Pericardial amyloidosis is a rare cause of pericardial effusion. Here, we report a case of recurrent pericardial effusion because of pericardial amyloid deposition. The patient was a man in his 40s admitted for pulmonary embolism. During hospitalization, arterial fibrillation and cardiac tamponade were observed, and an initial pericardial puncture was performed. Thereafter, pericardial puncture was repeated nine times over the next two years. Cytological examination of the pericardial effusion suggested malignant mesothelioma. Afterward, pericardial fenestration and partial resection were performed. Intraoperatively, a thickened pericardium and hemorrhagic pericardial effusion were noted. Histologically, the surface of the pericardium was covered by an eosinophilic amorphous material. Congo red and DYLON stains, electron microscopy, and immunohistochemical findings revealed localized amyloidosis composed of an immunoglobulin lambda light chain. Although the patient did not receive further treatment for 5 years postoperatively, his renal and cardiac functions remained within normal limits. Based on these findings, the patient was diagnosed with localized amyloidosis. So far, hemorrhagic pericardial effusion has been reported in few cases with systemic amyloidosis. Because localized immunoglobulin light-chain-derived (AL) amyloidosis may progress to systemic disease (although it is a very rare occurrence), long-term follow-up is necessary to detect recurrence or progression to a systemic form.
