In addition, recent updates of pathology staging for ACC allow refinement of prognostic grouping for planning treatment of the patients with ACC. These advances in genomic, pathology and staging have driven the development of standardisation of pathology reporting. International standardisation of pathological reporting of adrenocortical carcinoma and adaption to local pathology communities provide universal platforms for clinicians and researchers involved in the management of patients with ACC.

Adrenocortical carcinoma ACC is a rare tumor with a poor prognosis. Most tumors are either metastatic or locally invasive at the time of diagnosis. Differentiation between ACC and other adrenal masses depends on clinical, biochemical, and imaging factors. This review will discuss the genetics, pathological, and imaging feature of ACC.

The new WHO classification of adrenal cortical proliferations reflects translational advances in the fields of endocrine pathology, oncology and molecular biology. By adopting a question—answer framework, this review highlights advances in knowledge of histological features, ancillary studies, and associated genetic findings that increase the understanding of the adrenal cortex pathologies that are now reflected in the WHO classification. The pathological correlates of adrenal cortical proliferations include diffuse adrenal cortical hyperplasia, adrenal cortical nodular disease, adrenal cortical adenomas and adrenal cortical carcinomas. Understanding germline susceptibility and the clonal-neoplastic nature of individual adrenal cortical nodules in primary bilateral macronodular adrenal cortical disease, and recognition of the clonal-neoplastic nature of incidentally discovered non-functional subcentimeter benign adrenal cortical nodules has led to redefining the spectrum of adrenal cortical nodular disease. As a consequence, the most significant nomenclature change in the field of adrenal cortical pathology involves the refined classification of adrenal cortical nodular disease which now includes a sporadic nodular adrenocortical disease, b bilateral micronodular adrenal cortical disease, and c bilateral macronodular adrenal cortical disease formerly known primary bilateral macronodular adrenal cortical hyperplasia. This group of clinicopathological entities are reflected in functional adrenal cortical pathologies.

Although the studies differ in terms of case numbers and techniques employed, adrenal cortical carcinomas adhere to either low-, intermediate-, or high-risk clusters when profiling their mutational, expressional, DNA methylation, and gross chromosomal landscapes Fig. Kovecsi A. Chandrasekar T. Among various locations, adrenal cortical choristomas have also been described within TPIT-lineage pituitary neuroendocrine tumors corticotroph PitNETs [ 50 , 51 ]. Cambridge University Press, Cambridge. Endocr Rev — Conflicts of Interest The author declares no conflict of interest. Recently, in , the criteria have been validated by Picard and colleagues in 95 paediatric adrenal cortical neoplasms from France [ 83 ]. Clinical series from adult and pediatric adrenal cortical carcinomas underscored the prognostic role of Ki67 in both adult and pediatric adrenal tumors [ , , , , ].

Malignant epithelial tumor of adrenal cortical cells with predominantly oncocytic morphology. In addition, gelatinous myxoid areas were noted [ , ]. Adrenal ectopia.

Clin Endocrinol Oxf — Tickoo: In the past, ultrastructure examination has helped in the distinction of aldosterone-producing adrenal cortical proliferations from other steroidogenic adrenal cortical lesions by assessing characteristics of the mitochondrial cristae. It is often not difficult to differentiate ACC from benign cortical adenoma or borderline cortical tumour. Similar to p53, nuclear beta-catenin expression may be identified in a subset of adrenal cortical carcinomas which are typically enriched in high-grade carcinomas that are reflected in poor-prognostic molecular clusters.
