Skin often reflects internal health, and one example is Livedo Reticularis (LR), a vascular disorder appearing as a purplish, lace-like discoloration. While sometimes harmless, it can also signal serious conditions.

What is Livedo Reticularis?
LR shows as a “mottled, web-like pattern of reddish-blue or purple discoloration” on the legs, arms, or trunk. It occurs when blood flow in small vessels slows or pools, often worsening in cold weather and fading with warmth.

Types

Physiological (Primary): A benign, temporary reaction to cold, common in children and fair-skinned adults.

Pathological (Secondary): Linked to autoimmune diseases, vascular problems, or clotting disorders, requiring medical care.

Causes & Symptoms
Triggers include cold exposure, lupus, vasculitis, blood clotting disorders, or certain medications. Symptoms may involve “coldness or numbness,” pain, ulcers, or even neurological issues.

Diagnosis & Treatment
Doctors use exams, blood tests, or imaging. Primary LR needs no treatment beyond warmth, while secondary LR may require anticoagulants, steroids, or lifestyle changes. Persistent discoloration or added symptoms should prompt medical consultation.
