Abstract

Sneddon's syndrome consists of livedo reticularis and cerebral vascular accidents with no evidence of systemic disease responsible for the livedo. The syndrome has been assimilated to a subgroup of systemic lupus erythematosus (SLE) with presence of antibodies directed against phospholipids. Recently, a significant increase in the frequency of cardiac valve diseases has been demonstrated in some SLE patients with livedo reticularis, cerebral vascular accidents and antiphospholipid antibodies. We report the case of a 26-year old woman who had been presenting for 6 years with idiopathic livedo reticularis. Her history was remarkable for the occurrence of 2 cerebral ischaemic accidents at the ages of 23 and 26 years, generalized convulsive seizures at 22 years, and hypertension of pregnancy with 2 miscarriages. Biopsy of the livedo showed normal histological patterns, but electron microscopy detected an obliterating endothelial proliferation and endothelial cells with numerous Weibel-Palade bodies. Laboratory signs of SLE, as well as antiphospholipid antibodies were absent. At the age of 26 years, cardiac abnormalities were heard at auscultation for the first time, and echocardiography showed that they were due to a fairly loose mitral stenosis. According to Burton's criteria our patient had all the typical features of Sneddon's syndrome. The finding of mitral stenosis--an emboligenic cardiopathy that is potentially responsible for cerebral vascular accidents--raises the problem of its relationship with Sneddon's syndrome. The association does not seem to be fortuitous, since our case is very similar to the cases of SLE or antiphospholipid antibody syndrome associated with cardiac valve lesions. However, this case is particular in that 6 years after the onset of the disease there was still no sign of SLE and of antiphospholipid antibodies.(ABSTRACT TRUNCATED AT 250 WORDS)
