Pericardium is a specimen that uncommonly comes to pathology.
Pathologies of the pericardium
Benign
- Idiopathic pericarditis - common.[1]
- Infectious pericarditis - post-procedural.
- Fibrinous pericarditis.
- Pericardial cyst.
Malignant
Related pathologies
- Pericardial effusion.
- Hemopericardium.
- Cardiac tamponade.
Specific entities
Idiopathic pericarditis
- Pericarditis redirects here.
General
- Uncommon.
- In the clinical context pericarditis is used for things that probably don't have inflammation.[2]
- "Pericardial heart disease" may be a better descriptor.
Etiologies of pericarditis:[3]
- Infectious:
- Fungal.
- Bacterial.
- Idiopathic - most common.
- Neoplastic.
- Autoimmune, e.g. systemic lupus erythematosus.
- Uremia - chronic renal failure.
- Traumatic - post-surgical.
- Associated with myocardial infarction - Dressler's syndrome.
Gross
Features:[3]
- Thickening.
- +/-Pericardial effusion.
Notes:
- Normal pericardial fluid volume 5-35 mL.[3]
Microscopic
Features:
- Inflammatory cells:
- Neutrophils.
- Lymphocytes.
- Plasma cells.
- +/-Hemosiderin-laden macrophages.
DDx:
- Infectious pericarditis.
- Malignant mesothelioma.[1]

The sections show fibrous tissue with minimal adipose tissue that is covered by mesothelium. A mixed inflammatory infiltrate is present that consists primarily of lymphocytes and plasma cells. Rare eosinophils are seen. Focally, neutrophils are seen and associated with reactive mesothelial cells. Abundant hemosideratin-laden macrophages are seen. No fibrinous strands are seen. No significant nuclear atypia is identified and no atypical infiltrative cell population is identified. No micro-organisms are identified with routine staining.
