Carcinoid heart disease is a well‐known complication of carcinoid syndrome that affects morbidity and mortality. Carcinoid heart disease may be asymptomatic in the early stages; therefore, patients with carcinoid syndrome should be screened to prevent misdiagnosis.

Antiphospholipid syndrome (APS) classically presents with venous or arterial thrombosis and pregnancy morbidity. Although clinical manifestations with fever of unknown origin and intracardiac masses are unusual, in a patient with prolonged fever and multiple intracardiac thrombi, systemic inflammatory diseases such as APS should be considered.
