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.

It is well demonstrated that adrenal tumours are higher in incidence in women [ ] which is likely to result from the gender difference in hormonal interactions involving complex adrenal, endocrine and neurocrine functions as well as variations in hormonal receptor sensitivity, adrenocortical carcinoma pathology outlines.

Federal government websites often end in. The site is secure. Adrenocortical carcinoma ACC is a heterogenous group of diseases with different clinical behaviour between adult and paediatric patients. 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. To conclude, all these advances in the field of pathology will improve development of management strategies including improvement of clinical care, development of prognostic markers and testing of novel therapeutic approaches for patients with adrenocortical carcinoma.

BMC Nephrol. ENSAT network. Studies used to establish historical guidelines of ACC have suffered from small sample sizes and use of low-resolution computed tomography and inclusion of purely surgical series [ ]. Conventional Adrenocortical Carcinoma 2. This photomicrograph illustrates p53 overexpression in a high-grade adrenal cortical carcinoma. Adrenal cortical carcinoma: adrenal cortical carcinoma myxoid oncocytic sarcomatoid. Microarray gene expression and immunohistochemistry analyses of adrenocortical tumors identify IGF2 and Ki as useful in differentiating carcinomas from adenomas. Adrenocortical carcinoma ACC is a heterogenous group of diseases with different clinical behaviour between adult and paediatric patients. Table 1 Characteristics of different types of Adrenocortical carcinoma. Management of adrenocortical carcinoma in Western Australia: A perspective over 14 years. In the literature, 4 cases had a rhabdomyosarcoma component [ , , , ] and 3 had osteosarcoma component [ , , ]. Non-functioning adrenal cortical carcinoma presenting with metastasis to the tongue. Weissferdt A.

Adrenocortical carcinoma ACC is a rare tumor with a poor prognosis. Most tumors are either metastatic or locally invasive at the time of diagnosis.

Arch Endocrinol Metab — Nat Commun However, we cannot answer medical or research questions or give advice. Schematic overview of genetic differences between adrenal cortical adenoma and carcinoma. A variety of immunohistochemical and molecular biomarkers have been evaluated diagnostically and prognostically in ACCs [ 18 , , , , , ]. Other than these, patients with sarcomatoid ACC often presented with localized pain abdominal pain, loin pain, flank pain, back pain, etc. Whole-exome sequencing characterizes the landscape of somatic mutations and copy number alterations in adrenocortical carcinoma. While parasitic cysts are related to Echinococcus infections, endothelial cysts develop from dilated and thrombosed blood or lymphatic vessels, and epithelial cysts are associated to mesothelial remnants [ 63 ]. Adrenal cortical choristoma is a related term to adrenal ectopia and is defined as mature adrenal cortical elements whose location cannot be explained with the normal embryogenesis of adrenal cortex. Wang S. Aldosterone producing cortical lesions can be unifocal or multifocal, and may be bilateral with no imaging-detected nodule s. In: Edge S. In addition, large tumour size and cortisol-secreting tumour were additional factors for ACC-specific death [ 49 ]. From that perspective, the use of SF1 immunohistochemistry Fig.
