Hughes-Stovin syndrome

Hughes-Stovin syndrome (HSS) is an extremely rare disorder characterized by the combination of pulmonary artery aneurysms and deep vein thrombosis (peripheral venous thrombosis or thrombophlebitis). First described by Drs. John Patterson Hughes and Peter George Ingle Stovin in 1959, the condition is considered by many experts to be a variant of Behçet disease, as both conditions share overlapping features of vasculitis affecting vessels of all sizes. The syndrome predominantly affects young males, typically presenting between the second and fourth decades of life. The disease primarily affects the cardiovascular and pulmonary systems. Pulmonary artery aneurysms are the hallmark feature and represent the most life-threatening complication, as rupture can lead to massive hemoptysis (coughing up blood) and potentially fatal hemorrhage. Patients commonly present with cough, hemoptysis, fever, dyspnea (shortness of breath), and chest pain. Deep vein thrombosis, often involving the lower extremities or intracranial venous sinuses, typically precedes or accompanies the pulmonary manifestations. Some patients may also develop thrombosis of the superior or inferior vena cava. There is no established standardized treatment protocol for Hughes-Stovin syndrome due to its rarity. Management is largely based on expert opinion and case reports. Immunosuppressive therapy, including corticosteroids and cyclophosphamide or other immunosuppressants such as azathioprine, is the mainstay of treatment aimed at controlling the underlying vasculitis and preventing aneurysm progression. Anticoagulation therapy for thrombosis must be used with extreme caution, as it may increase the risk of fatal hemorrhage from pulmonary artery aneurysms. In select cases, surgical intervention or endovascular embolization may be considered for large or expanding aneurysms. Early diagnosis and aggressive immunosuppressive treatment have improved outcomes, but the prognosis remains guarded, particularly if pulmonary aneurysm rupture occurs.
