Oncocytic tumors arising from the adrenal gland are rare. Oncocytic adrenal neoplasms (OAN) may mimic adrenocortical carcinoma (ACC) at presentation, and can only be definitively diagnosed histologically. Most OANs are benign, and carry a favorable prognosis. We report on an 83-year-old female who, while being investigated for anemia and weight loss, was found to have a 23 cm adrenal mass concerning for ACC. Adrenalectomy and histopathology confirmed a malignant OAN, based on the Lin-Weiss-Bisceglia criteria...

During the last decade, there has been an increasing interest in the coupling between the acute inflammatory response and the Hypothalamic-Pituitary-Adrenal (HPA) axis. The inflammatory response is activated acutely by pathogen- or damage-related molecular patterns, whereas the HPA axis maintains a long-term level of the stress hormone cortisol which is also anti-inflammatory. A new integrated model of the interaction between these two subsystems of the inflammatory system is proposed and coined the integrated inflammatory stress (ITIS) model...

Despite recent comprehensive genetic analyses, molecular evidence for a pathophysiological continuum linking benign adrenocortical adenoma (ACA) and highly aggressive adrenocortical carcinoma (ACC) is still elusive. Using human tumor samples and the established ACC cell line SW-13, this study investigated potential regulatory roles for FOXO transcription factors, in modulating adrenocortical tumorigenesis. Adrenocortical tumor specimens (20 ACAs, 10 ACCs, and 9 normal adrenal tissue samples) obtained from 30 patients were analyzed for ubiquitously expressed FOXO transcription factors, FOXO1 and FOXO3 using qRT-PCR and immunohistochemistry...

OBJECTIVE: Cushing syndrome (CS) is a constellation of clinical signs and symptoms resulting from chronic exposure to excess cortisol, either exogenous or endogenous. Exogenous CS is most commonly caused by administration of glucocorticoids. Endogenous CS is subdivided into two types: adrenocorticotropic hormone (ACTH) dependent and ACTH independent. CONCLUSION: Cushing disease, which is caused by a pituitary adenoma, is the most common cause of ACTH-dependent CS for which pituitary MRI can be diagnostic, with bilateral inferior petrosal sinus sampling useful in equivocal cases...

REVIEW
Peyman Björklund, Samuel Backman
Pheochromocytomas and paragangliomas (PPGLs) are neuroendocrine tumors arising in the medullae of the adrenal glands or in paraganglia. The knowledge of the tumor biology of these lesions has increased dramatically during the past two decades and more than a dozen recurrently mutated genes have been identified. Different clusters have been described that share epigenetic signatures. Mutations in the succinate dehydrogenase complex subunit genes play a pivotal role in reprogramming the epigenetic state of these tumors by inhibiting epigenetic regulators such as TET enzymes and histone demethylases...

We report a surgical case of retroperitoneal paraganglioma. A paraganglioma is a catecholamine-producing tumor originating in the chromaffin cells of the sympathetic ganglion. It is a kind of pheochromocytoma which occurs on the outside of the adrenal gland. The patient was a 72 year old male with a history of hypertension and a pacemaker implantation. A mass in the ventral side of the right iliopsoas muscle was detected during a routine contrasting computed tomography (CT) examination for checking his pacemaker...

The patient was a 76-year-old man. Because bilateral adrenal tumor (right adrenal gland 7 cm, left adrenal gland 1.5 cm) was detected in by computed tomography (CT) in methotrexate (MTX) administration for articular rheumatism from 2011, he was referred to this hospital in February, 2016. An endocrine examination, and imaging study did not lead to a definitive diagnosis and CT-guided lower needle biopsy was performed. The pathological diagnosis was diffuse large B cell lymphoma. Also, in situ hybridization revealed EBER-positive and the diagnosis of MTX-related lymphoproliferative disease (MTXLPD) was made in conjunction with the medical history...

The terms composite and collision tumors have been used interchangeably throughout radiological literature. Both composite and collision tumors involve two morphologically and immunohistochemically distinct neoplasms coexisting within a single organ. However, collision tumors lack the histological cellular intermingling seen in composite tumors. Composite tumors often arise from a common driver mutation that induces a divergent histology from a common neoplastic source while collision tumors may arise from coincidental neoplastic change...

Cushing syndrome (CS) is caused by chronic exposure to excess glucocorticoids. Early recognition and treatment of hypercortisolemia can lead to decreased morbidity and mortality. The diagnosis of CS and thereafter, establishing the cause can often be difficult, especially in patients with mild and cyclic hypercortisolism. Surgical excision of the cause of excess glucocorticoids is the optimal treatment for CS. Medical therapy (steroidogenesis inhibitors, medications that decrease adrenocorticotropic hormone [ACTH] levels or glucocorticoid antagonists) and pituitary radiotherapy may be needed as adjunctive treatment modalities in patients with residual, recurrent or metastatic disease, in preparation for surgery, or when surgery is contraindicated...

A concerted effort has been made in the past decade to better differentiate benign from malignant adrenocortical tumors. Of those tumors found to be adrenocortical carcinomas (ACCs) and through the use of multiple modalities including biochemical, radiologic, and genomic analysis, significant strides have been made in understanding what drives ACC development, how various treatments may result in different outcomes, which ACCs are more likely to respond to various treatments, and overall prognosis. While most patients will have recurrence of their ACC and succumb to their disease, the disease course is highly variable; it is therefore imperative that each patient is treated with individualized attention paid to their particular ACC...

Posterior retroperitoneoscopic adrenalectomy has recently increased in popularity and currently adopted in about 20% of referral centers. It may provide more direct access to the adrenals, thus avoiding post-operative adhesions and the need for patient repositioning in bilateral adrenalectomy. Although it has been suggested to be feasible for large tumors, large tumor size is indicated as the main limitation of PRA, mainly because of the small space available for dissection.

BACKGROUND: Ganglioneuroma (GN) is a rare benign tumor arising from the neural crest cells. The reported incidence of GN is one per million population. As a primary retroperitoneal tumor, it constitutes only a small percentage of 0.72 to 1.6%. GN can arise de novo or as a result of maturation of a neuroblastoma either spontaneously or after chemotherapy. The most common location is the posterior paraspinal mediastinum, retroperitoneum, neck and adrenal gland. However, GN can potentially occur anywhere along the peripheral autonomic ganglion sites...

Aldosterone-producing adenomas (APAs) are benign tumors of the adrenal gland that constitutively produce the salt-retaining steroid hormone aldosterone and cause millions of cases of severe hypertension worldwide. Either of 2 somatic mutations in the potassium channel KCNJ5 (G151R and L168R, hereafter referred to as KCNJ5MUT) in adrenocortical cells account for half of APAs worldwide. These mutations alter channel selectivity to allow abnormal Na+ conductance, resulting in membrane depolarization, calcium influx, aldosterone production, and cell proliferation...

Pheochromocytoma is a kind of rare tumor, occurring at any site in the sympathoadrenal system. Main lesions occur within the adrenal gland; only 1%-2% occur within the chest, and most of these are located in the posterior mediastinum. Intrapericardial pheochromocytoma is extremely rare in clinic, only about 100 cases have been reported in total in both the domestic and foreignliterature since Besterman et al. first reported in 1974. It is often difficult to diagnose and locate these tumors. Hence, we present here a case of adrenal combined with heart multiple pheochromocytomas and discuss about techniques contributed to diagnosis and localization...

Thyroid transcription factor-1 (TTF-1) is a specific and sensitive marker for canine pulmonary tumors but is also expressed in thyroid carcinomas, which commonly metastasize to lung. Napsin A and surfactant protein A (SP-A) are used in the histologic diagnosis of non-small-cell lung cancer in humans but have not been thoroughly evaluated in neoplasms of dogs. The objective of this study was to compare the efficacy of immunohistochemistry for SP-A, napsin A, and TTF-1 in the diagnosis of canine pulmonary carcinomas...
