Myocarditis is inflammation of the heart.
General
- Uncommon.
Gross
- Not apparent on gross.
Grossing:
- Requires 10 sections to exclude;[1] sections should include right ventricle and left ventricle.
- It is often missed with five.[2]
Microscopic
Features:
- Inflammation.
- Myocyte necrosis (disputed[3]).
Classification
Classified by the inflammatory cells present:[4]
- Eosinophilic - hypersensitivity myocarditis - most common.
- May be assoc. with peripheral blood eosinophilia.[5]
- Lymphocytic - viral, autoimmune.
- Granulomatous - infectious, idiopathic.
- Neutrophilic.
- Reperfusion (associated with myocardial infarction).
Images
- Myocarditis (viral) - 1 (WC).
- Myocarditis (viral) - 2 (WC).
- Eosinophilic myocarditis (jmedicalcasereports.com).[5]
