Abstract
Stewart–Bluefarb syndrome is a rare angioproliferative disorder characterised by acroangiodermatitis associated with an underlying arteriovenous shunt. This condition should be differentiated from acroangiodermatitis of Mali classically described in association with chronic venous insufficiency. Patients with Stewart–Bluefarb syndrome typically present with lower leg pigmented macules, papules and plaques that can coalesce to form larger confluent patches of pigmentation. Recognition of Stewart–Bluefarb syndrome may be difficult or delayed as the cutaneous manifestations may resemble a variety of other dermatological conditions. Most commonly, acroangiodermatitis may be confused with Kaposi’s sarcoma and the condition is often referred to as ‘Pseudo-Kaposi’s sarcoma’. Acroangiodermatitis may also resemble or coexist with pigmentation of chronic venous insufficiency. As seen in this report, acroangiodermatitis may also be clinically confused with the ‘cavernous’ form of a capillary malformation. Here, we describe five patients with Stewart–Bluefarb syndrome. In one female and two male patients the diagnosis was delayed as the acroangiodermatitis closely resembled other conditions. All underlying arterio-venous communications were initially diagnosed on duplex ultrasound and confirmed with magnetic resonance angiography. Four patients were found to have a congenital arterio-venous malformation while one was diagnosed with a post-thrombotic arterio-venous fistula. Management included observation and intervention using a variety of techniques including percutaneous or trans-catheter embolisation, endovenous laser, radiofrequency ablation and foam ultrasound guided sclerotherapy. This case series highlights the challenges involved in the diagnosis and management of Stewart–Bluefarb syndrome. Given the local and systemic sequelae of high flow shunts, correct diagnosis and early detection of the underlying arterio-venous abnormality is crucial in the long-term management of these patients and in preventing the associated complications.

Abstract
Stewart-Bluefarb syndrome (SBS), also known as acroangiodermatitis or pseudo-Kaposi, is a condition rarely encountered. It involves skin lesions that are clinically similar to Kaposi sarcoma but are histologically different, and are usually secondary to an underlying arteriovenous fistula. Treatment of this disease usually involves the correction of the underlying vascular abnormality, with the mainstay of therapy ranging from compression devices for venous stasis, limited oral medications (dapsone and erythromycin) and local wound care including topical steroids. Different methods of treatment showed varied success but none is ideal. We report a case of a lower extremity ulcer in a 22-year-old male recently diagnosed with SBS successfully treated with heparan sulphate (Cacipliq20®).

Abstract
Vascular malformations are rare but important skin disorders in children, which often require multidisciplinary care. The goal of this article is to orient pediatricians to the various types of vascular malformations. We discuss the clinical characteristics, diagnostic criteria, and management of capillary, venous, arteriovenous, and lymphatic malformations. Associated findings and syndromes are also discussed briefly.

Abstract
Cholesterol embolism (CE) is characterized by emboli containing cholesterol crystal in the arterioles, most commonly found in the skin and the kidney. The skin presentations of CE include livedo reticularis, blue toe syndrome, ulceration and gangrene. Cutaneous reactive angiomatosis (CRA) is a recently proposed term to describe a group of reactive vascular proliferation in skin caused by various diseases. Its occurrence in association with CE is extremely uncommon. An 82-year-old man with a history of cerebral infarction and on long-term warfarin therapy developed progressive, multiple violaceous papules and nodules on the dorsal feet, soles and toes, simulating Kaposi's sarcoma. Skin biopsy showed marked vascular endothelial cell proliferations characteristic of CRA affecting the full thickness of dermis. In addition, cholesterol crystal emboli were found in dermal arterioles. The skin lesions improved after the warfarin dose was reduced. We emphasize the possible presence of CE in a patient presented with CRA, especially in those with a pre-existing atherosclerotic disease, on anticoagulation therapy, or having a prior history of invasive vascular procedure.

Abstract
We describe the rare Stewart-Bluefarb syndrome in a 15-year-old boy. This syndrome presents as a congenital arteriovenous malformation of the lower leg with multiple arteriovenous shunts accompanied by the benign acroangiodermatitis of Mali (pseudo-Kaposi's sarcoma). The clinical features of this disorder and the treatment options are reviewed.

Abstract
UNLABELLED Cutaneous vascular malformations are rare disorders representing errors in vascular development. These lesions occur much less commonly but are often confused with the common infantile hemangioma. It is important to properly diagnose vascular malformations because of their distinct differences in morbidity, prognosis and treatment. Vascular malformations may be associated with underlying disease or systemic anomalies. Several of these syndromes are well defined and can often be distinguished on the basis of the flow characteristics of the associated vascular malformation. LEARNING OBJECTIVE At the completion of this learning activity, participants should have a better understanding of the different types of cutaneous vascular malformations. Because of the importance of proper diagnosis of these lesions, participants should also be better able to direct correct management and treatment.

Abstract
Growth of the limb in a child can be impaired, with the coexistence of a vascular malformation. In these vascular bone syndromes, altered growth is manifest as overgrowth or hypotrophy. The vascular malformation is usually complex and gets progressively worse with time. The two types of vascular anomalies in limbs, fast-flow and slow-flow, can be associated with limb length discrepancies. The fast-flow vascular malformations together with arteriovenous fistulae are part of Parkes Weber syndrome, characterized by congenital red cutaneous staining, hypertrophy in girth and increasing of limb length, lymphedema, increasing skin alterations due to a distal vascular steal, and pain, all of which develop during childhood. Treatment is generally conservative. An affected lower extremity can be complicated by pelvic tilting and scoliosis because leg length discrepancy may reach 10 cm. To avoid such a course, stapling epiphysiodesis of the knee cartilages is often performed, but this orthopedic procedure may augment the worsening of the arterial venous malformation in the limb. Therefore, less aggressive orthopedic management is preferable. Slow-flow vascular anomalies associated with limb growth alteration include (1) a diffuse capillary malformation (port-wine stain) with congenital hypertrophy of the involved extremity which is non-progressive; (2) purely venous malformations invading skin, muscles and joints, with pain, functional impairment, a chronic localized intravascular coagulopathy requiring distinctive management, and usually a slight undergrowth of the affected extremity and progressing amyotrophy; (3) the triad of a port-wine stain, anomalous veins and overgrowth of the limb, often known as Klippel-Trenaunay syndrome, which requires orthopedic management to decide the optimal timing for epiphysiodesis (i.e. when leg length discrepancy is >2.5 cm). Varicose veins are sometimes surgically removed after ultrasonographic and Doppler evaluation has confirmed a normal deep venous system. Capillary malformations can be effectively treated with pulsed dye laser, but results are usually poor in distal extremities.

Abstract
Cutaneous vascular proliferations are a vast and complex spectrum. Many appear as hamartomas in infancy; others are acquired neoplasms. Some vascular proliferations are hyperplastic in nature, although they mimic hemangiomas, i.e., neoplasms. The vast majority of the vascular lesions are hemangiomas. Between the hemangiomas and frankly angiosarcomas, there is a group of neoplasms that are angiosarcomas, albeit ones of low grade histologically and, probably, biologically. The term "hemangioendothelioma" has been created to encompass these neoplasms. Vascular proliferations are, fundamentally, composed of endothelial cells. Some hemangiomas, however, contain also abundant pericytic, smooth muscle, or interstitial components, or a combination of them. These heterogeneous cellular components are present usually in hemangiomas. Some of the newly described vascular proliferations, however, are difficult to differentiate from some of the angiosarcomas. Others are markers, occasionally, of serious conditions such as Fabry's Disease (angiokeratoma) and POEM's syndrome (glomeruloid hemangioma). Kaposi's sarcoma continues to be an enigma. The demonstration of Herpes virus 8 in this condition raises doubt about its neoplastic nature. The demonstration of endothelial differentiation of its nodular lesions is tenuous and its true nature remains unresolved. While physicians have known about post-mastectomy angiosarcomas from the origin of the radical mastectomy, a new group of unusual vascular proliferations of the mammary skin are being defined. These lesions arise in the setting of breast-conserving surgical treatment with adjuvant radiation therapy. The incubation period is usually 3 to 5 years, in contrast with the 10, or more, in classical cases of post-mastectomy angiosarcoma. These lesions usually are subtle, both clinically and histologically, in contrast with the "classical," dramatic presentation of mammary angiosarcoma. The spectrum of findings ranges from "simple" lymphangiectasia-like vascular proliferations to unequivocal angiosarcomas. The pathogenesis of these lesions remains a mystery. There are very few clues that allow one to separate hemangiomas from angiosarcomas. The presence of heterologous cellular elements and, particularly, well-developed smooth muscle components tends to favor a hemangioma. Similarly, the presence of thrombosis usually supports hemangioma. Nevertheless, there are no unequivocal or reliable individual diagnostic criteria. A thorough knowledge of the different conditions and their differential diagnoses eventually leads to the proper diagnosis in most cases.

Abstract
Kaposi's sarcoma (KS) is a mesenchymal tumour involving blood and lymphatic vessels. Only recently has the pathogenesis of this extraordinary neoplasm been elucidated. Viral oncogenesis and cytokine-induced growth together with some state of immunocompromise represent important conditions for this tumour to develop. In 1994, a novel virus was discovered and termed human herpesvirus 8 (HHV8), also known as Kaposi's sarcoma-associated herpes virus, which can be found in all types of KS, whether related to HIV or not. In the era of highly active antiretroviral therapy (HAART), the incidence of AIDS-KS has considerably declined, probably due to enhanced immune reconstitution and anti-HHV8-specific immune responses. If HAART is able to prevent spreading of KS, local therapy of KS may become an essential component of patient management. Part 1 of the review covers the epidemiology, environmental predispositions, clinical manifestations, and therapy of KS. Newer treatments such as pegylated liposomal anthracyclines and experimental strategies are discussed. We also present rationales and graduated treatment algorithms for local and systemic therapy in patients with KS to appropriately meet the challenges of this extraordinary neoplasm. Part 2, to be published next month, will summarise recent insights in the pathogenesis of KS and will discuss other HHV8-related diseases such as Castleman's disease and primary effusion lymphoma.
