[Non-bacterial thrombotic endocarditis as paraneoplastic manifestation of pulmonary adenocarcinoma].

Non bacterial thrombotic endocarditis is characterized by the presence of non infected vegetation in aortic or mitral valves associated with systemic arterial emboli. Non-bacterial thrombotic endocarditis is a common complication of neoplastic diseases: adenocarcinoma of the lung, another adenocarcinomas, myeloma, lymphoma, leukemia, carcinoma of the pancreas, breast, cervix, colon and stomach. We report a case of non-bacterial thrombotic endocarditis localized in the aortic and mitral valves and systemic emboli as the first manifestation of adenocarcinoma of the lung.
