Livedoid vasculopathy (LV) is an uncommon thrombotic dermal

atrophic scars, also known as Atrophie blanche.[5]

Livedoid vasculopathy has been linked to various conditions that can induce hypercoagulability, including neoplasms, autoimmune connective-tissue diseases, and inherited and acquired thrombophilias.[5]

The history, clinical findings, and histopathological analysis are combined to make the diagnosis.[5]

Prompt and suitable intervention mitigates discomfort and averts the formation of wounds and additional complications. In addition to general supportive measures, anticoagulants and antiplatelet medications can be considered the first-line treatments.[6]

Signs and symptoms

Recurrent focal non-inflammatory

pruritus with itchy papules and erythematous-violaceous, purpuric plaques. They quickly develop into bleeding vesicles, or bullae, which, when they burst, produce painful, small ulcers about 5 mm in diameter. These ulcers eventually combine to form painful, confluent, reticulate, and geometric ulcerations.[7]

Complications

Due to the tissue exposure, the primary acute complications are pain and secondary infection.

mononeuritis multiplex from vasa nervorum thrombosis, and cutaneous hemosiderosis in the lower limbs from erythrocytes oozing from the high-pressure regimen veins due to hemosiderin deposits in the skin are among the chronic complications associated with livedoid vasculopathy.[7]

Causes

Few things are known about the origins of dermal vessel thrombosis in livedoid vasculopathy, what sets off its initial episodes and relapses, and why it primarily affects the lower limbs.[4]

Risk factors

Livedoid vasculopathy has been linked to

systemic lupus erythematosus who also have antiphospholipid antibody syndrome are more vulnerable.[9]

Patients with hematological or solid organ cancers may also experience livedoid vasculopathy. Livedoid vasculopathy may deteriorate during pregnancy, particularly in the third trimester, though fetal compromise has not been documented. Still, a sizable fraction of cases are idiopathic.[9]

Genetics

Livedoid vasculopathy is caused by a number of inherited and acquired coagulation abnormalities, such as

prothrombin, and methylenetetrahydrofolate reductase (MTHFR).[6]

Mechanism

At this point, the pathomechanism of livedoid vasculopathy is not fully understood.

perfusion pressure, as well as a lower concentration of thrombolytic factors.[12][13]

Diagnosis

To diagnose livedoid vasculopathy and its causes, a thorough history, dermatological examination, and laboratory work-up are necessary.[9] A skin biopsy should be performed to confirm the diagnosis of livedoid vasculopathy when it is clinically suspected. The most suitable type of biopsy is a fusiform incisional biopsy that contains subcutaneous fat.[6]

Leukocytoclasia and a spare perivascular inflammatory infiltrate may be seen in the acute phase, but these results are not essential for the diagnosis.[14]

Following histopathological confirmation of the diagnosis, a more thorough evaluation of any potential underlying illnesses may be conducted. Naturally, the first steps in the assessment process should be a thorough history, a review of the systems, and a physical examination to look for any signs of underlying diseases. For every patient, thrombophilia laboratory testing is advised. More testing is necessary to determine whether thrombophilia is inherited or acquired, including looking into coagulating factors and their mutations.[6]

In the event that pertinent data suggestive of

paraproteinemia or solid organ cancers are suspected, tests for protein electrophoresisIg kappa and lambda chain levels, and immunofixation should be carried out. Again, testing for HIV and hepatitis should be done if there is a suspicion of an underlying infection.[6]

The initial step in the clinical work-up should be considering the differential diagnoses of additional common causes of atrophie blanche.

Doppler ultrasound findings, and the ankle-brachial index test. Cutaneous polyarteritis nodosa is another common differential diagnosis that causes similar cutaneous lesions on the legs. A proper skin biopsy can help differentiate vasculitis from livedoid vasculopathy.[6]

Treatment

Although there are numerous distinct treatment modalities for livedoid vasculopathy, no published, standardized, evidence-based therapeutic strategies exist.[5] The improvement of skin lesions, avoidance of relapses, and pain relief are the main goals of treatment for livedoid vasculopathy.[15] Since not every patient responds to a single therapy approach equally, it is necessary to evaluate or combine a number of treatment options.[6]

Treating pain related to ulcers with

hyperbaric oxygen, and routine wound debridement are examples of local therapies for livedoid vasculopathy.[4] Hyperbaric oxygen and compression therapy have been demonstrated to enhance fibrinolysis in addition to their respective roles in reducing edema and mitigating reperfusion injury.[16][17]

The most widely documented treatment for livedoid vasculopathy is oral anticoagulation, which directly addresses dermal vessel thrombosis.[15] The most widely used of these is rivaroxaban, which showed a significant reduction in pain after 12 weeks of therapy in an uncontrolled phase 2a trial.[18] Common substitutes are antiplatelet agents like aspirin and pentoxifylline.[4] Patients who are not responding to traditional therapies may benefit from the use of low-dose systemic thrombolytics.[19]

Epidemiology

According to estimates, the annual incidence of livedoid vasculopathy is 1:100,000, with women being affected at a ratio of 3:1. Patients may experience functional impairment for decades as the mean age of onset is in the 30s.[4]
