Staining: HE
Organ: Myocardium
Description:
We can see the normal signs of hypertrophic myocardium: interstitial fibrosis, enlarged nuclei and (some) lipofuscin pigment.
In an area almost in the exact middle of the slide is an area where the myocardial cells have lost their orientation.
Diagnosis: Hypertrophic cardiomyopathy
Causes:
- Genetic defects
Theory:
Hypertrophic cardiomyopathy has the same microscopic morphology as simple hypertrophic myocardium, but also has areas where there is loss of orientation. If you have trouble recognizing the slide you can remember the blocky appearance of the upper right corner of the slide.
