Degos' disease: radiological and immunological aspects.

We present an 18-year-old patient with Degos' disease who manifested the sudden onset of paraplegia. Neurological examination revealed a rt-hemianopsia, paraparesis (with a sensory level at Th12), and a neurogenic bladder. Brain MRI showed multiple cerebral infarctions accompanied by small hemorrhagic areas and GdDTPA enhancement of the dura. A cerebral angiogram displayed stenosis, ectasia, and aneurysms involving the peripheral branch of arteries. Stenoses also were observed in the celiac artery and small arteries in the 1t-kidney. Skin biopsy exhibited hyperkeratosis, atrophy of the epidermis, and necrobiosis of the collagen layer. Laboratory examinations disclosed persistent elevations of the thrombin-antithrombin III complex (TAT), plasmin-alpha 2 plasmin inhibitor complex (PIC), and cytotoxic T cell subset (CD8+CD11-), illustrating the coagulative, fibrinolytic, and immunological implications of this disease.
