Abstract
Cholesterol crystal (CC) embolism is a disease in which CCs from atherosclerotic lesions embolize peripheral arteries, causing organ dysfunction. In this case, a patient with spontaneously ruptured aortic plaques (SRAPs) identified by non-obstructive general angioscopy (NOGA) may have developed a CC embolism. This is the first report of a CC embolism in a patient with SRAPs identified using NOGA, which further supports the previously speculated pathogenesis of CC embolism due to SRAPs.

Abstract
Cholesterol embolization syndrome is an increasing but underestimated problem after endovascular intervention or after the start of thrombolytic therapies. Embolies from the aortic wall involves abdominal organs and the skin of the lower extremities or buttocks. In our case a progressive ulceration and necroses occurs spontaneously. Endovascular treatment of the lower extremities was successful for a short period. Due to the progression of necrosis, both legs were amputated. Biopsies were taken from the skin were initially no directions to the diagnosis of Cholesterol embolization syndrome. After a second elliptical excision biopsy the diagnosis of cholesterol embolization syndrome was confirmed. Because the rapid progression of skin necroses despite the treatment of prednisone, patient died due to sepsis and renal failure. This case shows when arterial revascularization is performed and progression in skin necrosis occurs despite optimal arterial vascular status the diagnosis CES should be considered and treated in an early state of disease.

Abstract
Introduction Cholesterol crystal embolism is a rare microembolic disease caused by cholesterol crystals that can present with various symptoms after vascular surgery, catheterization, or anticoagulation therapy. We report a case of penile ulceration caused by cholesterol crystal embolism. Case presentation A 72-year-old man undergoing maintenance dialysis for end-stage renal failure presented with penile pain and a black glans ulcer. Despite low-density lipoprotein apheresis, he was referred to our hospital because of lack of improvement. Based on his medical history and clinical presentation, including artificial vascular replacement and right toe amputation, cholesterol crystal embolism was suspected and partial penectomy was performed, thus confirming the diagnosis. Penile pain resolved after surgery, and he was discharged on Day 10. Unfortunately, he died after small bowel perforation developed 2 months after surgery. Conclusion Penile ulcers caused by cholesterol crystal embolism may indicate the severity and progression of disease and typically require surgical intervention.

Abstract
BACKGROUND AND AIMS Cholesterol crystal embolism-related cerebral infarction (CCE-CI) is frequently misdiagnosed due to the lack of specific symptoms. To aid in differential diagnosis, this study comprehensively characterized the magnetic resonance imaging (MRI) and clinical manifestations of CCE-CI and compared these features to those of atherothrombotic cerebral infarction (ACI). METHODS This single-center, retrospective, observational study was conducted at Kitasato University Hospital, Kanagawa, Japan. We identified 37 clinically or histopathologically confirmed CCE-CI cases and 110 ACI cases treated from January 2006 to May 2020. Groups were compared for mean age, sex ratio, clinical presentations, imaging manifestations, precipitating factors, comorbid conditions, medications, and smoking history. RESULTS Of 37 eligible patients with CCE-CI, 10 (27.0%) received brain MRI, of which 8 (21.6%) exhibited high-intensity signals indicative of brain lesions on diffusion-weighted imaging (DWI). However, two patients with DWI lesions exhibited no detectable neurological abnormalities. Patients with CCE-CI frequently demonstrated bilateral DWI lesions involving the bilateral anterior and posterior circulation, a pattern absent in ACI (50% vs. 0%, p < 0.001). Compared to patients with ACI, CCE-CI patients also demonstrated significantly lower estimated glomerular filtration rate (p < 0.001) as well as more frequent eosinophilia (p = 0.006), atherosclerotic plaques ≥4-mm thick in the ascending aorta or proximal arch (p = 0.001), and aortic aneurysm (p < 0.001). CONCLUSIONS Patients with CCE-CI develop multiple DWI lesions across several vascular territories, even in the absence of neurological symptoms. Comorbid aortic aneurysm may increase CCE-CI risk. These findings could help in the differential diagnosis of CCE-CI.

Abstract
Cholesterol crystals (CCs) were first discovered in atherosclerotic plaque tissue in the early 1900 and have since been observed and implicated in many diseases and conditions, including myocardial infarction, abdominal aortic aneurism, kidney disease, ocular diseases, and even central nervous system anomalies. Despite the widespread involvement of CCs in many pathologies, the mechanisms involved in their formation and their role in various diseases are still not fully understood. Current knowledge concerning the formation of CCs, as well as the molecular pathways activated upon cellular exposure to CCs, will be explored in this review. As CC formation is tightly associated with lipid metabolism, the role of cellular lipid homeostasis in the formation of CCs is highlighted, including the role of lysosomes. In addition, cellular pathways and processes known to be affected by CCs are described. In particular, CC-induced activation of the inflammasome and production of reactive oxygen species, along with the role of CCs in complement-mediated inflammation is discussed. Moreover, the clinical manifestation of embolized CCs is described with a focus on renal and skin diseases associated with CC embolism. Lastly, potential therapeutic measures that target either the formation of CCs or their impact on different cell types and tissues are highlighted.

Abstract
Cholesterol crystal embolism is a systemic pathology associated with diffuse atherosclerosis. Pathophysiology corresponds to tissue necro-inflammation secondary to arteriolar occlusion associated with microembolism from atherosclerotic plaques of large diameter arteries. The clinical presentation is heterogeneous and polymorphic. Multiple organs may be the targets, but preferential damage is skin, kidneys and digestive system. It is a serious pathology, underdiagnosed, with a poor prognosis. The risk factors for developing the disease remain the same risk factors as atheroma. The factors favouring migration of microembolism remain mainly vascular interventional procedures; easy to diagnose, they oppose spontaneous embolic migrations or secondary to the introduction of antithrombotic treatment, whose diagnosis is more difficult and the prognosis more severe. The diagnosis of the disease remains mostly a diagnosis of elimination and often refers to a bundle of clinical, biological, morphological and histologic arguments. The treatment is poorly codified and the subject of few publications. It will favour both symptomatic treatment (and mainly that of pain) and complications (high blood pressure, renal insufficiency). The aetiological support remains less consensual. The treatment of atherosclerotic plaques consists, of course, in the correction of classical cardiovascular risk factors, the introduction of a statin. It will be discussed in the implementation of surgery or angioplasty to exclude potentially responsible atherosclerotic lesions. Eviction of antithrombotic therapy should be considered in terms of the benefit-risk balance, but often in favour of maintaining it. Finally, other treatments may be proposed in a case-by-case basis, such as oral or intravenous corticosteroid therapy, colchicine or LDL aphaeresis.

Abstract
Cholesterol-embolization syndrome (CES) is a multisystemic disease with various clinical manifestations. CES is caused by embolization of cholesterol crystals (CCs) from atherosclerotic plaques located in the major arteries, and is induced mostly iatrogenically by interventional and surgical procedures; however, it may also occur spontaneously. Embolized CCs lead to both ischemic and inflammatory damage to the target organ. Therefore, anti-inflammatory agents, such as corticosteroids and cyclophosphamide, have been investigated as treatment for CES in several studies, with conflicting results. Recent research has revealed that CES is actually a kind of autoinflammatory disease in which inflammasome pathways, such as NLRP3 and IL1, are induced by CCs. These recent findings may have clinical implications such that colchicine and IL1 inhibitors, namely canakinumab, may be beneficial in the early stages of CES.

Abstract
BACKGROUND Atheroembolic renal disease (AERD) is caused by occlusion of the small renal arteries from embolized cholesterol crystals arising from ulcerated atherosclerotic plaques. This usually manifests as isolated renal disease or involvement from systemic atheroembolic disease. Here we report a case of AERD that responded well to steroid therapy. CASE SUMMARY A 62-year-old woman with a history of hypertension and stage IIIa chronic kidney disease was referred for rapidly worsening renal function over a 4-mo period. She complained of swollen legs, dyspnea on exertion, and two episodes of epistaxis about a month prior to admission. She reported no history of invasive vascular procedures, use of radio contrast agents, or treatment with anticoagulants or thrombolytic agents. Urinalysis showed a few red blood cells and granular casts. Serology was positive for cytoplasmic antineutrophil cytoplasmic antibodies (c-ANCA). Non-contrast-enhanced computed tomography of the chest, abdomen, and pelvis showed diffuse atherosclerotic changes in the aortic arch. Thus, c-ANCA-associated vasculitis was suspected, and the patient was started on pulse intravenous methylprednisolone. Her renal biopsy showed evidence of AERD. She was discharged with oral prednisone, and her renal function continued to improve during the initial follow-up. CONCLUSION In cases of non-vasculitis-associated ANCA, a high degree of clinical suspicion is required to pursue the diagnosis of spontaneous AERD in patients with clinical or radiological evidence of atherosclerotic burden. Although no specific treatment is available, the potential role of statins and steroids requires exploration.

Abstract
BACKGROUND Cholesterol crystal embolism (CCE) causes renal damage, and there is an extremely high risk of end-stage renal disease. However, the time course of CCE-related renal deterioration varies and little is known about the subsequent risk of dialysis among patients with biopsy-proven CCE. METHODS We performed a retrospective cohort study of 38 Japanese patients in whom a histological diagnosis of CCE was made from September 1992 to July 2005. Competing risk regression analysis was used to investigate the association between declining renal function ( ≥ 1.5 elevation of serum creatinine within 26 weeks after CCE) or its subtypes (acute [ < 1 week after CCE], subacute [1 to < 6 weeks], and chronic [6 to < 26 weeks]) and the risk of dialysis, with adjustment for age, baseline serum creatinine, and the precipitating event (iatrogenic or spontaneous). RESULTS During a median follow-up period of 25.9 weeks, 14 patients (35.9%) started dialysis. Multivariable analysis showed that patients with declining renal function had a higher risk of commencing dialysis than those without declining function (subdistribution hazard ratio [SHR] 9.47; 95% confidence interval [CI] 1.34-66.8). Patients with different renal presentations had a similarly increased risk of commencing dialysis, with the risk being significantly higher for the subacute and chronic patterns of declining renal function (adjusted SHR [95% CI] for acute, subacute, and chronic declining renal function[vs. no decline]: 7.36 [0.85-63.6], 11.9 [1.36-101], and 10.7 [1.49-77.0], respectively). CONCLUSION Declining renal function after CCE, even later than 6 weeks, was significantly associated with the subsequent risk of dialysis.

Abstract
An 80-year-old man presented at our hospital with renal failure. He had been treated with edoxaban, an oral direct factor Xa inhibitor, for deep vein thrombosis for 10 months prior to admission. Although the pulses in his bilateral pedal arteries were palpable, cyanosis was present in the bilateral toes. Laboratory data indicated azotemia and eosinophilia. A skin biopsy confirmed a diagnosis of cholesterol crystal embolism (CCE). Because no invasive vascular procedure was performed, we assumed that CCE was related to edoxaban. To the best of our knowledge, this is the first case report suggesting CCE induced by an Xa inhibitor.

Abstract
Renal disease caused by cholesterol crystal embolism (CCE) occurs when cholesterol crystals become lodged in small renal arteries after small pieces of atheromatous plaques break off from the aorta or renal arteries and shower the downstream vascular bed. CCE is a multisystemic disease but kidneys are particularly vulnerable to atheroembolic disease, which can cause an acute, subacute, or chronic decline in renal function. This life-threatening disease may be underdiagnosed and overlooked as a cause of chronic kidney disease (CKD) among patients with advanced atherosclerosis. CCE can result from vascular surgery, angiography, or administration of anticoagulants. Atheroembolic renal disease has various clinical features that resemble those found in other kidney disorders and systemic diseases. It is commonly misdiagnosed in clinic, but confirmed by characteristic renal biopsy findings. Therapeutic options are limited, and prognosis is considered to be poor. Expanding knowledge of atheroembolic renal disease due to CCE opens perspectives for recognition, diagnosis, and treatment of this cause of progressive renal insufficiency.

Abstract
Cholesterol crystal embolic (CCE) syndrome is often a clinically challenging condition that has a poor prognostic implication. It is a result of plaque rupture with release of cholesterol crystals into the circulation that embolize into various tissue organs. Plaque rupture seems to be triggered by an expanding necrotic core during cholesterol crystallization forming sharp tipped crystals that perforate and tear the fibrous cap. Embolizing cholesterol crystals then initiate both local and systemic inflammation that eventually lead to vascular fibrosis and obstruction causing symptoms that can mimic other vasculitic conditions. In fact, animal studies have demonstrated that cholesterol crystals can trigger an inflammatory response via NLRP3 inflammasome similar to that seen with gout. The diagnosis of CCE syndrome often requires a high suspicion of the condition. Serum inflammation biomarkers including elevated sedimentation rate, abnormal renal function tests and eosinophilia are useful but non-specific. Common target organ involvement includes the skin, kidney, and brain. Various testing including fundoscopic eye examination and other non-invasive procedures such as trans-esophageal echocardiography and magnetic resonance imaging may be helpful in identifying the embolic source. Treatment includes aspirin and clopidogrel, high dose statin and possibly steroids. In rare cases, mechanical intervention using covered stents may help isolate the ruptured plaque. Anticoagulation with warfarin is not recommended and might even be harmful. Overall, CCE syndrome is usually a harbinger of extensive and unstable atherosclerotic disease that is often associated with acute cardiovascular events.

Abstract
Atheromatous embolization is a multisystem disease complicating advanced atherosclerosis. It occurs most often as a complication of angiography, an endovascular procedure or cardiovascular surgery. Atheromatous embolization can present in a subtle manner where it is often under-recognized, or with catastrophic results including myocardial infarction, strake or acute renal failure. It may mimic other disease processes and often goes underdiagnosed and undertreated. A high clinical suspicion is the key to diagnosis. Atheromatous embolization results in significant morbidity and mortality; therefore, early recognition followed by aggressive management may help to prevent end-organ damage and improve overall clinical outcomes. Management strategies should include risk factor modification, prevention of further insults by discontinuing or avoiding predisposing factors, supportive treatment and interventional or surgical approaches to remove the atheroembolic source. Atheromatous embolization is expected to increase as our population ages and the epidemics of diabetes mellitus and obesity increase.

Abstract
Up to a third of strokes are rendered cryptogenic or of undetermined etiology. This number is specifically higher in younger patients. At times, inadequate diagnostic workups, multiple causes, or an under-recognized etiology contributes to this statistic. Embolic stroke of undetermined source, a new clinical entity particularly refers to patients with embolic stroke for whom the etiology of embolism remains unidentified despite through investigations ruling out established cardiac and vascular sources. In this article, we review current classification and discuss important clinical considerations in these patients; highlighting cardiac arrhythmias and structural abnormalities, patent foramen ovale, paradoxical sources, and potentially under-recognized, vascular, inflammatory, autoimmune, and hematologic sources in relation to clinical practice.

Abstract
The age-adjusted prevalence of peripheral arterial disease in the US population has been estimated to approach 12%. The clinical consequences of occlusive peripheral arterial disease include pain on walking (claudication), pain at rest, and loss of tissue integrity in the distal limbs; the latter may ultimately lead to amputation of a portion of the lower extremity. Surgical bypass techniques and percutaneous catheter-based interventions may successfully reperfuse the limbs of certain patients with peripheral arterial disease. In many patients, however, the anatomic extent and distribution of arterial occlusion is too severe to permit relief of pain and healing of ischemic ulcers. No effective medical therapy is available for the treatment of such patients, for many of whom amputation represents the only hope for alleviation of symptoms. The ultimate failure of medical treatment and procedural revascularization in significant numbers of patients has led to attempts to develop alternative therapies for ischemic disease. These strategies include administration of angiogenic cytokines, either as recombinant protein or as gene therapy, and more recently, to investigations of stem/progenitor cell therapy. The purpose of this review is to provide an outline of the preclinical basis for angiogenic and stem cell therapies, review the clinical research that has been done, summarize the lessons learned, identify gaps in knowledge, and suggest a course toward successfully addressing an unmet medical need in a large and growing patient population.

Abstract
Cholesterol crystal embolization (CCE) is characterized by tissue ischemia secondary to occlusion of small arteries. It may occur spontaneously but more often follows radiological interventional procedures or vascular surgery. This systemic disease affects multiple organs, including skin, kidney, brain, eye, and gastrointestinal tract. We reported a Japanese male CCE patient with cutaneous manifestations of livedo reticularis, diarrhea, clouding of consciousness, and acute renal failure. Histopathological examination demonstrated multiple biconvex clefts in a vessel of the subcutis. Corticosteroid administration improved his consciousness, diarrhea and skin lesions. Awareness of the skin manifestations of CCE is essential for dermatologists to make an early diagnosis and prescribe appropriate treatment.

Abstract
Cholesterol embolisation syndrome (CES) is a rare but serious disease with high mortality caused by the formation of an embolus made up of cholesterol crystals from atherosclerotic plaques. Its clinical presentation is usually initially insidious and it often remains unrecognised because of its non-specific clinical presentation, which can cause delays in treatment and high mortality. The most common physical symptoms are cutaneous. We present a lethal case of CES to increase the awareness about this serious condition.

Abstract
Cholesterol emboli syndrome is a relatively rare, but potentially devastating, manifestation of atherosclerotic disease. Cholesterol emboli syndrome is characterized by waves of arterio-arterial embolization of cholesterol crystals and atheroma debris from atherosclerotic plaques in the aorta or its large branches to small or medium caliber arteries (100-200 μm in diameter) that frequently occur after invasive arterial procedures. End-organ damage is due to mechanical occlusion and inflammatory response in the destination arteries. Clinical manifestations may include renal failure, blue toe syndrome, global neurologic deficits and a variety of gastrointestinal, ocular and constitutional signs and symptoms. There is no specific therapy for cholesterol emboli syndrome. Supportive measures include modifications of risk factors, use of statins and antiplatelet agents, avoidance of anticoagulation and thrombolytic agents, and utilization of surgical and endovascular techniques to exclude sources of cholesterol emboli.

Abstract
Connective tissue disorders (CTD), which are often also termed collagen vascular diseases, include a number of related inflammatory conditions. Some of these diseases include rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis (scleroderma), localized scleroderma (morphea variants localized to the skin), Sjogren's syndrome, dermatomyositis, polymyositis, and mixed connective tissue disease. In addition to the systemic manifestations of these diseases, there are a number of cutaneous features that make these conditions recognizable on physical exam. Lower extremity ulcers and digital ulcers are an infrequent but disabling complication of long-standing connective tissue disease. The exact frequency with which these ulcers occur is not known, and the cause of the ulcerations is often multifactorial. Moreover, a challenging component of CTD ulcerations is that there are still no established guidelines for their diagnosis and treatment. The morbidity associated with these ulcerations and their underlying conditions is very substantial. Indeed, these less common but intractable ulcers represent a major medical and economic problem for patients, physicians and nurses, and even well organized multidisciplinary wound healing centers.

Abstract
Cholesterol crystal embolization (CCE) is one of the many complications of atherosclerosis. CCE is usually an iatrogenic event occurring either after vascular surgery, usually aortic surgery, or invasive angiographic investigations or in the course of anticoagulant or thrombolytic therapy. More rarely, it occurs after trauma or even in the absence of any inciting cause. CCE may manifest with single or multiorgan involvement. Skin involvement is usually seen in the context of a systemic disease, especially affecting the lower extremities and lower trunk. We report on a rare case of isolated spontaneous focal cutaneous involvement of the upper limb, with peculiar mesenchymal and reactive histological changes. A 65-year-old man with a clinical history of atherosclerosis was admitted complaining of a nonhealing painful skin ulceration on his left elbow for 5-month duration. A skin biopsy was taken, and histopathological examination documented an intrarteriolar cholesterol embolus in the dermis along with a peculiar adjacent bizarre fibroblastic reaction, of the type usually seen in atypical decubital fibroplasia of debilitated patients. The ulceration was surgically excised, and the wound was sutured and repaired. At 18-month follow-up, the patient has no evidence of local disease.

Abstract
Skin ulceration is a major source of morbidity and is often difficult to manage. Ulcers caused by an inflammatory cause or microvascular occlusion are particularly challenging in terms of diagnosis and treatment. The management of such ulcers requires careful assessment of associated systemic conditions and a thorough analysis of the ulcer's clinical and histologic findings. In this article, the authors discuss several examples of inflammatory ulcers and the approach to the diagnosis and treatment of these ulcers.

Abstract
Atheroembolic renal disease develops when atheromatous aortic plaques rupture, releasing cholesterol crystals into the small renal arteries. Embolisation often affects other organs, such as the skin, gastrointestinal system, and brain. Although the disease can develop spontaneously, it usually develops after vascular surgery, catheterisation, or anticoagulation. The systemic nature of atheroembolism makes diagnosis difficult. The classic triad of a precipitating event, acute or subacute renal failure, and skin lesions, are strongly suggestive of the disorder. Eosinophilia further supports the diagnosis, usually confirmed by biopsy of an affected organ or by the fundoscopic finding of cholesterol crystals in the retinal circulation. Renal and patient prognosis are poor. Treatment is mostly preventive, based on avoidance of further precipitating factors, and symptomatic, aimed to the optimum treatment of hypertension and cardiac and renal failure. Statins, which stabilise atherosclerotic plaques, should be offered to all patients. Steroids might have a role in acute or subacute progressive forms with systemic inflammation.

Abstract
Cutaneous ulcers are a difficult problem. A multidisciplinary approach is often adapted in caring for patients with nonhealing wounds. Internists, surgeons, dermatologists, and nurses must work together to provide a patient with the most comprehensive care possible. Dermatologists are consulted for a number of reasons, particularly if the ulcers are secondary to an inflammatory process. In this discussion, we describe a basic and useful approach to the diagnosis and management of inflammatory ulcers. The spectrum of these conditions is wide, ranging from vasculitis, to pyoderma gangrenosum, to ulcers resulting from the antiphospholipid syndrome and cryoprecipitates. The present authors will emphasize that the approach needs to be all-encompassing, and not focused on the ulceration alone. Certain clues are critical to diagnosis. The management, whereas often difficult, can be very rewarding.

Abstract
Cutaneous pseudovasculitis represents a heterogeneous collection of disorders that are capable of simulating cutaneous vasculitis and can be broadly classified into diseases that produce hemorrhage (petechiae, purpura, and ecchymoses) or vessel occlusion with resultant livedo, cyanosis, ulcers, digital necrosis, and/or gangrene. Overlap is not uncommon, but if present, one mechanism dominates. Hemorrhagic pseudovasculitis is due to vessel wall dysfunction (incompetence), which can be related to diverse factors that include vessel wall deposition of metabolic substances (amyloid, calcium), nutritional deficiencies (scurvy), nonvasculitic inflammatory purpura (pigmented purpuric dermatitis, arthropod, viral and drug reactions), degeneration of the vessel wall and supporting stroma (senile/solar purpura), direct vessel wall invasion of infective organisms, coagulation-fibrinolytic disorders (eg, thrombocytopenia), and vessel wall trauma. Cyanotic-infarctive pseudovasculitis is due vaso-occlusion by emboli, thrombi, or fibrointimal hyperplasia (endarteritis obliterans) and includes varied conditions such as purpura fulminans, Coumadin necrosis, antiphospholipid antibody syndrome, cardiac myxoma, cholesterol embolization, calciphylaxis, and radiation arteritis. Delayed and inappropriate diagnosis of pseudovasculitis leads to incorrect management and exposure to potentially deleterious treatment modalities such as corticosteroids and cytotoxic agents. The diagnosis of a pseudovasculitic disorder requires a high index of suspicion and should always be part of the differential diagnosis of vasculitis. Skin biopsy is a crucial step in differentiating pseudovasculitis from authentic vasculitis; absence of histologic evidence of vasculitis, particularly after multiple biopsies, should direct evaluation and diagnosis towards pseudovasculitis.

Abstract
BACKGROUND Cholesterol embolism (CE) is an increasingly common but often underdiagnosed medical problem. The recognition of clinical manifestations of CE is the first step toward a correct diagnosis. OBJECTIVE Our aim was to characterize the features of CE and the risk factors for fatal outcome. METHODS Clinical records of patients with clinical and histopathologic diagnoses of CE seen from January 1993 through March 2003 were reviewed. RESULTS Twenty-six male patients were identified. Mean age was 64 years (range, 48-88 years). All patients had two or more risk factors for atherosclerosis. All but one patient had preexisting symptomatic atherosclerotic disease. At least one precipitating factor was identified in 23 patients (88%). Diagnosis of CE at admission was made in 9 patients only (35%). Cutaneous lesions (88%) and renal failure (73%) were the most common clinical findings. Complications (dialysis, acute pulmonary edema, amputation, or gastrointestinal surgery) were present in 21 patients (81%), and 15 patients died (58%). Previous chronic renal failure was the only variable associated with mortality (relative risk: 4.54, 95% confidence interval 1.26-16.6; P = .02). LIMITATIONS The results were obtained from patients admitted to a university hospital. This fact may have selected a higher proportion of severe cases. CONCLUSIONS CE was frequently misdiagnosed. Skin lesions were the most common clinical findings and skin biopsy provided histologic confirmation in most of the patients. Chronic renal failure was the only factor related to death.

Abstract
Cholesterol crystal embolism is a multisystem disorder with a high mortality. It is usually seen following vascular surgery and long term anticoagulation therapy, but the diagnosis is often not considered. Skin manifestations are the first sign of cholesterol crystal embolism and recognition of the symptoms is a key element in early diagnosis and prevention of recurrences. We report a case who presented with acute renal failure, livedo reticularis and skin necrosis following angioplasty. Cutaneous biopsy revealed cholesterol crystals in the lumen of a vessel. Necrotic sites were treated with daily wound care and he was operated for reconstruction of tissue defects with cutaneous advancement flaps. One month after the operation healing was complete.

Abstract
BACKGROUND Atherosclerotic renal artery disease increasingly is recognized as a cause of chronic kidney disease and associated with high morbidity and mortality. We investigated factors predicting patient and renal survival in a cohort of patients with atherosclerotic renal artery disease diagnosed by means of magnetic resonance angiography (MRA). METHODS We retrospectively analyzed a cohort of patients attending our unit in whom atherosclerotic renal artery disease was identified by means of MRA from 1998 to 2001. One hundred nine patients were followed up for a median of 2.3 years. Baseline clinical and laboratory data were assessed as predictors of outcome by using multivariate Cox proportional hazards analysis. RESULTS Seventeen patients (16%) required dialysis and 37 patients (34%) died during a median follow-up of 841 days (interquartile range, 326 to 1,206). On multivariate Cox proportional hazards analysis, increased peripheral-blood eosinophil count (hazard ratio, 3.39; 95% confidence interval [CI], 1.45 to 7.88; P = 0.0097), creatinine clearance (hazard ratio, 0.97; 95% CI, 0.94 to 0.99; P = 0.0128), and peripheral arterial disease (hazard ratio, 2.09; 95% CI, 1.04 to 4.18; P = 0.0371) were associated with subsequent death. Only creatinine clearance (hazard ratio, 0.91; 95% CI, 0.87 to 0.96; P = 0.0004) was associated with the need for dialysis. There was no association between eosinophil count and other markers of inflammation. Severity of atherosclerotic renal artery disease was not associated independently with either the need for dialysis or death. CONCLUSION An increased peripheral-blood eosinophil count predicts patient survival in those with atherosclerotic renal artery disease at the time of diagnosis. This novel risk factor may help identify a group of patients who could benefit from intensive medical therapy by using an assay readily available to most clinicians worldwide.
