Cherry angioma, also called cherry hemangioma [1] or Campbell de Morgan Spot, [2] is a small bright red dome-shaped bump on the skin. [3] It ranges between 0.5 – 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age. [3] [4] If scratched, they may bleed. [5]
Blood blisters can also arise from forcible human contact, including grappling. Blood blisters also may occur with friction caused by constant rubbing of skin against a surface. Ill-fitting shoes that rub on the skin can cause the blood vessels in the skin to break and form a blood clot under the skin, resulting in a blood blister.
A petechia (/ p ɪ ˈ t iː k i ə /; [1] pl.: petechiae) is a small red or purple spot (≤4 mm in diameter) that can appear on the skin, conjunctiva, retina, and mucous membranes which is caused by haemorrhage of capillaries. [2] [3] The word is derived from Italian petecchia 'freckle', of obscure origin. [1]
A spider angioma or spider naevus (plural: spider naevi), also nevus araneus, is a type of telangiectasis [2] (swollen, spider-like blood vessels on the skin) found slightly beneath the skin's surface, often containing a central red spot and deep reddish extensions (see Blood color) which radiate outwards like a spider's web or a spider's legs.
This skin cancer tends to grow slowly and isn’t life-threatening for most people, but it needs to be treated before it can grow deep and injure nerves and blood vessels, the AAD noted.
Blood constitutes about eight percent of a person's weight (normally about five liters), and it circulates near the surface of the skin. Almost all trauma to the body, therefore, results in the shedding of blood. Its red color makes it readily apparent at crime scenes, and its residues are very difficult to completely remove.
A blood blister usually forms when a minute blood vessel close to the surface of the skin ruptures (breaks), and blood leaks into a tear between the layers of skin. This can happen if the skin is crushed, pinched or aggressively squeezed.
