Primary Lesions in Medicine

11.15.2011 · Posted in Beauty Articles

Primary skin lesions are variations in color or texture that may be present at birth, such as moles or birthmarks, or that may be acquired during a person’s lifetime, such as those associated with infectious diseases (warts, acne, or psoriasis), allergic reactions (hives or contact dermatitis), or environmental agents (sunburn, pressure, or temperature extremes).

nMacules are a change in skin color, without elevation or depression and, therefore, nonpalpable, well or ill-defined, variously sized but, by convention, less than one centimeter in diameter at the widest point. This wound is easy to notice due to the color difference in comparison to normal skin, and may be white, blue, or red. Macules may be the result of hyperpigmentation, hypopigmentation, vascular abnormalities, capillary dilatation, or purpura. They can be treated using whitening products.
n
nPatches are a large macule similar or greater than 1cm in diameter.
n
nPapules are a circumscribed, solid elevation of skin with no visible fluid, varying in size from a pinhead to 1cm. They can be brown, purple, pink or red in color. Papules may open when scratched and become infected and crusty. They can be induced by localized cellular reaction to the process of acne, and can be eased with a natural skin treatment.
n
nPlaques are a broad papule, equal to or greater than 1cm. They are a consequence of psoriasis and granuloma annulare. Creams can reduce the itching of this lesion and are available without a prescription.
n
nVesicles are a circumscribed, fluid-containing epidermal elevation that can vary from 1 to 10 mm in size. Vesicles are characteristic of ****** infections, acute allergic contact dermatitis, and some autoimmune blistering disorders. They can be smoothed with lotions.
n
nBullae are a rounded or irregularly shaped blister containing serous or seropurulent fluid, greater than 1cm in diameter. Burns, bites, irritant or allergic contact dermatitis, and drug reactions can result in Bullae.
n
nPustules are a small elevation of the skin containing purulent liquid usually consisting of necrotic inflammatory cells. Pustules are collections of neutrophils. They may arise in some inflammatory diseases including pustular psoriasis. Treatment may involve medications, ultraviolet light A, creams or ointments.
