Epithelial cell adhesion molecule 1 (EpCAM) is an epithelial membrane glycoprotein, often used as a surrogate pan-epithelial marker. To compare the expression patterns of EpCAM and pankeratin antibody (CKpan), gold standard detection, tissue microarrays containing 11,053 samples from 101 different tumor types were analysed by immunohistochemistry. staining was detectable in 99 (82.5%) 120 tumou...

Pediatric adrenocortical tumors (ACT) are rare and often fatal malignancies; little is known regarding their etiology and biology. To provide additional insight into the nature of ACT, we determined the gene expression profiles of 24 pediatric tumors (five adenomas, 18 carcinomas, and one undetermined) and seven normal adrenal glands. Distinct patterns of gene expression, validated by quantitat...

A 9-year-old, spayed female Chihuahua was presented with a 1-week history of lethargy and anorexia. Abdominal ultrasonography and computed tomography found bilateral adrenal masses without metastasis. Serum cortisol levels that were sampled before and after an adrenocorticotropic hormone stimulation test were within reference ranges. Lethargy and anorexia completely resolved after short-term fl...

BACKGROUND Adrenocortical carcinoma is a rare cancer, with an incidence in the literature of 0.5 to 2 cases per million population per year. Adult adrenocortical carcinoma has a poor prognosis, underscoring the importance of identifying diagnostic and prognostic markers. METHODS We searched our laboratory database for all cases in the past 15 years with a diagnosis of adrenocortical carcinoma...

OBJECTIVE This article aims to show the imaging characteristics of pediatric adrenocortical tumors. MATERIAL AND METHODS We review the imaging and histological findings in patients diagnosed with pediatric adrenocortical tumors at our tertiary hospital between 2000 and 2010. We analyze the findings at ultrasonography, computed tomography, and magnetic resonance imaging that can help orient th...

Deregulation of microRNA (miRNA) expression in adrenocortical carcinomas (ACCs) has been documented to have diagnostic, prognostic, as well as functional implications. Here, we evaluated the mRNA expression of DROSHA, DGCR8, DICER (DICER1), TARBP2, and PRKRA, the core components in the miRNA biogenesis pathway, in a cohort of 73 adrenocortical tumors (including 43 adenomas and 30 carcinomas) an...

INTRODUCTION In this report, we describe a rare case of papillary thyroid carcinoma with adrenocortical carcinoma without excess hormone production. CASE PRESENTATION A 40-year-old Turkish man was admitted to our institution with a large left adrenal mass that was identified during the work-up for shortness of breath. The patient did not have specific signs and symptoms of hormone excess. The...

Adrenocortical tumors consist of benign adenomas and highly malignant carcinomas with a still incompletely understood pathogenesis. A total of 46 adrenocortical tumors (24 adenomas and 22 carcinomas) were investigated aiming to identify novel genes involved in adrenocortical tumorigenesis. High-resolution single nucleotide polymorphism arrays (Affymetrix) were used to detect copy number alterat...
