Libman-Sacks verrucous endocarditis

Verrucous endocarditis with valvular vegetations (arrows) in a 52-year-old woman with systemic lupus erythematosus who died of pneumonia and chronic interstitial pneumonitis. The vegetations had not been observed by echocardiography, although a cardiac murmur had been heard by auscultation. A cerebrovascular accident was also found at autopsy.
