Livedo Reticularis
Livedo reticularis (pronunciation: li-VEE-do ret-ih-kyoo-LAIR-is) is a medical condition characterized by a mottled discoloration of the skin, typically in a netlike pattern.
Etymology
The term "livedo reticularis" is derived from the Latin "livedo," meaning "bluish discoloration of the skin," and "reticularis," meaning "net-like."
Definition
Livedo reticularis is a vascular condition that results in a lace-like purplish discoloration of the skin caused by dilation of the blood vessels. It can be a normal condition that is simply more visible when a person is exposed to cold or it can be an indication of an underlying disease.
Symptoms
The primary symptom of livedo reticularis is a distinct skin discoloration. The skin appears reddish-blue or purple in a pattern that resembles a lace or net. The discoloration is more pronounced in cold weather and less noticeable in warm conditions. Other symptoms may include skin ulcers or nodules, depending on the underlying cause.
Causes
Livedo reticularis can be caused by a variety of conditions, including rheumatoid arthritis, lupus, antiphospholipid syndrome, and pancreatitis. It can also be a side effect of certain medications.
Diagnosis
Diagnosis of livedo reticularis is primarily based on the characteristic appearance of the skin. Additional tests may be performed to identify any underlying conditions, such as blood tests, skin biopsy, or imaging studies.
Treatment
Treatment for livedo reticularis focuses on managing the underlying condition. This may involve medication to control symptoms, lifestyle changes, or in some cases, surgery.
