Adrenocortical carcinoma, abbreviated ACC, is a malignant tumour of the adrenal gland cortex.
It is also known as adrenal cortical carcinoma.
General
- Prognosis poor, especially in adults.
Epidemiology:
- May be associated with a syndrome:[1]
Gross
- +/-Encapsulated.
- Necrotic-appearing.

ACC - cytology (WC/AFIP)
Microscopic
Various criteria exist for this diagnosis. The most widely used is the Weiss criteria, which is a big long clunker.
Notes:
- Tumour may contain fat.[2]
Images
ACC - low mag. (WC/Nephron)
ACC - intermed. mag. (WC/Nephron)
ACC - high mag. (WC/Nephron)
ACC with normal adrenal medulla - high mag.

Adult
Weiss criteria
Three of the following:[3]
- 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:[4]
- 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.[5] and Dehner and Hill.[6]
Dehner and Hill propose a very simple system:[6]
- "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
- Vimentin +ve.
- Melan A +ve.
- Inhibin-alpha +ve.
- Cytokeratins +ve/-ve.
Others:
- Synaptophysin +ve/-ve.
- Chromogranin A -ve.
- Pheochromocytoma +ve.
- EMA -ve.
- Renal cell carcinoma +ve.
- S100 -ve.
- Pheochromocytoma +ve (sustentacular cells).[7]
- PAX-8 -ve.[8]
- CD10 +ve/-ve -- cannot be used to differentiate from RCC.[9]
