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 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 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.

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.

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.

Rheumatoid vasculitis usually occurs in patients with long standing, seropositive, erosive rheumatoid arthritis. It involves typically small to medium-sized vessels and is associated with peripheral neuropathy, digital gangrene, nail fold infarcts, livedo reticularis, and palpable purpura. Histologic examination of skin biopsy specimens usually shows leukocytoclastic vasculitis. We report a case of rheumatoid vasculitis developed on both extremities in a 63-year-old female with rheumatoid arthritis for 15 years.

Cholesterol embolism is due to dislodgment of cholesterol crystals from the atheromatous aorta resulting in an occlusion of small arteries. Cholesterol emboli may occur spontaneously but usually develops as a complication of vascular procedures. The organs most frequently involved are the skin and the kidneys but any organ can be affected. Cutaneous manifestations include livedo reticularis, indurated firm violaceous painful plaques and noduli tending to show central necrosis and tender blue toes. We report two cases of cutaneous cholesterol embolization of lower extremities with the impairment of renal function after coronary angiography, proven by skin biopsy.

A 31-year-old woman had a livedo reticularis of reticulated, bluish discoloration on both arms and legs for 18 months with a burning pain in the right hand and numbness in both lower legs. The findings of the electromyography were consistent with mononeuropathy multiplex and bilateral ulnar-median nerve anastomosis. A biopsy specimen from the right sural nerve showed perivascular lymphocytic infiltration and occasional myelin digestion chambers, which were consistent with vasculitic neuropathy. We present a patient with livedo reticularis idiopathica associated with mononeuropathy multiplex syndrome who also has bilateral ulnar-median nerve anastomosis.
