Ozgur Mete, Sylvia L Asa, Thomas J Giordano, Mauro Papotti, Hironobu Sasano, Marco Volante
Careful morphological evaluation forms the basis of the workup of an adrenal cortical neoplasm. However, the adoption of immunohistochemical biomarkers has added tremendous value to enhance diagnostic accuracy. The authors provide a brief review of immunohistochemical biomarkers that have been used in the confirmation of adrenal cortical origin and in the detection of the source of functional adrenal cortical proliferations, as well as diagnostic, predictive, and prognostic biomarkers of adrenal cortical carcinoma...

Autophagy plays a vital role in embryonic development and cell differentiation. Our previous study demonstrated that prenatal ethanol exposure (PEE) resulted in intrauterine growth retardation (IUGR) and adrenal developmental toxicities in rat offspring. The present study focused on PEE-induced autophagy as an underlying mechanism and its biological significance in female fetal rats. Female fetuses in the PEE group exhibited lower body weights and suffered adrenal structural abnormalities compared to the controls...

With fewer than 200 reported cases, Cushing's syndrome (CS) in pregnancy remains a diagnostic and therapeutic challenge. In normal pregnancies, misleading signs may be observed such as striae or hypokalemia, while plasma cortisol and urinary free cortisol may rise up to 2-3-fold. While the dexamethasone suppression test is difficult to use, reference values for salivary cortisol appear valid. The predominant cause is adrenal adenoma (sometimes without decreased ACTH), rather than Cushing's disease. There are considerable imaging pitfalls in Cushing's disease...

We investigated time-dependent changes in the relapse features of renal cell carcinoma (RCC) after curative surgery. Between 1985 and 2015, 1398 patients with RCC (1226 clear cell RCC, 89 papillary RCC, and 53 chromophobe RCC) underwent curative surgery at Yokohama City University Hospital and its affiliated hospitals. We retrospectively reviewed the clinicopathologic factors of patients with relapse after surgery. Median follow-up was 56.3 months. Recurrence occurred in 245 patients (217 clear cell RCC, 12 papillary RCC, and 3 chromophobe RCC)...

BACKGROUND: Adrenocortical carcinoma (ACC) is a rare, heterogeneous malignancy with a poor prognosis. ACCs are classified as functioning and non-functioning. The pathogenesis of ACC remains elusive, and diagnosis of ACC is currently based on pathology. In the absence of other effective approaches, surgical resection is the preferred treatment option. CASE PRESENTATION: Here, we report a case of ACC in the retroperitoneum. The patient underwent radical adrenalectomy and remained disease-free throughout a 6-month follow-up...

INTRODUCTION: Black adrenal adenoma (BAA) is a rare, benign adrenal lesion with a black or brown appearance. This is the first report of this lesion in a patient with a synchronous esophageal cancer and highlights the importance of considering a false positive finding on a Positron Emission Tomography (PET) scan, which might otherwise preclude resection. PRESENTATION OF CASE: A 73-year-old male was diagnosed with mid-esophagus carcinoma. Computed tomography scan revealed an enlarged left adrenal gland...

BACKGROUND: Carcinosarcoma of the liver is a very rare tumor composed of a mixture of carcinomatous and sarcomatous elements. Less than 25 adequately documented cases have been reported, with inadequate description of imaging features. In order to improve the awareness of this rare tumor, this study aimed to analyze the clinicopathologic and imaging features of six cases of hepatic carcinosarcoma (HCS) confirmed by surgical pathologic evaluation. METHODS: We retrospectively studied the clinicopathologic and imaging features of six cases of HCS (matching the World Health Organization definition) and discussed the differential diagnosis on the basis of imaging findings...

Adrenocortical carcinoma (ACC) is a rare malignancy with a poor prognosis, the five-years overall survival being below 40%. However there is great variability of outcomes and we have now a better view of the heterogeneity of tumor aggressiveness. The extent of the disease at the time of diagnosis, best assayed by the European Network for the Study of Adrenal Tumors (ENSAT) staging score, is a major determinant of survival. The tumor grade, including the mitotic count and the Ki67 proliferation index, also appears as a strong prognostic factor...

CONTEXT: the recent recommendations of the European endocrine society states that the performance of computed tomography (CT) to characterize true adrenal incidentalomas (AIs) remains debatable. OBJECTIVE: to determine relevant thresholds for usual CT parameters for the diagnosis of benign tumors using robust reference standard amongst a large series of "true" AIs recruited in an endocrinological setting. DESIGN: retrospective study of 253 AIs in 233 consecutive patients explored in a single university hospital: 183 adenomas, 33 pheochromocytomas, 23 adrenocortical carcinomas, 5 other malignant tumors and 9 other benign tumors...

Adrenocortical carcinoma is a very rare and aggressive endocrinological malignancy arising from the adrenal cortex. The estimated incidence is 1 per million people, with an estimated 5-year survival rate of 16-47%. It can be bilateral in roughly 2-10% of cases, but the data is scarce and there is no conclusive evidence whether the contralateral mass is an independent tumor or a metastasis from the other adrenal gland cancer. Radical surgical excision is the only curative treatment. Therefore, careful pre- and intraoperative surgical planning is critically important...

INTRODUCTION: In the MEN 2A syndrome, which is the most common of the three types of MEN, three endocrine systems are affected simultaneously or subsequently by the development of tumours manifested by medullary thyroid gland carcinoma, pheochromocytoma (often bilateral) and hyperparathyroidism. MATERIAL AND METHODS: 27 patients from 3 families affected by MEN 2A syndrome were examined clinically (by detecting the effects of catecholamine overproduction), biochemically (screening for metanephrine and normetanephrine in the serum), visualization (CT, MRI, MIBG, PET CT) and some of them also genetically (DNA fragment analysis obtained by PCR amplification)...

BACKGROUND: B-Cell CLL/Lymphoma 9 (BCL9) is a recently described oncogene that promotes tumorigenesis via activation of the Wnt/β-Catenin signaling cascade. Though constitutively active Wnt/β-Catenin signaling is a molecular hallmark of adrenocortical carcinoma (ACC), a potential role for BCL9 to promote Wnt/β-Catenin pathway dysregulation in adrenocortical tumorigenesis remains to be elucidated. STUDY DESIGN: This study involved a retrospective analysis at a tertiary academic referral center of 27 patients with adrenocortical tumors, including in vitro investigation of BCL9...

Oncocytic tumors are epithelial neoplasms that occur in various organs, including adrenal glands. Oncocytic adrenocortical adenomas and carcinomas are uncommon but well-known pathological entities in adults. However, generally oncocytic tumors, particularly in the adrenal glands, are very rare in the pediatric age-group. Most oncocytic adrenal tumors are not functional. We present a rare case of right-sided, functional oncocytic adrenocortical adenoma in a 5-year-old boy, who presented with clinical manifestations of precocious puberty and Cushing syndrome...

Vimentin is a cytoskeletal intermediate filament protein that is expressed in mesenchymal cells and cancer cells during the epithelial-mesenchymal transition. The goal of this study was to identify vimentin-targeting small molecules by using the Tocriscreen library of 1120 biochemically active compounds. We monitored vimentin filament reorganization and bundling in adrenal carcinoma SW13 vimentin-positive (SW13-vim+) cells via indirect immunofluorescence. The screen identified 18 pharmacologically diverse hits that included 2 statins-simvastatin and mevastatin...

Intravascular tumor extension, also known as tumor thrombus, can occur in many different types of cancer. Those with the highest proclivity include Wilm's tumor, renal cell carcinoma (RCC), adrenal cortical carcinoma (ACC) and hepatocellular carcinoma (HCC). The presence of tumor thrombus markedly worsens prognosis and impacts treatment approach. Imaging plays a key role in its diagnosis. Endovascular methods also play a large role in treatment.

Hypervascular adrenal masses include pheochromocytoma, metastases caused by clear renal cell carcinoma/hepatocellular carcinoma. Alveolar soft part sarcoma (ASPS) causing hypervascular metastases is not described in the literature. Here, we describe the first case of ASPS presenting as hypervascular metastasis. Our case was a 23-year-old male incidentally detected right adrenal mass during the evaluation of pain in the abdomen. On computed tomography (CT), adrenal mass showed bright enhancement in early arterial phase (unenhanced Hounsfield unit [HU]-45...

Multiple endocrine neoplasia type 2A (MEN2A) is a hereditary syndrome. Here, two different RET proto-oncogen mutation were identified from family members of two MEN2A pedigrees by genetic screening. One RET mutations were found at codons 1893 and 1895 in exon 11 (1893-1895delCGA) from pedigree 1, which is a novel mutation, the other occurs at codon 634 (Cys634Arg) in exon 11 from pedigree 2. However, the clinical characteristics were similar in the patients of the two pedigrees. All the patients were in middle-age at onset...
