Schamberg's disease is a skin disorder that causes a discoloration of the lower extremities. [4] It usually occurs in the lower extremities and rarely elsewhere. [4] This condition is caused by leaky blood vessels near the surface of the skin. [7] The cause of the leaky capillaries is usually not known. [7]
Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
Striae, or "stretch marks", begin as reddish or purple lesions which can appear anywhere on the body, but are most likely to appear in places where larger amounts of fat are stored. The most common places are the abdomen (especially near the navel ), breasts, upper arms, underarms, back, thighs (both inner and outer), hips, and buttocks.
Purpura (/ ˈ p ɜːr p jʊər ə / [1]) is a condition of red or purple discolored spots on the skin that do not blanch on applying pressure. The spots are caused by bleeding underneath the skin secondary to platelet disorders, vascular disorders, coagulation disorders, or other causes. [2]
Flow abnormalities in smaller veins known as reticular veins or feeder veins under the skin can also cause spider veins to form, thereby making a recurrence of spider veins in the treated area less likely. Factors that predispose to the development of varicose and telangiectatic leg veins include Age
Other comorbidities may also be the root cause of venous ulcers. [12] It is in the crus that the classic venous stasis ulcer occurs. Venous stasis results from damage to the vein valvular system in the lower extremity and in extreme cases allows the pressure in the veins to be higher than the pressure in the arteries.
DVT usually occurs in the veins of the legs, although it can also occur in the veins of the arms. Immobility, active cancer, obesity, traumatic damage and congenital disorders that make clots more likely are all risk factors for deep vein thrombosis. It can cause the affected limb to swell, and cause pain and an overlying skin rash.
There is a recurrent acute and chronic inflammation and thrombosis of arteries and veins of the hands and feet. The main symptom is pain in the affected areas, at rest and while walking (claudication). [1] The impaired circulation increases sensitivity to cold. Peripheral pulses are diminished or absent. There are color changes in the extremities.
