Types according to grade

- adrenal cortical adenoma (ACA )
- adrenal cortical carcinoma (ACC )

Types according to secretion

- non-secreting adrenocortical tumor
- androgens-secreting adrenocortical tumor

- cortisol-secreting adrenocortical tumor

Types according to age

- pediatric adrenal cortical tumors


- Weiss Score (WS) system

  • The pathologic diagnosis of adrenocortical carcinoma (ACC) still needs to be improved, because the renowned Weiss Score (WS) system has a poor reproducibility of some parameters and is difficult to apply in borderline cases and in ACC variants.

- reticulin algorithm (23774167)

  • The "reticulin algorithm" (RA) defines malignancy through an altered reticulin framework associated with 1 of the 3 following parameter: necrosis, high mitotic rate, and vascular invasion.
  • Reticulin staining is a reliable technique and an easy-to-interpret system in adrenocortical tumors. 23774167)
  • It has a high interobserver reproducibility, which supports the notion of using such a method in the proposed 2-step RA approach for ACC diagnosis. 23774167)


- 17q22-24 LOH (PRKAR1A locus) (14500362)

Gene mutations

- somatic mutations in the PRKAR1A gene (14500362)
