====Cortex====
Radiology<ref>[http://emedicine.medscape.com/article/376240-overview]</ref>
It has three layers - mnemonic: '''GFR''' (from superficial to deep):
*radiologists are good at identifying adenomas, as they are usually lipid rich and have a characteristic low HU signal.
#Zona glomerulosa - salt (e.g. aldosterone).
#*Eosinophilic cytoplasm. (???)
#*Layer normally discontinuous.
#Zona fasciculata - sugar (e.g. cortisol).
#*Clear cytoplasm - '''key feature'''.
#*Largest part of the cortex ~ 70%.
#*Cells in cords/nests. (???)
#Zona reticularis - steroid (e.g. dehydroepiandrosterone).
#*Marked eosinophilia of cytoplasm - '''key feature'''.
#*Granular/reticular cytoplasm.

Note:
*lesions >30 mm
*Normal cortex may not be completely encapsulated, i.e. the adrenal capsule may have defects.<ref>{{Ref_H4P4|1236}}</ref>
*hormonally active
**In other words: the cortex may "spill" into the surrounding fat.
*non-incidental finding (?)


===Hyperplasia vs. adenoma===
====Medulla====
*Hyperplasia is multifocal.<ref>IAV 18 Feb 09.</ref>
It consists of two cell types:<ref name=Ref_PBoD8_1159>{{Ref PBoD8|1159}}</ref>
#Chromaffin cells.
#*Arise of neural crest.
#Sustentacular cells (supporting cells).


Produce ''NED'': norepinephrine, epinephrine, dopamine.

A drawing of the adrenal glands.

Adrenal gland is a little organ that hangs-out above the kidney. Pathologists rarely see it. It uncommonly is affected by tumours.

Anatomy & histology

Adrenal cortical rest redirects here.

Anatomy

  • Cortex.
  • Medulla.

Note:

  • Adrenal tissue may be associated with gonads or between gonads and adrenal gland proper.[1]

Microscopic

It is composed of a cortex and a medulla.

Cortex

It has three layers - mnemonic: GFR (from superficial to deep):

  1. Zona glomerulosa - salt (e.g. aldosterone).
    • Eosinophilic cytoplasm. (???)
    • Layer normally discontinuous.
  2. Zona fasciculata - sugar (e.g. cortisol).
    • Clear cytoplasm - key feature.
    • Largest part of the cortex ~ 70%.
    • Cells in cords/nests. (???)
  3. Zona reticularis - steroid (e.g. dehydroepiandrosterone).
    • Marked eosinophilia of cytoplasm - key feature.
    • Granular/reticular cytoplasm.

Note:

  • Normal cortex may not be completely encapsulated, i.e. the adrenal capsule may have defects.[2]
    • In other words: the cortex may "spill" into the surrounding fat.

Medulla

It consists of two cell types:[3]

  1. Chromaffin cells.
    • Arise of neural crest.
  2. Sustentacular cells (supporting cells).

Produce NED: norepinephrine, epinephrine, dopamine.

Images

  • Adrenal medulla. (WC)

  • Adrenal cortex & medulla (right of image), and tumour (left of image). (WC/Nephron)

  • Adrenal rest - low mag. (WC/Nephron)

  • Adrenal rest - intermed. mag. (WC/Nephron)

  • Adrenal rest - high mag. (WC/Nephron)

IHC

Adrenal cortex:[4]

  • Chromogranin A -ve.
  • Synaptophysin +ve.
  • Alpha-inhibin +ve.
  • Vimentin +ve.
  • Melan A +ve.
  • AE1/AE3 -ve.
  • RCC -ve (0 +ve of 63 cases[5]).
  • EMA -ve (0 +ve of 63 cases[5]).

A panel that may be useful for adenoma versus carcinoma:[6][7]

  • Beta-catenin, p53, reticulin, inhibin, melan A, Ki-67.

Clinical

Patients getting a bilateral adrenalectomy get pre-treatment with steroids.[8]

Adrenal insufficiency is an immediate danger post-op.[9]

Benign

The section covers non-neoplastic pathologies of the adrenal gland. These uncommonly come to the pathologist.

  • Adrenal incidentalomas[10]
    • Adrenal tumors
    • Greater than 1 cm
    • Identified on imaging performed for other indications
  • Found in up to 10% of patients undergoing abdominal imaging.
  • Management problematic
    • Guidelines incorporate lesion size, functional status and imaging features.
    • Resection is generally advocated for
      • Functioning lesions.
      • Radiographic features suggestive of malignancy.
      • Growth during observation.

DDx (autopsy):

  • Post-mortem changes.

Microscopic

Features:

  • Massive haemorrhage within the substance of the adrenal gland.

Adrenal cytomegaly

  • AKA adrenocortical cytomegaly.
  • AKA adrenal gland with cytomegaly.

General

May be associated with:[14]

Microscopic

Features:

  • Large cells in the adrenal cortex.[15]

Addison disease

General

  • Chronic adrenocortical insufficiency.

Clinical:

  • Brown skin - due POMC (a precursor of ACTH and melanocyte stimulating hormone (MSH)).[16]
  • Hypotension.
  • Nausea and vomiting.

DDx:[17]

Notes:

  • Secondary adrenocortical insufficiency (due to pituitary pathology):[18]
    • No hyperpigmentation (as no POMC).
    • Aldosterone usu. normal.

Microscopic

Features:[16]

  • Atrophy adrenal cortex - specifically zona fasciculata and zona reticularis.

Notes:

  • There is preservation of zona glomerulosa and medulla.

Benign neoplasms

Adrenal hemangioma

Radiographic incidentalomas but may be large and calcified raising a radiographic ddx of adrenal cortical carcinoma.

  • Rare.
  • 40 and 70 years.
  • 2:1 female-to-male ratio
