#Diagnosis 👉🏻  Papillary carcinoma


#The_white_arrow

#The_green_arrows
Optical clear nuclei ( ground glass nuclei)

#The_blue_arrows
Papillae

#The_black_arrows
Papillae by transfert section

#The_features
Nuclear features
- Change of nuclear size and shape
• nuclear enlargement, elongation
Nuclear overlapping the nuclei are so crowded that they look like they are sitting on one another
Ground glass nuclei : it means the chromatin is finely dispersed and optically clear. This appearance is also known as “Orphan Annie Eye” 
groove nuclei are formed due to folding of  the unessential nuclear membrane
nuclear inclusions
Vascular Nuclei
- Nuclear membrane irregular

Other features
- randomly oriented papillae with fibrovascular cores
- Psammoma body in the fibrovascular cores

#Diagnosis 👉🏻 Medullary carcinoma


#The_blue_arrow

الذي تظهر باللون الوردي

#The_red_arrow
Amyloid

NOTES
• The medullary carcinoma is Neuroendocrine tumor derived from C cells (formerly called parafollicular cells) 
• Painless
• can be sporadic or familial. The familial kind are associated with multiple endocrine neoplasia syndrome.

- 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

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