Adrenal teratomas are rare neoplasms and there is limited data on their surgical outcomes and long-term prognosis. We aimed to review our institutional experience and compare this to the existing literature on adrenal teratomas in adults and children. An institutional pathology database was searched for cases of adrenal teratoma (June 1956-July 2016). Clinical and imaging data were abstracted from the medical records and pathology slides were obtained for review. In addition, a PubMed search for "adrenal teratoma" from June 1952 to July 2016 was performed to identify reports of primary adrenal teratoma in patients of all ages...

Patients with congenital adrenal hyperplasia have a predisposition for developing adrenal rest tumors. In contrast to testicular adrenal rest tumors, ovarian adrenal rest tumors are less common, and only a few cases have been reported in the literature. This report presents three Chinese female congenital adrenal hyperplasia patients (9 to 15 years of age) with small ectopic adrenal cortical nodules that were not detected by imaging but were diagnosed at surgery. All three patients developed virilization with elevation of 17- hydroxyprogesterone, androstenedione, and androgen levels despite receiving maximum adrenal hormone replacement therapy...

Objective: To evaluate the value of single-source dual-energy CT (ssDECT) in differentiating lipid-poor adenomas from metastases in adrenal glands. Methods: From August 2011 to Oct 2014, 63 patients with 73 adrenal nodules (53 metastases proven by 5-6 months follow-up, and 20 histopathologically proven adenomas, CT value > 10 HU) underwent ssDECT scanning. The CT values of conventional polychromatic CT and virtual monochromatic images (40-140 keV) , fat-water density images and effective atomic number (eff-Z) were reconstructed on an ADW4...

CONTEXT: Approximately half of primary aldosteronism (PA) have clinically evident disease according to clinical (hypertension) and/or laboratory (aldosterone and renin levels) findings but do not have nodules detectable in routine cross-sectional imaging. However, the detailed histopathologic, steroidogenic and pathobiological features of cross-sectional image negative PA have not been well characterized. OBJECTIVE: Examine histopathology, steroidogenic enzyme expression and somatic mutation status of aldosterone-driver genes in adrenals from cross-sectional image negative hyperaldosteronism...

BACKGROUND: Ultrasonography to visualize adrenal gland lesions and evaluate incidentally discovered adrenal masses in dogs has become more reliable with advances in imaging techniques. However, correlations between sonographic and histopathological changes have been elusive. The goal of our study was to investigate which ultrasound features of adrenal gland abnormalities could aid in discriminating between benign and malignant lesions. To this end, we compared diagnosis based on ultrasound appearance and histological findings and evaluated ultrasound criteria for predicting malignancy...

OBJECTIVE: The only reliable method for subtyping primary aldosteronism (PA) is adrenal venous sampling (AVS), which is costly and time-consuming. Considering the limited availability of AVS, it would be helpful to obtain information on the diagnosis of bilateral hyperaldosteronism (BHA) from routine tests. We aimed to establish new, simple criteria for outpatients to diagnose BHA from PA before AVS. DESIGN: We retrospectively analysed 82 patients who were diagnosed with PA and underwent AVS...

Skin is an uncommon site for metastasis with only 0.7-9% of all patients with cancer being affected when compared to other organs. Generally, the time lag between the diagnosis of primary malignancy and the recognition of the skin metastases is long, but sometimes these metastases may be the first indication of otherwise clinically silent visceral malignancies as seen in our case. In cholangiocarcinomas, the occurrence of cutaneous metastases is extremely rare. Their most common sites of metastasis are visceral organs i...

Renal cell carcinoma metastases to pancreas, thyroid, and contralateral adrenal gland are decidedly uncommon. Clear cell renal cell carcinoma (CCRCC) is the most frequent subtype. Cytology diagnosis may be challenging. A 74-year-old male with remote history of vocal cord malignancy and hypertension presented with abdominal pain. Computed tomography (CT) revealed 8.4 cm left renal mass highly suspicious for renal cell carcinoma, a 1.8 cm mass within vessels near left adrenal and a 2.5 cm mass in pancreatic tail...

Our group previously purified human and rat aldosterone synthase (CYP11B2 and Cyp11b2, respectively) from their adrenals and verified that it is distinct from steroid 11β-hydroxylase (CYP11B1 or Cyp11b1), the cortisol- or corticosterone-synthesizing enzyme. We now describe their distributions immunohistochemically with specific antibodies. In rats, there is layered functional zonation with the Cyp11b2-positive zona glomerulosa (ZG), Cyp11b1-positive zona fasciculata (ZF), and Cyp11b2/Cyp11b1-negative undifferentiated zone between the ZG and ZF...

BACKGROUND: Lung cancer is the most commonly diagnosed neoplasm in humans, however this does not apply to other animal species. Living in an aquatic environment the respiratory system of cetaceans had to undergo unique adaptations in order to them to survive and cope with totally different respiratory pathogens and potentially carcinogens from those affecting humans. CASE PRESENTATION: This article discusses not only macroscopical, histopathological and immunohistochemical features of a pulmonary carcinoma with disseminated metastases in a long-finned pilot whale (Globicephala melas), as well as the immunohistochemical analysis performed on various tissues of cetaceans belonging to the genus Globicephala...

BACKGROUND: Pulmonary sarcomas are uncommon accounting for 0.5 % of all primary lung cancers. Undifferentiated sarcomas account for up to 20 % of soft tissue sarcomas. A lung tumor revealed to be an undifferentiated sarcoma with epithelioid features has never been reported in the literature. CASE PRESENTATION: A 61-year-old white Moroccan man presented with 2 months' history of hemoptysis and dyspnea. Chest computed tomography showed a cystic mass involving the lower field of his right lung evoking first a hydatid cyst...

Multiple endocrine neoplasia 2A (MEN2A) is characterized by the coexistence of tumors that involve two or more endocrine glands within the same patient, and is defined as the occurrence of medullary thyroid carcinoma in association with pheochromocytoma (PHEO) and parathyroid tumors or hyperparathyroidism. The pathogenesis of MEN2A is due to the mutation of a tyrosine kinase receptor that is encoded by the rearrangement during transfection (RET) proto-oncogene. The mutation often occurs in exon 10q11.2. The present study reports the case of a 73-year-old man with severe hypercalcemia, bilateral adrenal PHEO and a thyroid nodule...

We report a case of a fetus with an ultrasonography diagnosis of a neuroblastoma during a routine third trimester fetal scan, which presented as a hyperechogenic nodule located above the right kidney. No other abnormalities were found in the ultrasonography scan; however, the follow-up ultrasonography during the 36th week of gestation revealed that the lesion had doubled in size. At the same time, magnetic resonance imaging demonstrated a round mass in the topography of the right adrenal gland with a low signal on T1-weighted images and slightly high signal on T2-weighted images, causing a slight inferior displacement of the kidney...

CONTEXT: Recurrent somatic mutations in KCNJ5, CACNA1D, ATP1A1 and ATP2B3 have been identified in aldosterone producing adenomas (APA). The question as to whether they are responsible for both nodulation and aldosterone production is not solved. CASE DESCRIPTION: We describe the case of a young patient who was diagnosed with severe arterial hypertension due to primary aldosteronism at age 26, followed by hemorrhagic stroke four years later. Abdominal computed tomography showed bilateral macronodular adrenal hyperplasia...

PURPOSE: Adrenal ectopy is a rare condition, caused by abnormal embryological development of the adrenal glands and testis. This anomaly is asymptomatic and is generally diagnosed in childhood. Most cases of adrenal ectopy of the groin region have been found incidentally during surgery. This review aims to evaluate the incidence of adrenal ectopy of the adult groin region, as well as its short- and long-term significance. METHODS: A systematic literature search was performed using the EMBASE, MEDLINE, PubMed and Cochrane Central databases to identify all studies published until December 2015...

A 40-year-old man presented with Cushing's syndrome due to bilateral adrenal hyperplasia with multiple nodules. Computed tomography scan results were atypical demonstrating an enlargement of the bilateral adrenal glands harboring multiple small nodules, but the lesion was clinically diagnosed to be primary pigmented nodular adrenocortical disease (PPNAD) based on both endocrinological test results and his family history. We performed bilateral adrenalectomy and confirmed the diagnosis histologically. An analysis of the patient and his mother's genomic DNA identified a novel mutation in the type Iα regulatory subunit of protein kinase A (PRKAR1A) gene; p...
