For these reasons, and because overdiagnosis of recurrent venous thrombosis often results in unnecessary prolongation of anticoagulant treatment, every effort should be made to confirm a diagnosis of suspected recurrence.The reason for the unusual localization of the lesions to subcutaneous fat deposits remains a mystery.Case records of the Massachusetts General Hospital—weekly clinicopathological exercises: case 11-1990, a 38-year-old woman with fever, skin lesions, thrombocytopenia, and venous thromboses.
