Marantic endocarditis and adenocarcinoma of unknown primary site.

Nonbacterial thrombotic endocarditis (NBTE) is a disease characterized by deposition of thrombi and fibrin on normal or degenerated cardiac valves in the absence of microorganisms. This condition is more commonly seen in chronic inflammatory states, and is associated with higher incidence of thromboembolic events than infective endocarditis. We report the case of a 63-year old male patient with adenocarcinoma of unknown primary site and systemic embolism.
