Cardiac Angiosarcoma-Associated Membranoproliferative Glomerulonephropathy

Abstract EN

Primary cardiac angiosarcoma is a rare cardiac tumor.

The initial clinical course is often asymptomatic, and metastatic disease is present in a majority of affected patients at diagnosis.

We present a patient who presented with a hemorrhagic pericardial effusion.

No malignant cells were evident on cytological examination.

He subsequently developed membranoproliferative glomerulonephritis requiring hemodialysis.

Metastatic cardiac angiosarcoma was diagnosed 5 months later.

To our knowledge, this is the first reported case of paraneoplastic membranoproliferative glomerulopathy associated with cardiac angiosarcoma.
