Heart failure with multiple cardiac masses: Extensive cardiac involvement in Rosai-Dorfman disease

Rosai-Dorfman disease (RDD) is a non-malignant disease. Pathologically it is characterised by histiocytic proliferation. A typical clinical presentation is painless generalised lymphadenopathy. Extra nodal involvement can be seen in 20-40% of cases. Cardiac involvement is rare and suggests a poor prognosis. We report a case of RDD with extensive cardiac involvement, initially masquerading as multiple cardiac thrombi in the background of underlying antiphospholipid antibody syndrome.
