Red And Purple Marks On Skin

Red spots on the skin are a common medical complaint. When the spots occur in outbreaks, they are sometimes termed rashes. Rashes can occur due to infections of the skin, disseminated infections (that have spread throughout the body), allergic reactions, or irritations of the skin. When a red bump or rash is flat, it is medically known as a macule.

Dark spots, dots or patches are as a result of hyperpigmentation of the skin due to overproduction of skin pigment called melanin by melanocytes. Melanocytes are cells that produce melanin pigment that gives the skin its color.

Erythema is the medical term for redness of the skin. Red spots on the skin that occur singly can be a small benign tumor of blood vessels, known as a hemangioma. Tiny, pinpoint hemorrhages can be seen in the skin and are referred to as petechiae.

Petechiae are pinpoint-sized red dots under the surface of the skin. The dots are red because they contain blood that has leaked from tiny blood vessels (capillaries) into the skin. Petechiae may be an indication of a serious underlying problem that requires medical evaluation.

Petechiae are dark red dots like appearance all over the skin. The patches look like dots of blood clot. Though they are like rashes, they rarely itch.

Certain illnesses, including kidney disease, hyperthyroidism, and liver disease, may cause itching without rash as well. Certain kinds of cancer, such as lymphoma, may also result in itching skin with no rash.
