Should livedo reticularis be indicative of a a condition called Lupus or is it common after sclerotherapy as the blood is re-routing?
Although livedo reticularis is associated with collagen problems as well as lupus and periarteritis nodosa, it frequently occurs in normal people. It is often associated with cold exposure and is due to spasm of the small arterioles in the skin with resultant dilation of the capillaries. Since sclerotherapy does cause constriction of the small vessels, it would seem that LR could occur following treatment. More likely, however, what you may be seeing is matting of the neighboring venules.
