Primary Livedo Reticularis

Primary or idiopathic livedo reticularis is a change in the coloring of the skin that forms a net or mesh-like pattern, of a reddish or violet tone, without any underlying cause that can be identified. It is related to the way blood circulates in the small vessels of the skin.

How it presents: the reticulated pattern is usually more noticeable on the legs and arms, and it often becomes more pronounced with the cold and then fades with warmth.

Key feature: in its primary form it is not associated with another disease and tends to be benign, though it is advisable to confirm this.

Which specialist evaluates it? The internist can carry out a comprehensive evaluation and the vascular surgeon can study the circulation. If the pattern is persistent or is accompanied by other symptoms, the prudent thing is to have it checked by a professional.
