Abstract Background Severe cardiac sarcoidosis (CS) can share clinical and histopathologic features with giant cell myocarditis (GCM). Case summary A 56-year-old female presented with 1 week of exertional chest pressure and dyspnoea. Echocardiogram demonstrated extensive regional dysfunction with left ventricular ejection fraction (LVEF) 38%. Cardiac catheterization revealed no obstructive coronary artery disease and cardiac index 1.5 L/min/m2. Cardiac magnetic resonance imaging (MRI) demonstrated diffuse late gadolinium enhancement. Positron emission tomography with fluorodeoxyglucose (FDG) (FDG-PET) computed tomography showed FDG uptake in the anteroseptal and anterior wall and no extracardiac activity. Endomyocardial biopsy (EMB) demonstrated fragments of endocardial fibrosis with mixed inflammatory infiltrate including histiocytic giant cells, which could be due to CS or GCM. She was initially treated for GCM with high dose steroids, tacrolimus, and mycophenolate mofetil. Repeat EMB was pursued and demonstrated multiple granulomas with sharp demarcation from adjacent uninvolved myocardium consistent with CS. A dual-chamber implantable cardioverter-defibrillator was placed, and immunosuppression was changed to prednisone alone with plan for infliximab. Discussion This case illustrates a rare presentation of fulminant isolated CS. Endomyocardial biopsy with sufficient tissue was critical to establish a diagnosis and initiate appropriate immunosuppression.

Pathologic Basis

Sarcoidosis is a rare disease of isolated or diffuse granulomatous inflammation. Although any organs can be affected by sarcoidosis, cardiac sarcoidosis is a fatal disorder, and it is crucial to accurately diagnose it to prevent sudden death due to dysrhythmia. Although endomyocardial biopsy is invasive and has limited sensitivity for identifying granulomas, it is the only modality that yields a definitive diagnosis of cardiac sarcoidosis. It is imperative to develop novel pathological approaches for the precise diagnosis of cardiac sarcoidosis. Here, we aimed to discuss commonly used diagnostic criteria for cardiac sarcoidosis and to summarize useful and novel histopathologic criteria of cardiac sarcoidosis. While classical histologic observations including noncaseating granulomas and multinucleated giant cells (typically Langhans type) are the most important findings, others such as microgranulomas, CD68+ CD163− pro-inflammatory (M1) macrophage accumulation, CD4/CD8 T-cell ratio, Cutibacterium acnes components, lymphangiogenesis, confluent fibrosis, and fatty infiltration may help to improve the sensitivity of endomyocardial biopsy for detecting cardiac sarcoidosis. These novel histologic findings are based on the pathology of cardiac sarcoidosis. We also discussed the principal histologic differential diagnoses of cardiac sarcoidosis, such as tuberculosis myocarditis, fungal myocarditis, giant cell myocarditis, and dilated cardiomyopathy.

Abstract Introduction Cardiac involvement by sarcoidosis, a disease characterized by nonnecrotizing granulomas of unknown etiology, is rare and affects up to 7% of sarcoidosis patients clinically, but with an autopsy prevalence of 15% to 90%. The clinical presentation, as well as macroscopic and microscopic findings in cardiac sarcoidosis patients, varies. Methods Retrospective clinical chart review and gross and microscopic examination of surgical specimen from two adult cardiac sarcoidosis patients with literature review were performed. Results Case 1: A 23-year-old woman with no past medical history presented with 2 months of heart failure symptoms following a viral gastrointestinal infection. Endomyocardial biopsy showed a dense chronic inflammatory infiltrate, without giant cells. Anterior mediastinal lymph node biopsy and left apical core showed effacement by nonnecrotizing granulomas with giant cells and multifocal calcification, supporting cardiac sarcoidosis. Twelve months later, she underwent cardiac transplantation. The explanted heart showed concentric ventricular scarring, which microscopically corresponded to myocardial fibrosis with scattered lymphocytic inflammation with no residual granulomas. Case 2: A 52-year-old man with a medical history significant for ischemic cardiomyopathy and cutaneous sarcoidosis with lung involvement presented with congestive heart failure. Endomyocardial biopsy and left apical core showed myocyte hypertrophy and scattered interstitial inflammation. Mediastinal lymph node showed nonnecrotizing granulomas, consistent with sarcoidosis. Eighteen months later, he underwent cardiac transplantation. The explanted heart showed biventricular dilatation with interstitial fibrosis. There was also mild diffuse inflammation and occasional granulomas with rare focal necrosis. Conclusion Though the gold standard for diagnosing cardiac sarcoidosis is demonstration of myocardial nonnecrotizing granulomas, the sensitivity of endomyocardial biopsy is low. This is due to sampling error and stage of disease. Chronic end-stage disease can lead to fibrous encasement of granulomas and end-stage heart failure, necessitating cardiac transplantation. Current guidelines employ a combination of clinical, radiologic, and histologic criteria for diagnosing cardiac sarcoidosis.
