Cystic medial degeneration (abbreviated CMD), also cystic medial necrosis,[1] is vascular pathology of the large blood vessels suggestive of an underlying connective tissue disorder.
General
- Nonspecific finding - may be seen in a number of conditions.
Note about cystic medial necrosis:
- Often not cystic and not necrotic.
Microscopic
- Basophilic ground substance in the media (seen on Movat's stain).
- Disruption of the elastic lamina (seen on elastic trichrome stain).
- +/-Focal necrosis.

Stains
- Elastin stains (e.g. elastic trichrome stain) - disruption of the elastic lamina.
- Movat's stain - basophilic ground substance in the media.
