Incidences and prognoses of adrenal tumors.[1]

Adenoma versus carcinoma

The most common adrenal tumors are adrenocortical adenomas and carcinomas. These are most commonly distinguished by the Weiss system,[2] as follows:[3]

Characteristic[3] Score
High nuclear grade (enlarged, oval to lobated, with coarsely granular to hyperchromatic chromatin and easily discernible, prominent nucleoli)[4] 1
More mitoses than 5/50 high power fields 1
Atypical mitoses 1
Eosinophilic cytoplasm in >75% of tumor cells 1
Diffuse architecture of >33% of tumor 1
Necrosis 1
Venous invasion 1
Sinusoidal invasion (no smooth muscle in wall) 1
Capsular invasion 1

Total score indicates:[3]

  • 0-2: Adrenocortical adenoma
  • 3: Undetermined
  • 4-9: Adrenocortical carcinoma
