A skin ailment called livedo reticularis results in a red, blue, purple, or brown skin discoloration that resembles a net or web. Decreased blood flow to the skin is the reason, and this can be brought on by a number of things, including exposure to cold temperatures, stress, or underlying illnesses. Depending on the cause and kind, livedo reticularis can be benign or dangerous, transient or permanent. We'll talk about livedo reticularis causes, symptoms, diagnosis, treatment, and prevention in this blog article.
Livedo reticularis can be classified into different types based on the cause and characteristics of the skin discoloration. Some of the common types are:
Physiologic livedo reticularis, also known as cutis marmorata, is the skin's typical, safe response to stress or low temperatures. It appears as a bluish or purple net-like pattern as the skin's blood vessels narrow and lessen blood flow. Usually affecting the trunk, arms, or legs, it goes away when the skin becomes more relaxed or heated.
Primary or idiopathic livedo reticularis: This kind of livedo reticularis is benign, sporadic, and has no recognized etiology. It is independent of both temperature and stress, and it endures even in the presence of relaxed or warmed skin. It often affects the lower legs and may be linked to other skin disorders such nodules or ulcers.
Livedo racemosa, also known as secondary livedo reticularis, is a severe and chronic type of livedo reticularis that is brought on by an underlying illness or condition that affects blood coagulation, blood cells, or blood vessels. Any area of the body may experience it, and its pattern is more erratic, fractured, or round. Systemic symptoms like fever, weight loss, or joint discomfort may be linked to it. The following are a few ailments that may result in secondary livedo reticularis:
Antiphospholipid syndrome (APS) is an autoimmune disease that results in irregular blood clotting, which obstructs or damages blood vessels. In addition to strokes, heart attacks, miscarriages, and blood clots in the legs or lungs, APS can result in livedo reticularis.
Sneddon’s syndrome: This is a rare disorder that causes livedo reticularis and strokes, due to inflammation and narrowing of the blood vessels in the brain and skin.
A uncommon condition called polyarteritis nodosa (PAN) affects the skin, kidneys, nerves, muscles, and other organs by inflaming and damaging the body's tiny and medium-sized arteries.
Cryoglobulinemia: This disorder is characterized by aberrant blood proteins known as cryoglobulins that aggregate and obstruct blood arteries in cold environments. Livedo reticularis, Raynaud's phenomenon, skin ulcers, joint discomfort, or renal issues can all be brought on by cryoglobulinemia.
Drug-induced livedo reticularis: This is an uncommon side effect of some drugs that can damage blood vessels or blood cells. Examples of these drugs include gemcitabine (used to treat cancer), amantadine (used to treat Parkinson's disease), and interferons (used to treat viral infections or malignancies). When a drug is withdrawn, livedo reticularis caused by drugs often goes away.
The primary sign of livedo reticularis is a net-like or web-like pattern of skin discoloration. Depending on the kind and source of livedo reticularis, this pattern can change in color, form, and location. When the skin is cold or under strain, the pattern could be more noticeable or prominent. To the touch, the skin might also seem sensitive or chilly. Other signs and symptoms of livedo reticularis include:
Pain, swelling, or warmth in the affected area, due to inflammation or infection of the skin or blood vessels.
Ulcers, nodules, or gangrene on the skin, due to poor blood supply or tissue damage.
Numbness, tingling, or weakness in the limbs, due to nerve damage or compression.
Headache, dizziness, or confusion, due to reduced blood flow or clotting in the brain.
Chest pain, shortness of breath, or palpitations, due to reduced blood flow or clotting in the heart or lungs.
Abdominal pain, nausea, or vomiting, due to reduced blood flow or clotting in the digestive organs.
Kidney problems, such as blood in the urine, protein in the urine, or reduced urine output, due to reduced blood flow or clotting in the kidneys.
Livedo reticularis can be diagnosed by a doctor who specializes in the diagnosis and treatment of skin conditions (dermatologist) or blood vessel disorders (vascular specialist). The diagnosis may involve:
Medical history and physical examination: The physician will inquire about the patient's current drugs or therapies, livedo reticularis or other relevant disorders in their family, and the symptoms, their beginning and course. In addition, the physician will inspect the skin to search for patterns, colors, and locations of discolorations indicative of livedo reticularis.
Blood testing: Antiphospholipid antibodies, cryoglobulins, complement levels, and other clotting diseases that may cause or be linked to livedo reticularis may be checked for by the doctor using blood tests.
Skin biopsy: The physician could remove a little piece of skin from the afflicted region and send it to a lab to be examined under a microscope. A skin sample can validate the livedo reticularis diagnosis and rule out other skin disorders including scleroderma, lupus, or vasculitis that may present with identical symptoms.
Imaging testing: To evaluate the anatomy and physiology of the blood vessels in the afflicted region and to identify any blockage, narrowing, or damage to the blood vessels, the physician may employ imaging tests like Doppler, angiography, or ultrasound.
The treatment of livedo reticularis depends on the type and cause of the condition, and the severity and extent of the symptoms. The main treatment options for livedo reticularis are:
Medication: The doctor may recommend antibiotics for infections, anti-inflammatory medicines for inflammation, or anticoagulants for clotting issues in order to address the underlying cause or disease of livedo reticularis. Moreover, medications can help reduce discomfort, swelling, and itching associated with livedo reticularis.
Therapy: In order to enhance lymphatic drainage and blood circulation in the afflicted area and to avoid or lessen the consequences of livedo reticularis, such as ulcers, gangrene, or infection, the patient may benefit from a variety of therapies, including physical therapy, massage therapy, or compression therapy. Additionally, therapy might enhance the skin's look and functionality.
Surgery: To restore blood flow and oxygen delivery to the skin and tissues, the doctor may advise surgery to remove or bypass the clogged or damaged blood arteries in the afflicted area. Surgery is another option for treating severe livedo reticularis skin damage, such as ulcers, nodules, or gangrene.
There is no way to prevent livedo reticularis, as it is a reaction of the skin to reduced blood flow, which can be due to various factors. However, there are some measures that can be taken to reduce the risk or severity of livedo reticularis, such as:
Avoiding or limiting exposure to cold temperatures or stress, which can trigger or worsen physiologic livedo reticularis, by wearing warm clothing, gloves, and socks, and practicing relaxation techniques.
By leading a healthy lifestyle that includes eating a well-balanced and nutrient-rich diet, getting regular exercise, abstaining from tobacco use, and limiting alcohol intake, one may enhance the health and performance of their immune systems, blood vessels, and prevent inflammation and infection.
Visiting a physician who specializes in the diagnosis and treatment of skin conditions or blood vessel disorders, having regular check-ups and screenings for any signs of livedo reticularis, or the underlying conditions that may cause or be associated with it, such as antiphospholipid syndrome, Sneddon's syndrome, polyarteritis nodosa, or cryoglobulinemia, and undergoing blood tests or imaging tests as recommended.
