Livedo reticularis (LR) is a common finding and results from a physiological vasospastic response to cold or systemic disease, characterized by a pattern of cyanotic discoloration, or erythematous-cyanotic aspect. 37 Full PDFs related Current knowledge and key points: A livedo is a usually purplish-blue erythema, reticulated (small and complete meshes) or racemosa (large broken circular segments) which is related to a No further test or examination confirms idiopathic livedo reticularis, however, further investigations may be undertaken where an underlying cause is suspected such as skin biopsies, or blood tests for antibodies associated with antiphospholipid syndrome or systemic lupus erythematosus. Usefulness of the main diagnostic procedures is discussed. These symptoms are often more severe in cold weather.

A literature review. The livedo is a purplish erythema forming more or less regular mesh on the skin. Disease/Condition. Differential diagnoses The first step in evaluation of a livedo or a so-called livedoid eruption is to rule out the differential diagnoses (Table I). Avoid triggers (e.g., allergens and irritants such as metals, perfumes, or cigarette smoking) Differential diagnosis During the first few weeks after birth, when the lesions are not very reticulated, CMTC may look very similar to vascular lesions such as port-wine stains. Differential diagnosis includes ulceration and atrophie blanche arising in other diseases: Venous insufficiency with stasis dermatitis and leg ulceration; In other cases, underlying autoimmune diseases may be responsible for livedo reticularis. Livedo reticularis (LR) is a cutaneous physical sign characterized by transient or persistent, blotchy, reddish-blue to purple, net-like cyanotic pattern. LR may be physiologic, indicative of capillary vascular malformation, or associated with vasculitis or obstruction of flow.

Livedo reticularis is a lacy, purple skin discoloration that may be associated with a variety of conditions that cause circulatory abnormalities. Livedo reticularis is thought to be due to spasms of the blood vessels or a problem of the blood flow near the skin surface. The differential diagnosis of pernio includes other cold-induced syndromes such as Raynaud's syndrome, cold panniculitis, cold urticaria, livedo reticularis, acrocyanosis, and chilblain lupus. In contradistinction, atypical ischemic ulcerations of the lower extremity are often non-atherosclerotic in etiology, involve the proximal leg (thigh/buttocks), can evolve despite palpable distal pulses, and may coexist with other cutaneous aberrations (e.g. An evaluation for underlying disease is important, as livedo re-ticularis can be associated with the range of conditions listed above. Noninflammatory vessel wall abnormalities (nonpalpable purpura) Livedo reticularis, deep skin ulcers and nodules have also been described in patients with LCV but occur less often [5,6] and are a reflection of involvement of medium-sized arteries. + + FIGURE 75-1.

In Sneddon's syndrome, it is associated with widespread evidence of arterial disease involving cerebral, ocular, coronary and peripheral arteries. Atrophie blanchelike lesions are a fairly common end result of ulceration and are therefore not specific for livedoid vasculopathy. The venom contains melittin and phospholipase A2, which together disrupt the red cell membrane and cause hemolysis. However, identifying the cause of this is directed based on differential diagnoses. Pernio In addition, on both thighs a persistent, blotchy, purple, net-like pattern was noticed, suggestive for livedo reticularis (Figure 2). Netlike mottled vascular pattern secondary to amantadine in a young patient. It makes the skin look mottled in sort of a net pattern with clear borders. 252.

It is important to recall that livedoid vasculopathy can mimic an array of vascular conditions that go beyond a simple list of differential diagnoses. Differentiating Signs/Symptoms. 2005. pp. Differential diagnosis with APS could be difficult, because DIC is able to both mimic and complicate APS, especially in its catastrophic form while livedo reticularis (circular and continuous borders) is considered a benign condition and is more commonly encountered during clinical practice . It happens when the body's immune system attacks the blood vessel by mistake.

The differential diagnosis of chilblains is broad and depends on the stage of the disease at presentation as well as the appearance and location of the lesions. The physiological livedo reticularis usually appears in cold conditions, whereas the pathological and irregular livedo, which persists in warm temperatures, is often labeled as livedo racemosa. To rule out differential diagnoses (e.g., psoriasis) or in case of poor response to treatment. Livedoid vasculopathy is a chronic, painful, thrombo-occlusive cutaneous vasculopathy that involves the distal lower extremities and feet. Semiologically, it is fundamental to know the difference from livedo racemosa, characteristically showing poorly defined slim and open lesions.
