Giovanni Taffurelli, Claudio Ricci, Riccardo Casadei, Saverio Selva, Francesco Minni
Open adrenalectomy still plays an important role in adrenal surgery. A review of the current literature has been carried out to discuss the main indication to open adrenalectomy with regards to the main adrenal pathologies. The authors underlined the role of open adrenalectomy on the basis of personal experience and a literature review. Indication to open adrenalectomy for adrenal cysts, myelolipomas, pheochromocytomas, metastases, adrenocortical carcinomas and tumour recurrences were analysed and discussed...

INTRODUCTION: Birt-Hogg-Dubé syndrome (BHDS) is a rare autosomal dominant genodermatosis characterized by cutaneous fibrofolliculomas and/or trichodiscomas, lung cysts, spontaneous pneumothorax and renal tumors. However, its clinical expression is highly variable. This syndrome is caused by germline mutations in the folliculin gene (FLCN) on chromosome 17p11.2. MAIN OBSERVATIONS: Two men, 60 and 39-year-old, presented with a several year history of asymptomatic whitish papules scattered over the face and neck...

The CABLES1 cell cycle regulator participates in the adrenal-pituitary negative feedback, and its expression is reduced in corticotropinomas, pituitary tumors with a largely unexplained genetic basis. We investigated the presence of CABLES1 mutations/copy number variations (CNVs) and their associated clinical, histopathological and molecular features in patients with Cushing's disease (CD). Samples from 146 pediatric (118 germline DNA only/28 germline and tumor DNA) and 35 adult (tumor DNA) CD patients were screened for CABLES1 mutations...

Abiraterone acetate 1000 mg/day, combined with prednisone 5 mg PO twice daily, is indicated for the treatment of metastatic castration-resistant prostate cancer (mCRPC). Abiraterone acetate is the oral prodrug of abiraterone, a specific CYP17 inhibitor that blocks androgen biosynthesis within the adrenal glands, testes and tumor microenvironment. In a phase III trial of men with asymptomatic or minimally symptomatic, chemotherapy-naïve mCRPC, treatment with oral abiraterone acetate plus prednisone led to a statistically significant improvement in the co-primary endpoints of overall survival and radiographic progression-free survival when compared with placebo plus prednisone...

BACKGROUND: Silent corticotroph adenomas (SCAs) are characterized by strong ACTH immunostaining without clinical manifestations of hypercortisolism. Patients with SCAs often present with mechanical symptoms related to tumor growth. This study investigates the hypothalamic pituitary adrenal axis (HPA) characteristics after adenomectomy in patients with SCAs. METHODS: Biochemical parameters of HPA function were monitored frequently after surgical resection of non-functioning macroadenomas...

Renal angiomyolipomas are the most common renal mesenchymal tumors. While classic angiomyolipomas are benign, there are a number of other subtypes. Epithelioid variants are potentially malignant and may be indistinguishable from renal cell carcinoma on imaging. We present a 52-year-old woman who underwent left nephrectomy for an aggressive-appearing malignant renal epithelioid angiomyolipoma. At 6 months postoperatively, restaging FDG PET/CT demonstrated a hypermetabolic left adrenal mass extending to the left adrenal vein, left renal vein, inferior vena cava, and right atrium (SUVmax = 12)...

Adrenocortical carcinoma (ACC) is a rare and highly aggressive malignant neoplasm which can produce intravascular extension into the inferior vena cava (IVC) rarely extend into the right atrium (RA). We report a case of a male patient with large ACC with extension into the IVC and RA. Computed tomography showed a large right adrenal mass with contiguous tumor thrombus extending into IVC and RA with extension to the level of tricuspid valve. Patient underwent combined cardiac and abdominal surgical intervention on cardiopulmonary bypass with removal of the mass...

Adolescent alcohol use comprises a significant public health concern and is often characterized by binge-like consumption patterns. While ethanol exposure in adulthood has been shown to alter the stress response, including the Hypothalamic-Pituitary-Adrenal (HPA) axis, few studies have examined whether binge-like ethanol exposure during adolescence results in enduring changes in HPA axis sensitivity in adulthood. In the present studies, adolescent Sprague-Dawley rats were given intragastric (i.g.) intubations of ethanol (4 g/kg) or vehicle once per day for three consecutive days, beginning on postnatal day (P) 30 (±1)...

Reninoma is a rare form of secondary hypertension. The present study reported a case of reninoma that coexisted with an adrenal adenoma in a young female with secondary hypertension during pregnancy. The patient, a 31-year-old female exhibiting hypertension for >1 year, developed a mass in the right adrenal gland, which was detected by an ultrasound scan in the 33rd gestational week. In addition, a well-defined solid mass on the left kidney was detected by a magnetic resonance imaging scan1 month subsequent to the termination of the pregnancy...

Von Hippel-Lindau (VHL) disease is an inherited syndrome with autosomal-dominant transmission, characterized by central nervous system and retinal hemangioblastomas, visceral cysts and tumors. Optimal surgical treatment, including its timing, remains a controversial topic. The present study reports the case of a 67-year-old female patient with adrenal and pancreatic manifestations of VHL. A laparoscopic cortex-sparing left adrenalectomy for a 4-cm pheochromocytoma and pancreatic enucleation for pancreatic polypeptidoma of the pancreas tail were performed during the same operative procedure...

Dear Editor, Pheochromocytomas and paragangliomas (PPGL) are rare neuroendocrine tumors arising from the adrenal medulla and extra-adrenal paraganglia, respectively. Forty percent are explained by germline mutations in known susceptibility genes. Furthermore, somatic mutations were identified in an additional 30% of PPGL, mostly in NF1, RET, VHL, MAX, and HRAS. However, screening is limited to a few studies mainly using Sanger sequencing (Burnichon, et al. 2012; Burnichon, et al. 2011; Crona, et al. 2013; Luchetti, et al...

Adrenal masses pose a diagnostic challenge. The differential diagnosis includes functional adrenal tumors, incidentally found adrenal masses, metastases from an unknown primary cancer, and abscesses. Infrequently, adrenal gland abscesses have been reported in disseminated nocardiosis affecting immunocompetent and immunocompromised patients. We report a case of disseminated Nocardia farcinica pneumonia with an adrenal gland abscess in an immunocompetent patient with no identified risk factors for nocardiosis...

BACKGROUND: Adrenal ganglioneuroma (AGN) is a rare tumor that originates from the gangliar cells of the sympathetic nervous system. It represents less than 5% of all adrenal masses. AGN occurs as a large mass, with benign behavior and no relevant symptoms and hormonal secretion, but it is often misdiagnosed because the preoperative radiological diagnosis is generally challenging. The aim of the present paper is to report the experience of a tertiary referral academic center regarding the management of AGN and review the relevant literature...

Germline mutations in SDHB predispose to hereditary paraganglioma syndrome type 4. The risk of developing paraganglioma (PGL) or pheochromocytoma (PHEO) in SDHB mutation carriers is subject of recent debate. In the present nationwide cohort study of SDHB mutation carriers identified by the clinical genetics centers of the Netherlands, we have calculated the penetrance of SDHB associated tumors using a novel maximum likelihood estimator. This estimator addresses ascertainment bias and missing data on pedigree size and structure...

Luteolin [2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-4-chromenone] is an active flavonoid compound from Lonicera japonica (Caprifoliaceae). Luteolin inhibits tumor cell proliferation, inflammatory and oxidative stress better, when compared with other flavonoids. In the present study, it was demonstrated that luteolin induces typical apoptosis in PC12 cells (derived from a pheochromocytoma of the rat adrenal medulla) accompanied by DNA fragmentation and formation of apoptotic bodies. In addition, luteolin regulates expression of the endoplasmic reticulum (ER) chaperone binding immunoglobulin protein, activating ER stress sensors (eukaryotic initiation factor 2α phosphorylation and X‑box binding protein 1 mRNA splicing) and induced autophagy...

Adrenal tumors can vary from a benign adrenocortical adenoma with no hormonal secretion to a secretory adrenocortical malignancy (adrenocortical carcinoma) or a hormone-secreting tumor of the adrenal medulla (pheochromocytoma). Currently, laparoscopic adrenalectomy is regarded as the preferred surgical approach for the management of most adrenal surgical disorders, although there are no prospective randomized trials comparing this technique with open adrenalectomy. However, widespread adoption of robotic technology has positioned robotic adrenalectomy as an option in some medical centers...
