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]
Angiomas are benign tumors derived from cells of the vascular or lymphatic vessel walls (endothelium) or derived from cells of the tissues surrounding these vessels. [ 1 ] [ 2 ] Angiomas are a frequent occurrence as patients age, but they might be an indicator of systemic problems such as liver disease.
It is caused by either Bartonella henselae or B. quintana. [2]B. henselae is most often transmitted through a cat scratch or bite, [3] though ticks and fleas may also act as vectors.

Angiokeratoma may be classified as: Angiokeratoma of Mibelli (also known as "Mibelli's angiokeratoma," [4] "Telangiectatic warts" [5]) consists of 1- to 5-mm red vascular papules, the surfaces of which become hyperkeratotic in the course of time.

The origin of tufted angiomas is not clear but markers on the cells suggest a possible derivation from the endothelial cells of lymph vessels. [11] They are also associated with the local secretion of growth factors that affect angiogenesis and promote the development of vascular lobules.
Patients usually have no symptoms at all, with no bleeding, discomfort, or inflammation related to the lesions, which mostly affect the lower limbs. [3] Nonetheless, there have been sporadic cases of angioma serpiginosum in the face, hands, feet, and mucous membranes , among other places.
