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. | |||

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:
- May be associated with a syndrome:[1]
Gross
- +/-Encapsulated.
- Necrotic-appearing.
Image:
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]
DDx
Diagnostic categories:
- Large pink polygonal cell neoplasms.
- Retroperitonial large polygonal cell neoplasms.

Adult
Weiss criteria
- High nuclear grade.
- High mitotic rate; >5/50 HPF (@ 40X obj.) - definition suffers from HPFitis.
- Atypical mitoses.
- Cleared cytoplasm in >= 25% of tumour cells.
- Sheeting (diffuse architecture) in >= 1/3 of tumour cells.
- Necrosis in nests.
- Venous invasion.
- Adrenal sinusoid invasion; lymphovascular space invasion within the adrenal gland.
- 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:
- Abundant mitoses >5/50 high-power fields - definition suffers from HPFitis.
- Necrosis.
- 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.
- Rarely positive in adrenal cortical adenomas.[10]
- Ki-67 >5%.
- Typically 1-2 in adrenal cortical adenomas.[10]
Others:
- Synaptophysin +ve/-ve.
- Chromogranin A -ve.
- Pheochromocytoma +ve.
- EMA -ve.
- Renal cell carcinoma +ve.
- S100 -ve.
- Pheochromocytoma +ve (sustentacular cells).[11]
- PAX8 -ve.[12]
- CD10 +ve/-ve -- cannot be used to differentiate from RCC.[13]
A panel that may be useful for adenoma versus adrenal cortical carcinoma:[10][14]
- Beta-catenin, p53, reticulin, inhibin, melan A, Ki-67.
