Livedo reticularis is not linked directly to RA but can signify a dangerous condition
Livedo reticularis is a skin condition, and many believe that it has a tie to rheumatoid arthritis. However, research has been done that suggests the condition is not connected to rheumatoid arthritis, but rather an underlying condition that is quite serious.
The condition is often confusing to those who experience it, as it changes at different points of the year. It is considered to be a benign rash; however, in colder weather (usually winter) it will become significantly more prominent.
Livedo reticularis results from spasms within the blood vessels that result in purplish lines that are displayed in "net-like patterns."
Unfortunately, livedo reticularis can lead to other conditions that can become more serious, such as ulcers, painful nodules, and discoloration.
A particularly important reason to pay attention to livedo reticularis is that it may indicate that peripheral vascular disease or a clot within the blood vessels are present. Because it may be a sign of something more sinister under the surface, if you are experiencing livedo reticularis it is important to monitor the condition and speak with your doctor about it.
