Cardiac tumours
Cardiac tumours are rare buggers. They provide some work for cardiac surgeons.
Most common malignant
- Metastases - most common cardiac tumour; 1:~100 primary tumours:secondary tumours.[1]
Primary heart tumours
- Approximately 10% of resected (primary) cardiac tumours are malignant.[2]
- 90% are sarcomas.
- 10% are lymphomas.
In order of frequency:
Notes:
- If one is considering only valves - papillary fibroelastoma is No. 1.
Malignant heart tumours (in order of frequency):[1]
- Undifferentiated.
- Angiosarcoma.
- Leiomyosarcoma.
Note:
- According to WMSP:[3] Most common primary malignant tumour of the heart = angiosarcoma.
Specific entities
Cardiac myxoma
Main article: Cardiac myxoma
This includes the common atrial myxoma.
Papillary fibroelastoma
General
- Usually an incidental finding.
Gross
- Friable appearing.
- Yellow.
- Typically on free edge.
Image:
Microscopic
Features:[6]
- Braching papillary fronds which are:
- Composed of collagen, and
- Avascular.
- +/-Elastic tissue.
- Surrounded by:
- Endothelium, and
- Mucopolysaccharide.

Cardiac rhabdomyoma
Main article: Rhabdomyoma
- Very rare.
- Benign.
- Associated with tuberous sclerosis.[7]
Rhabdomyosarcoma
See rhabdomyosarcoma.
Lipoma
Main article: Adipocytic tumours
- Like lipomas elsewhere in the body.
- Usually location: left ventricle, subendocardial.[3]
DDx:
- Lipomatous hypertrophy.[8]
Cystic tumour of the atrioventricular nodal region
General
- Super rare.[9]
- Usually 1-2 mm.
- May cause sudden cardiac death.[10]
Gross
- "Bump" in the triangle of Koch.
- Cystic spaces.
Microscopic
Features:[10]
- Cystic spaces lined single layer of epithelial cells.
- +/-Focal mononuclear inflammation.
- +/-Psammoma bodies.
