Background: Coagulation disorders contribute to the development of livedoid vasculopathy (LV). Elevated plasma levels of lipoprotein(a) [Lp(a)] are an independent risk factor for the development of cardiovascular disease and associated with hypercoagulable states. Increased serum Lp(a) levels have been reported in patients with LV and may have an important role in the pathogenesis of LV. Read More
The most of the emergency in dermatology comprise a variety of entities that most are benign in course. However the vasculopathies and vasculitis are not common,but they could represent the 1,9% and 4,4% according to some studies of emergency dermatology department. They become an important diseases which have to identified early to established an appropiate managment and treatment. Read More

Nicolau syndrome is a rare form of iatrogenic cutaneous necrosis which affects injection sites. Although classically associated with intramuscular injections, it may develop after subcutaneous or other routes of parenteral drug administration. Clinically, it manifests as necrotic ulcers that often develop in a background of erythematous and livedoid reticular patches. Read More
We describe three patients who presented with a striking erythematous non-blanching annular eruption and features of lymphocytic thrombophilic arteritis (LTA), with a prominent lymphocytic vasculitis involving deep dermal vessels. Lymphocytic inflammation was also evident in the superficial vessels and one patient had small superficial ulcers over the ankle area resembling livedoid vasculopathy (LV). Multiple biopsies demonstrated a persistent absence of neutrophils in the infiltrate consistent with a lymphocytic process. Read More
Livedoid vasculopathy (LV) is a thrombotic skin disease characterised by recurrent painful ulcerations and irreversible scar formation on the lower legs, which is caused by occlusion of the cutaneous microcirculation. Edoxaban is one of new oral anticoagulants. It directly inhibits factor Xa in the coagulation pathway and prevents thrombus formation. Read More

Livedoid vasculopathy (atrophie blanche) is a form of thrombotic vasculopathy. It is characterized by small ulcers that become crusted, and heal after several months to produce white atrophic scars. The most commonly affected sites are the lower legs, in particular the dorsum of the feet and ankles. Read More
Background: Livedoid vasculopathy (LV) is a painful ulcerative condition involving white atrophy and livedo; a histopathologic feature seen is occlusive dermal vasculopathy. This may be associated with coagulation disorders such as hyperhomocysteinaemia (HHC).
Patients And Methods: We report the case of a 52-year-old woman presenting LV in which an abnormal scan image led us to diagnose coeliac disease. Read More
Background: Livedoid vasculopathy and calciphylaxis are rare skin disorders. Large cohorts of patients have been missing so far for detailed analysis.
Patients And Methods: Data from diagnosis-related groups (DRGs) of hospitalized cases of livedoid vasculopathy (ntotal = 1357) and calciphylaxis (ntotal = 699) were analysed for the years 2008-2013 concerning sex, age and frequency of diagnosis. Read More
Objective: Chronic wounds are a major cause of morbidity and mortality. Approximately 20% to 23% of nonhealing wounds that are refractory to vascular intervention have other causes, including vasculitis, pyoderma gangrenosum, and other autoimmune diseases. The purpose of this article was to review the literature across medical and surgical specialties with regard to refractory chronic wounds associated with vasculitis and autoimmune diseases and to delineate clinical outcomes of these wounds in response to vascular and other interventions.

Aim: Thrombosis and inflammation play an important role in pathophysiology of livedoid vasculopathy (LV). Plasminogen activator inhibitor-1 (PAI-1) is the main physiological inhibitor of fibrinolysis and is a pivotal modulator in a broad range of biological processes.
Method: The study specimens were retrospectively selected from archives of pathology department. Read More
A 71-year-old man presented with a high fever, polyarthralgia, petechiae and palpable purpura accompanied by livedoid change on his legs and feet. Histopathological findings of the purpura revealed perivascular infiltration of neutrophils, mononuclear cells, and nuclear debris, and extravasation of red cells mainly in the upper dermis: all signs consistent with leukocytoclastic vasculitis. Small vessel thrombi, which are characteristic features of septic vasculopathy, were also observed. Read More
We present a rare association of idiopathic livedoid vasculopathy (LV) with peripheral sensory neuropathy successfully treated with intravenous immunoglobulin and warfarin and, after its failure, with rituximab. Although LV aetiology remains incompletely understood, the excellent clinical response observed in our patient suggests that B cells may be key players in its pathogenesis. Read More
Livedoid vasculopathy (LV) is a chronic disease with recurrent reticularis and ulcers, mainly affecting the feet and lower legs. The pathogenesis of LV has not been yet thoroughly understood, but thrombosis is thought to play a major role because fibrin deposition within both the wall and lumen of affected vessels is pathologically detected. A 68-year-old woman first presented to our hospital in 2004 with a 6-year history of a reticular rash and ulceration on the lower legs. Read More

Anticoagulants are the cornerstone of treatment of venous thromboembolism associated with various medical conditions and surgical procedures. They act on different steps of the coagulation pathway and are broadly categorized into heparins, vitamin K antagonists, and inhibitors of thrombin and factor Xa. The classification is evolving as newer and better oral and parenteral anticoagulants are being added. Read More
Livedoid vasculopathy is a rare cutaneous disease manifesting as recurrent ulcers on the lower extremities. The ulceration results in atrophic, porcelain white scars termed as atrophie blanche. The pathogenesis is yet to be understood with the main mechanism being hypercoagulability and inflammation playing a secondary role. Read More
Both inherited and acquired hypercoagulable states can present with nonspecific clinical manifestations, such as petechiae, purpura, livedo reticularis, and ulcerations. A good history and physical examination are crucial to diagnoses of these conditions. Inherited conditions tend to present either in neonatal period or later in life, while acquired conditions typically occur later in life. Read More
Livedoid vasculopathy is a chronic and painful skin disease that progresses to ulceration. Due to its uncertain pathogenesis, there is no single effective treatment for this condition, and current therapeutic options are based on isolated case reports, or on case series. We report a case of a female patient with livedoid vasculopathy, which achieved excellent healing of lower limb ulcers after using an anti-TNF agent. Read More
Background: Livedoid vasculopathy is a thrombotic skin disease characterised by recurrent occlusion of the cutaneous microcirculation in lower extremities, which results in skin infarctions with painful ulcerations and irreversible scar formation. Rivaroxaban is a direct factor Xa inhibitor that prevents thrombus formation. We investigated whether rivaroxaban is effective for the treatment of livedoid vasculopathy. Read More

Livedoid vasculopathy is a chronic disorder characterised by recurrent reticulated purpura on lower extremities, associated with painful purpuric or necrotic macules and ulcerations. Current knowledge indicates LV to be a thrombo-occlusive vasculopathy of cutaneous blood vessels; exact pathogenesis is yet to be understood. Elevated levels of lipoprotein(a) have been found in LV patients. Read More
Vascular acrosyndromes are associated with vasomotor disorders. They may be paroxysmal, like Raynaud's phenomenon, whitening of the fingers on exposure to cold, or erythromelalgia, a painful form of erythema induced by exposure to heat. Others are permanent or semi-permanent, such as acrocyanosis, chilblains, spontaneous haematoma of the fingers, acrocholose and digital ischaemia or necrosis. Read More

The most recent pediatric vasculitis classifications (EULAR/PRINTO/PRES) have proposed the use of an integration of clinical signs and symptoms, laboratory data, imaging and pathologic data. Pediatric vasculitis represent a peculiar clinical-diagnostic model, compared to the corresponding adult pathology chapter, and in particular, dermatopathologic aspects of these diseases identify more specific issues, made contingent by crucial variables such as duration of vasculitis lesion, site of the biopsy, proper biopsy depth, and possibility to correlate histopathological findings with immunopathological results. Possible additional diagnostic difficulties may arise from the fact that, in children, the same systemic disease, such as lupus erythematosus, may present with different clinical manifestations, with histopathological features of a precise type of vasculitis specific for that type of clinical manifestation.
