Comprehensiveness
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
- ((Comprehensive))
Presentations
- In autopsy, see Heart autopsy.
Gross processing
- Measure the dimensions of fragments. If multiple, the greatest dimension of each fragment is enough.
- Describe and measure any pathologies, at least the greatest dimension thereof, in particular:
- Suspected bacterial vegetations, such as granular red-brown discolorations.
- Calcifications.
- Look for red-brown discolorations which may be bacterial vegetations.
Gross report
Example:
((A. Labeled - ___. The specimen is received in formalin and consists of)) multiple fragments of tan-white tissue measuring 0.2 to 1.0 cm. Multiple, nodular calcifications are present measuring up to 0.2cm. (Representative sections are submitted for microscopic examination in __ cassettes.) |
Microscopic examination
Look in particular for calcifications and bacterial vegetations.
A vegetation of bacterial endocarditis. In a consistent clinical setting, neutrophils and fibrin is enough to diagnose a bacterial vegetation, even without visible bacterial colonies.[image 1]
Myxomatous degeneration.[1]
