which can alter the appearance and texture of the affected area. Secondary lesions typically develop following primary lesions, like vesicles or papules, and represent the skin's response to injury, irritation, or trauma. Primary lesions are the initial response to a disease process and are characterized by their own distinct features without any preceding skin alteration. Inflammatory lesions refer specifically to changes in the skin that are linked to inflammation, such as redness, swelling, or heat, rather than mechanical damage. Vascular lesions are related to blood vessels and include conditions such as hemangiomas or telangiectasias, which do not derive from mechanical scratching or injury.
