Livedo reticularis

Livedo reticularis is a medical condition characterized by a mottled discoloration of the skin, typically in a netlike pattern. It can be caused by a variety of conditions, including rheumatologic diseases, vascular diseases, and autoimmune diseases.

Symptoms[edit | edit source]

The primary symptom of livedo reticularis is a reddish-blue, netlike discoloration of the skin. This discoloration is most commonly seen on the legs, but can also appear on the arms, trunk, and other areas of the body. The discoloration may become more pronounced when the skin is exposed to cold temperatures.

Causes[edit | edit source]

Livedo reticularis can be caused by a variety of conditions, including:

Rheumatologic diseases such as rheumatoid arthritis and lupus
Vascular diseases such as vasculitis and Raynaud's disease
Autoimmune diseases such as antiphospholipid syndrome
Certain medications, including amantadine and minocycline

In some cases, livedo reticularis may be idiopathic, meaning its cause is unknown.

Diagnosis[edit | edit source]

Diagnosis of livedo reticularis typically involves a physical examination and a review of the patient's medical history. In some cases, additional tests may be needed to determine the underlying cause of the condition. These tests may include blood tests, skin biopsies, and imaging studies.

Treatment[edit | edit source]

Treatment for livedo reticularis depends on the underlying cause of the condition. In some cases, treating the underlying condition can help to reduce the symptoms of livedo reticularis. In other cases, treatment may involve medications to improve blood flow, such as aspirin or pentoxifylline.
