title: Sneddon syndrome associated with Protein S deficiency.
abstract: Sneddon syndrome (SS) is rare, arterio-occlusive disorder characterized by generalized livedo racemosa of the skin and various central nervous symptoms due to occlusion of medium-sized arteries of unknown. Seizure, cognitive impairment, hypertension, and history of repetitive miscarriages are the other symptoms seen in this disease. Livedo racemosa involves persisting irreversible skin lesions red or blue in color with irregular margins. Usually, SS occurs in women of childbearing age. Protein S deficiency is an inherited or acquired disorder associated with an increased risk of thrombosis. We present a 33-year-old woman with SS with diffuse livedo racemosa, recurrent cerebrovascular diseases, migraine-type headache, sinus vein thrombosis, and protein S deficiency. Protein S deficiency and with Sneddon syndrome rarely encountered in the literature.
