Zona glomerulosa
THE CELLS
- well defined cells
- Rounded
- acidophilic cytoplasm
- lipid droplets
- secretes mineralocorticoids

#The_yellow_star
Zona fasiculata
THE CELLS
- Broad band of large cells with distinct membranes arranged in cords
- Cytoplasm has numerous small lipid vacuoles
- secretes glucocorticoids

#The_green_star
Zona reticularis
THE CELLS
- Granular and eosinophilic cytoplasm with minimal lipid
- Richly vascularized, capsular blood vessels, nerves and lymphatics penetrate along connective tissue septae
- secretes androgens

A
#Diagnosis 👉🏻  Atrophy adrenal gland
DUE TO Addison’s disease or Long term using of Corticosteroids and stop using it suddenly not gradually

B
#Diagnosis 👉🏻 Normal adrenal gland
• The cortex is yellow in color
• The medulla is red in color

C
#Diagnosis 👉🏻 adrenal hyperplasia
DUE TO Cushing's disease

#Microscopic

#Diagnosis 👉🏻  Adrenal nodular hyperplasia


#The_black_arrows
Nodules

#The_blue_arrows
Lipid poor pink cells like reticulari

#The_red_arrows
Lipid-rich clear cells like fasciculata

NOTES
- The Nodules larger than 3mm ( macronodular )
- metaplasia or atrophic cortex between nodules

#Diagnosis 👉🏻  Adrenocortical adenoma


#The_white_arrow
Adenoma

#The_features
- Circumscribed , Unilateral, solitary
- yellow tan in color
- Hemorrhage
- Functional adenoma may result in atrophy of contralateral adrenal cortex

NOTE
Cause hypertension and hypokalemia

#The_features

• increased variation in nuclear size
• cells have abundant foamy cytoplasm like of zona fasciculata

#Diagnosis 👉🏻   Adrenocortecal carcinoma


#The_black_star
Invasion (Metastases to vein)

#The_blue_arrow
Hemorrhage

#The_features
- Encapsulated tumor 
- Invasion of thick fibrous capsule
- Lymphovascular invasion
- hemorrhage
- hyperchromic nuclei

NOTES
Often are functional and can lead to
- Cushing diseas
- Masculinization in females
- Feminization in male
