Case in brief
A patient developed livedo racemosa following an intra-articular injection of hyaluronic acid for osteoarthritis. The condition presented as a painful violaceous reticulated patch. Treatment with acetylsalicylic acid and topical fusidic acid led to resolution of the symptoms through a conservative approach.
What made this case unusual
This case highlights the occurrence of livedo racemosa, a vascular complication, after hyaluronic acid injection, which is less commonly reported compared to other complications.
Diagnostic / clinical pearl
Clinicians should be aware that livedo racemosa can occur after intra-articular hyaluronic acid injections, and conservative management with acetylsalicylic acid may be effective.
Why it matters
This case underscores the need for awareness of atypical vascular complications associated with hyaluronic acid injections and the potential for successful management with alternative therapies.
