In addition, recent updates of pathology staging for ACC allow adrenocortical carcinoma pathology outlines of prognostic grouping for planning treatment of the patients with ACC.

Adrenocortical carcinoma pathology outlines

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. Furthermore, not all grossly or radiologically identified adrenal cortical lesions may be the source of aldosterone excess. Adrenal cortical carcinomas are subtyped based on their morphological features to include conventional, oncocytic, myxoid, and sarcomatoid subtypes. Although the classic histopathologic criteria for diagnosing adrenal cortical carcinomas have not changed, the WHO classification underscores the diagnostic and prognostic impact of angioinvasion vascular invasion in these tumors. In addition to well-established Weiss and modified Weiss scoring systems, the new WHO classification also expands on the use of other multiparameter diagnostic algorithms reticulin algorithm, Lin—Weiss—Bisceglia system, and Helsinki scoring system to assist the workup of adrenal cortical neoplasms in adults. Accordingly, conventional carcinomas can be assessed using all multiparameter diagnostic schemes, whereas oncocytic neoplasms can be assessed using the Lin—Weiss—Bisceglia system, reticulin algorithm and Helsinki scoring system. Pediatric adrenal cortical neoplasms are assessed using the Wieneke system. The WHO classification places an emphasis on an accurate assessment of tumor proliferation rate using both the mitotic count mitoses per 10 mm 2 and Ki67 labeling index which play an essential role in the dynamic risk stratification of affected patients. Kibased tumor grading has not been endorsed in the new WHO classification, since the proliferation indices are continuous variables rather than being static thresholds in tumor biology.

This pattern may also contain areas of micronodules A. Maintenance between March 11 and 12 may cause some brief downtime. The latter are flat or cuboidal mesothelial cells, devoid of atypia. The necrotic area is not stained up blue arrow. J Clin Res Pediatr Endocrinol. The pathological correlates of adrenal cortical proliferations include diffuse adrenal cortical hyperplasia, adrenal cortical nodular disease, adrenal cortical adenomas and adrenal cortical carcinomas [ 1 ]. These micronodules are often cortisol-producing and composed of lipid-poor cortical cells normally located to the zona fasciculata or to the zona fasciculata-reticularis junction [ 5 ]. Macroscopically, in contrast to conventional ACC with yellow cut sections, the tumour is tan or brown on cut sections Figure 5. Download PDF. Suresh B. In addition, the myxoid stroma make the identification of invasive areas another Weiss parameter difficult. These sex hormone-producing ACCs are mainly androgens. A plot of the pooled-up follow-up data available in the literature of all the cases of oncocytic, myxoid and sarcomatoid variants confirmed that patients with oncocytic ACC had the best prognosis Figure 7.

Because all oncocytic tumors are lipid poor, CT, MRI or PET imaging are unable to distinguish benign from malignant lesions regardless of size, attenuation or handling of the contrast agent.
