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. Aldosterone producing cortical lesions can be unifocal or multifocal, and may be bilateral with no imaging-detected nodule s.

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.

Indian J Endocrinol Metab — Aldosterone-producing adrenal cortical adenomas especially those harboring KCNJ5 mutations typically have a canary golden yellow appearance [ 1 ]. Accessed March 8th, Images hosted on other servers: Discohesive, round to polygonal tumor cells. Informed Consent Statement Not applicable. Protocols for pathological reporting of adrenal gland tumours is not new and have been used in different countries such as Australia which developed a protocol of adrenal tumour in the year [ ]. Papathomas T. Consent for Publication All authors consent to publication. Mitotic figures are often prominent. The pathological correlates of adrenal cortical proliferations include diffuse adrenal cortical hyperplasia, adrenal cortical nodular disease, adrenal cortical adenomas and adrenal cortical carcinomas. Adrenal cortical rests and choristomas share immunohistochemical features of adrenal cortical cells as they express SF1 and other non-specific biomarkers of adrenal cortical differentiation [ 22 , 51 , 59 , 60 ]. Most patients with bilateral micronodular adrenocortical disease carry pathogenic germline variants in genes normally associated with the regulation of the protein kinase A PKA pathway involved in the physiological response to ACTH stimulation [ 4 , 5 ]. Invasion of large blood vessels renal vein or vena cava as thrombus, previously considered as M1 in AJCC 7th edition is now classified as T4. Nihon Geka Gakkai Zasshi. Reduced adrenal cortical thickness in association with significantly reduced to absent zona reticularis layer is a diagnostic feature of adrenal cortical atrophy [ 1 , 5 , 15 ] Fig.

Kibased tumor grading has not been endorsed in the WHO classification of adrenal cortical carcinomas, since the proliferation indices are continuous variables rather than being static thresholds in tumor biology. Protocol Posting Date: November Bisceglia M. Oncocytic ACC with Conn syndrome aldosterone secreting without other hormonal changes was reported in detail only in a year-old man from Canada [ ]. In addition, oncocytic tumours that are positive for synaptophysin and negative for vimentin are more often benign [ ]. RH mutation. Preliminary data also shows that for localised ACC, molecular makers expression, methylation, and chromosome alterations could predict cancer recurrence [ 9 ]. However, endocrine atypia should not be mistaken for nuclear atypia. Other tumors: adenomatoid tumor metastases myelolipoma. A variety of immunohistochemical and molecular biomarkers have been evaluated diagnostically and prognostically in ACCs [ 18 , , , , , ]. Myxoid variant of adrenocortical carcinoma ACC is characterized by the presence of extracellular myxoid component.
