Endocarditis marántica con embolia sistémica como manifestación de adenocarcinoma papilar de pulmón / Nonbacterial thrombotic endocarditis with systemic embolism as a manifestation of papillary lung adenocarcinoma

Resumen: Se presenta el caso de un hombre de 61 años, portador de un cáncer pulmonar en quien lesiones de aspecto embólico llevan al diagnóstico de Endocarditis marántica (no infecciosa). Se describen las características clínicas del paciente, los métodos diagnósticos incluyendo imágenes ecocardiográficas y la confirmación necrópsica.

Abstracts: A 61-year-old male with skin lesions suggesting embolic phenomena, was thoroughly investigated and a final diagnosis of marantic (non-infectious) endocarditis was established. Clinical characteristics and diagnostic investigation through laboratory test and images sustained the diagnosis. The use of transesophageal echocardiography is emphasized. This was finally confirmed by findings at necropsy.

Accidente cerebrovascular embólico por endocarditis de Libman-Sacks como manifestación inicial de síndrome antifosfolípidos primario en una paciente de 17 años: Report of one case / Libman-Sacks endocarditis associated with antiphospholipid syndrome

Libman-Sacks endocarditis is a non-infectious valvular damage associated with autoimmune disorders such as Systemic Lupus Erythematosus and Antiphospholipid Syndrome. We report a 17-year-old female consulting in the emergency room due to a right hemiparesis and aphasia. A magnetic resonance imaging showed multiple infarctions in the territory of the left middle cerebral artery, presumably of embolic origin. A trans-esophageal echocardiogram showed a vegetation in the mitral valve. Blood cultures were negative. Antinuclear antibodies and serological tests for antiphospholipid syndrome were positive. Oral anticoagulation was started and the patient was discharged. After six months of follow up, antiphospholipid antibodies are still positive.
