The heart wall (schematic). (WC/Wikiversity Journal of Medicine)

Pericardium is a specimen that uncommonly comes to pathology.

Pathologies of the pericardium

Benign

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]

Gross

Features:[3]

Notes:

  • Normal pericardial fluid volume 5-35 mL.[3]

Microscopic

Features:

  • Inflammatory cells:
    • Neutrophils.
    • Lymphocytes.
    • Plasma cells.
  • +/-Hemosiderin-laden macrophages.

Sign out

PERICARDIUM, BIOPSY:
- ACUTE AND CHRONIC PERICARDITIS WITH SIDEROPHAGES AND REACTIVE MESOTHELIAL CHANGES.
- NO MICRO-ORGANISMS SEEN WITH ROUTINE STAINING.
- NO EVIDENCE OF MALIGNANCY.

Micro

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.
