Livedo racemosa secondary to hyaluronic acid injection

Iatrogenic vascular occlusion secondary to filler injection, such as with hyaluronic acid, is a known but rare, entity. It typically occurs in the setting of facial cosmetic procedures but has also been described in the setting of osteoarthritis. We present a patient with ankle osteoarthritis who developed an asymmetric, reticular, livedoid eruption after intraarticular injection with hyaluronic acid. She was diagnosed with livedo racemosa secondary to vascular occlusion and placed on low molecular weight heparin. Later, a transition to low-dose daily aspirin maintained the improvement.
