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.
If located near the eye, a growing hemangioma may cause an occlusion or deviation of the eye that can lead to amblyopia. [23] Very rarely, extremely large hemangiomas can cause high-output heart failure due to the amount of blood that must be pumped to excess blood vessels. Lesions adjacent to bone may cause erosion of the bone. [18]
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.
People with coronary artery disease, or narrowing of the blood vessels supplying their heart, may develop symptoms such as: Chest pain that often gets worse with stress or physical activity ...
A vascular anomaly is any of a range of lesions from a simple birthmark to a large tumor that may be disfiguring. They are caused by a disorder of the vascular system. [1] A vascular anomaly is a localized defect in blood vessels or lymph vessels. These defects are characterized by an increased number of vessels, and vessels that are both ...
This causes vasodilation, the dilation of blood vessels, causing blood to pool or collect in the affected area. [9] Over time, port-wine stains may become thick or develop small ridges or bumps, and do not fade with age. [2] Such birthmarks may have emotional or social repercussions. [2]
Hereditary pyropoikilocytosis (HPP) is an autosomal recessive form of hemolytic anemia which typically presents at infancy or early childhood, characterized by abnormal red blood cell morphology including "budding red cells, fragmented red cells, spherocytes, elliptocytes, triangular cells, and other bizarre-shaped red cells."
Cutaneous small-vessel vasculitis (CSVV) is inflammation of small blood vessels, usually accompanied by small lumps beneath the skin. [1]: 831 [2] The condition is also known as hypersensitivity vasculitis, cutaneous leukocytoclastic vasculitis, hypersensitivity angiitis, cutaneous leukocytoclastic angiitis, cutaneous necrotizing vasculitis and cutaneous necrotizing venulitis, [3]
