Adrenocortical carcinoma, abbreviated ACC, is a malignant tumour of the adrenal gland cortex.

It is also known as adrenal cortical carcinoma.

General

  • A tumour of both children and adults.
  • Prognosis poor, especially in adults.

Epidemiology:

Gross

  • +/-Encapsulated.
  • Necrotic-appearing.

Microscopic

Various criteria exist for this diagnosis. The most widely used is the Weiss criteria, which is a big long clunker. This area is prone to regular re-jiggering of criteria and a literature update or expert opinion is recommended prior to signing out one of these rare lesions.

In general:

  • Adrenocortical adenomas are small, circumscribed and have cells with largely bland nuclei and abundant foamy clear or pink cytoplasm.
  • Adrenocortical carcinomas are large, infiltrative, have fibrous bands and necrosis, and cells with less cytoplasm and more atypia including atypical mitotic figures.
  • Adrenocortical adenomas in children; however, can look really ugly.

Notes:

  • Tumour may contain fat.[2]

Adult

Weiss criteria

Three of the following:[3][4]

  1. High nuclear grade.
  2. High mitotic rate; >5/50 HPF (@ 40X obj.) - definition suffers from HPFitis.
  3. Atypical mitoses.
  4. Cleared cytoplasm in >= 25% of tumour cells.
  5. Sheeting (diffuse architecture) in >= 1/3 of tumour cells.
  6. Necrosis in nests.
  7. Venous invasion.
  8. Adrenal sinusoid invasion; lymphovascular space invasion within the adrenal gland.
  9. Capsular invasion.

Volante criteria

There is a simplified set of criteria by Volante et al. - that is not widely used:[5]

  • Reticular network disruption (with reticulin staining).
  • One of the three following:
    1. Abundant mitoses >5/50 high-power fields - definition suffers from HPFitis.
    2. Necrosis.
    3. Vascular invasion.

Pediatric

The criteria in the pediatric setting are somewhat different. This is discussed by Wieneke et al.[6] and Dehner and Hill.[7]

Dehner and Hill propose a very simple system:[7]

  • "Low risk" < 200 g & confined to the adrenal.
  • "Intermediate risk" 200-400 g, no mets, +/-microscopic disease outside adrenal.
  • "High risk" >400 g, or mets, or gross invasion of adjacent structures.

IHC

  • SF-1 +ve.[8][9]
  • Vimentin +ve.
  • Melan A +ve.
  • Inhibin-alpha +ve.
  • Cytokeratins +ve/-ve.
  • p53 +ve.
  • Ki-67 >5%.
    • Typically 1-2 in adrenal cortical adenomas.[10]

Others:

A panel that may be useful for adenoma versus adrenal cortical carcinoma:[10][14]

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