What is the medical term for redness of the skin?

  1. Hyperemia

  2. Erythema

  3. Dermatitis

  4. Edema

The correct answer is: Erythema

The medical term for redness of the skin is erythema. This condition occurs when blood vessels in the skin dilate or expand, often resulting in a warm, red appearance. Erythema can be caused by various factors including inflammation, infection, allergic reactions, or increased circulation to the area. Conditions that lead to erythema are often associated with some form of irritation or damage to the skin, allowing for a clearer understanding of its underlying causes. Hyperemia refers to an excess of blood in a particular area but is not exclusively concerned with the skin's redness; it can occur in any tissue. Dermatitis is a broader term that refers to inflammation of the skin, often characterized by redness but also involving other symptoms like itching and swelling. Edema specifically describes the accumulation of fluid in tissues, leading to swelling, rather than redness. This distinction between erythema and these other terms highlights why erythema is the correct term for the redness of the skin specifically.
