Peripheral edema condition. Successful treatment depends on control of the underlying cause. Severe swelling can cause permanent damage to nerves, resulting in peripheral neuropathy. Many cases from temporary or minor causes resolve on their own, with no lasting damage. Peripheral edema Peripheral edema is edema (accumulation of fluid causing swelling) in tissues perfused by the peripheral vascular system, usually in the lower limbs. In the most dependent parts of the body (those hanging distally), it may be called dependent edema. The condition is commonly associated with aging, but can be caused by many other conditions, including congestive heart failure, renal failure, liver
Reinke's edema cord fibroblasts. In normal tissue, these spindle-shaped CD34+ fibroblasts produce extracellular matrix proteins such as collagen and elastin. Recent findings have shown a morphological change in fibroblasts extracted from the tissue of Reinke's edema to a more dendritic-like shape with several protrusions. Large populations of these altered CD34+ fibroblasts have been found surrounding the areas of edema. They lack normal expression of several Cluster Differentiation (CD) proteins and express additional proteins that are not expressed in normal vocal cord fibroblasts. Furthermore, cigarette smoke was discovered to increase COX-2 and PGE2 expression in fibroblasts, which could indicate the role of cigarette
