Schamberg's disease, (also known as "progressive pigmentary dermatosis of Schamberg", [1] "purpura pigmentosa progressiva" (PPP), [1] and "Schamberg's purpura" [1]) is a chronic discoloration of the skin found in people of all ages, usually only affecting the feet, legs or thighs or a combination. It may occur as a single event or subsequent ...
Blue toe syndrome is a situation that may reflect atherothrombotic (clots resulting from the build-up of fats, cholesterol, and other substances in and on the artery walls) [1] microembolism, causing transient focal ischaemia, a temporary blockage of blood flow to the brain or spinal cord, [2] occasionally with minor apparent tissue loss, but without diffuse forefoot ischemia.

Raynaud syndrome, also known as Raynaud's phenomenon, is a medical condition in which the spasm of small arteries causes episodes of reduced blood flow to end arterioles. [1] Typically the fingers, and, less commonly, the toes, are involved. [1] Rarely, the nose, ears, nipples, or lips are affected. [1]
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 ().
The condition, which can be a disease, syndrome or phenomenon, causes blood vessels to narrow in response to cold or stress so that little or no blood flows to the affected body parts — most ...
Lipedema was first identified in the United States, at the Mayo Clinic, in 1940. [ 32 ] [ 33 ] Most attribute the original identification of lipedema to E. A. Hines and L. E. Wold (1951). [ 32 ] Despite that, lipedema is barely known in the United States to physicians or to the patients who have the disease.
In a 1985 paper published in the Journal of the American Medical Association, McCarty and colleagues first described a case series of patients with this disorder, for which they coined the abbreviation RS3PE. [16] RS3PE was initially thought to represent a form of seronegative rheumatoid arthritis but is now believed to be a separate syndrome. [8]
Chilblain lupus erythematosus is characterized by a rash that primarily affects acral surfaces that are frequently exposed to cold temperatures, such as the toes, fingers, ears, and nose. The rash is defined by oedematous skin, nodules , and tender plaques with a purple discoloration.
