Cushing syndrome, also hypercortisolism, is when there is too much glucocorticoids.
Clinical
The features can be remembered with CUSHING:[1]
- Central obesity + Cervical fat pad + Comedones (acne).
- Unusual brUising.
- Striae.
- Hypertension + Hyperglycemia.
- Immunosuppression.
- Neoplasia may cause it.
- Growth retardation.
A shorter version is CUSH:
- Central obesity with peripheral wasting, Cervical fat pad.
- Unusual brUising.
- Straiae on Skin.
- Hypertension + Hyperglycemia.
Microscopic
Features - pituitary gland:
- Crooke-hyaline change:[2]
- ACTH producing cell: basophilic granular cytoplasm becomes pale and homogenous.
