Initially red to pink, flat spots (formally, "macules") and raised bumps (formally, "papules") may be seen on the skin. [5] [6] Once fully developed, the classic appearance is "non-blanching, palpable purpura". [6] [5] [7] This appears as deep red to purple spots that feel raised to the touch. Purpura refers to the red-purple discolored spots ...
Livedo reticularis is a common skin finding consisting of a mottled reticulated vascular pattern that appears as a lace-like purplish discoloration of the skin. [1] The discoloration is caused by reduction in blood flow through the arterioles that supply the cutaneous capillaries, resulting in deoxygenated blood showing as blue discoloration ().
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]
The classification of vascular anomalies is now based upon cellular features, natural history, and clinical behavior of the lesion. Vascular anomalies are divided into vascular tumors/neoplasms which include infantile hemangiomas, and vascular malformations that include entities with enlarged or abnormal vessels such as capillary malformations ...
Retiform purpura is a cutaneous morphology characterized by a branching , non-blanching patch, plaque, or lesion that develops when blood vessels supplying the skin become obstructed. [ 2 ] [ 3 ] This blockage leads to downstream cutaneous ischemia , or insufficient blood supply to the skin, causing purpura , necrosis , and potentially ...
The definite diagnosis of vasculitis is established after a biopsy of involved organ or tissue, such as skin, sinuses, lung, nerve, brain, and kidney. The biopsy elucidates the pattern of blood vessel inflammation. Some types of vasculitis display leukocytoclasis, which is vascular damage caused by nuclear debris from infiltrating neutrophils. [37]
A port-wine stain (nevus flammeus) is a discoloration of the human skin caused by a vascular anomaly (a capillary malformation in the skin). [1] They are so named for their coloration, which is similar in color to port wine, a fortified red wine from Portugal. A port-wine stain is a capillary malformation, seen at birth. [2]
A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. The most common form, seen in infants, is an infantile hemangioma, known colloquially as a "strawberry mark", most commonly presenting on the skin at birth or in the first weeks of life. A hemangioma can occur anywhere on the body, but most ...
