Down syndrome is the most, well known autosomal trisomy and e large number of abnormal skin features have been reported to occur in patients with Down syndromir. including syringoma. Syringomas occur with increased frequency in patients with Down syringoma, usually limited to the region around the eyes. but few cases of eruptive syringoma with Down syndrome have been reported. We reported the case of familial eruptive syringoma in a 13 years old patient with Down syndrome.

Sneddon's syndrome is a disease characterized by livedo reticularis and cerebrovascular lesions with unknown etiopathogenesis. We report a 16-year-old male patient who had been suffered from livedo reticularis for 10 years and multiple cerebral infarction for 2 years. Although the histologic finding of the skin did not show vasculitis and vascular occlusions, the patient revealed livedo reticularis and central nervous system symptoms. These findings were compatible with Sneddon's syndrome.

Sneddon's syndrome consists of livedo reticularis and ischemic cerebrovascular disease, which was reported by Sneddon in 1965. Althrough the etiology of it is not clear, this syndrome appears frequantly in patient with antiphospholipid antibody or early stage of Systemic Lupus Erythematosus. We report a 32-year-old female patient who had been suffered from livedo reticularis and premature cerebral infarction. VDRL was false positive for over 5 years. These findings were compatible with Sneddon's syndrome.

Livedo reticularis with summer ulceration was first reported by Feldaker et al in 1955, that is characterized by livedo reticularis and ulcerations of the legs or feet beginning primarily the summer or warmer months of the year, and healing the winter months. A 32-year old rnan has suffered from periodic painful ulcerations, which were occurred during the summer, on the both ankles and brown to bluish colored reticulated discoloration on the lower legs for about 10 years. Histopathological findings showed endothelial proliferation and partial occlusion of the dermal capillaries, fibrinoid material on the superficial blood vessels, and partial epidermal necrolysis. This patient. was treated with antiplatelet aggregating medications and antihypertensive drug.

Sneddon's syndrome consists of widespread livedo reticularis and ischemic cerebral manifestations. We report a case of a 70-year-old Korean woman with extensive livedo reticularis, hypertension, positive laboratory results for antinuclear antibodies and the lupus anticoagulant test, and idiopathic Parkinson's disease.

Sneddon's syndrome is an infrequent neurocutaneous disorder of unknown origin. It is characterized by the combination of livedo reticularis and cerebrovascular accident. We present a 57-year-old male patient with livedo reticularis and cerebrovascular accident. Magnetic resonance imaging of the head showed a sign of acute focal infarctions in the right cerebellar hemisphere and right vermis. He had netlike patterned, mottled bluish discoloration on both legs. Histopathologic finding revealed elongation and fusion of rete ridges and mild thickening of dermal capillaries.

Livedo reticularis is a mottled bluish discoloration of the skin which occurs in a netlike pattern and is not a diagnosis in itself, but is a nonspecific reaction pattern. It may be classified as idiopathic and secondary livedo reticularis. Decompression sickness can occur during decompression after diving into deep sea water or during a rapiid ascent from sea level, and is one of the many causes of the secondary livedo reticularis. We report a case of livedo reticulris which developed in a patient with decompression sickness. A biopsy from the purpuric patch revealed an unusual histopathologic finding that resembles those of bullae and sweat gland necrosis in drug induced coma.

Cutaneous cholesterol embolism is a disease with severe arterosclercsis of the abdominal aorta in which emboli of cholesterol crystals from atheromatous plaques occlude airterioles. We report a case of cutaneous cholesterol embolism in a 61-year-old man who had livedo reticularis on both his feet for 10 days. Histopathologic findings showed needle-shaped cholesterol clefts viithin the lumina of arterioles. The patient died of myocardial infarction 3 months later.

Essential thrombocythemia (ET) is a clonal stem cell disease characterized by isolated thrombocytosis and thrombohemorrhagic complications. We describe an unusual case of ET primarly presenting with skin symptoms including erythromelalgia and livedo reticularis (racemosa-type). Persistent thrombocytosis, bone marrow findings, JAK2 gene mutation, and markedly decreased ristocetin-cofactor activity were consistent with the diagnosis of ET and acquired von Willebrand disease. Elevated antiphospholipid antibodies were also found. The present case highlights the complex nature and diagnostic challenge of myeloproliferative disorders such as ET, which can involve multiple organ systems and often shows a variety of microvascular complications, coagulation anomalies, and autoimmune phenomena.

Cutaneous polyarteritis nodosa(CPAN) is a benign form of rare vasculitis of small and medium-size arteries with a recurrent but benign course without systemic involvement. We experienced a 61-year-old male who had two months history of multiple deep-purpurish livedo reticularis on both lower legs. Noncutaneous manifestations including malaise, fever, myalgia, and arthritis were absent. A skin biopsy specimen from the livedo reticularis on the leg showed perivascular and trans-mural neutrophilic and lymphocytic infiltration of medium-sized arteries in the dermal-subcutaneous junction and fibrinoid necrosis of the vessel walls. The patient was treated with colchicine for 2months and showed markded improvement.
