ABSTRACT
Cushing syndrome is a pro-thrombotic state that contributes to an increase in mortality. The antiphospholipid syndrome is characterized by repetitive thrombosis associated with the presence of autoantibodies against phospholipids or membrane proteins. Their association has not yet been described. We report the case of a 47 year old patient in whom the hormonal exploration of an adrenal incidentaloma led to the diagnosis of Cushing syndrome. He returned five years later with cerebral thrombophlebitis, bilateral lower limbs phlebitis and bilateral pulmonary emboli. An antiphospholipid syndrome was confirmed by positive anti-cardiolipin and anti-beta2 glycoproteine-I antibodies. The patient recovered after anti-coagulant treatment and resection of the adrenal adenoma. Thrombo-embolic complications during Cushing syndrome, especially when severe and extensive, must lead to the search for another acquired thrombotic condition, especially the antiphospholipid syndrome
