PURPOSE: To assess the efficacy, safety, and outcome of image-guided high-dose-rate (HDR) brachytherapy in patients with adrenal gland metastases (AGM). MATERIALS AND METHODS: From January 2007 to April 2014, 37 patients (7 female, 30 male; mean age 66.8 years, range 41.5-82.5 years) with AGM from different primary tumors were treated with CT-guided HDR interstitial brachytherapy (iBT). Primary endpoint was local tumor control (LTC). Secondary endpoints were time to untreatable progression (TTUP), time to progression (TTP), overall survival (OS), and safety...

Pheochromocytomas and paragangliomas are rare neuroendocrine tumors known to produce and secrete high levels of circulating catecholamines and their metabolites. The biochemical characteristics of these tumors can be used to divide them into three major phenotypes. The adrenergic phenotype comprises of tumors with predominant elevations in epinephrine and metanephrine levels whereas the noradrenergic phenotype is composed of tumors with predominant elevations in norepinephrine and normetanephrine levels. The dopaminergic phenotype is a third rare group composed of tumors mainly secreting dopamine and 3-methoxytyramine...

BACKGROUND: Pentraxin 3 (PTX3) is an acute-phase glycoprotein, which is increased in patients with cardiovascular disease (CVD) and considered as a predictor of CVD in the general population. Both functional and nonfunctional adrenal tumors are associated with a higher risk of cardiovascular events and mortality. We aimed to investigate plasma PTX3 levels in patients with functioning and nonfunctioning adrenal tumors and to determine its relationship with cardiovascular risk factors. MATERIAL AND METHODS: Twenty-one patients with functional adrenal tumors (11 pheochromocytomas, 9 Cushing's Syndrome and 1 primary hyperaldosteronism), 28 patients with non-functional adrenal incidentilomas, and 40 healthy controls were enrolled in the study...

BACKGROUND: Pheochromocytoma (PHEO) is a rare tumor of the adrenal medulla and sympathetic ganglion that produces the catecholamines norepinephrine and epinephrine. Traditionally, approximately 10% of PHEOs were thought to be malignant, but recent developments in PHEO research have noted that specific genetic mutations are associated with higher risk of metastatic spread. CASE REPORT: We report the case of a 71-year-old female who presented with abdominal pain in September 2009 when she was 64 years old...

Multiple endocrine neoplasia type 1 (MEN1) syndrome is a relatively rare disease, characterized by the occurrence of multiple endocrine tumors in the parathyroid and pituitary glands as well as the pancreas. Here, we report a case of MEN1 with neuroendocrine tumors (NETs) in the stomach, duodenum, and pancreas. A 53-year-old man visited our hospital to manage gastric NET. Five years prior to his visit, he had undergone surgery for incidental meningioma. His brother had pancreatic nodules and a history of surgery for adrenal adenoma...

Growing evidence suggests a major role for Src-homology-2-domain-containing phosphatase 2 (SHP2/PTPN11) in MYCN-driven high-risk neuroblastoma, although biologic confirmation and a plausible mechanism for this contribution are lacking. Using a zebrafish model of MYCN-overexpressing neuroblastoma, we demonstrate that mutant ptpn11 expression in the adrenal gland analog of MYCN transgenic fish promotes the proliferation of hyperplastic neuroblasts, accelerates neuroblastomagenesis, and increases tumor penetrance...

A three-month-old female infant presented with abdominal distention for 2 months. A large palpable mass in right upper quadrant was noted on physical exam. Abdominal ultrasound revealed a large heterogeneous mass with multiple cystic components. Mass was surgically excised and pathology was consistent with mature adrenal teratoma. Teratoma is a germ cell tumor mainly found in gonadal tissues. Occurrence of adrenal gland teratoma in children is very rare with less than 10 pediatric case reports in English literature...

BACKGROUND: Extra-adrenal paragangliomas (PGLs) are infrequent, benign, and neuroendocrine tumors arising from chromaffin cells of the autonomic nervous system. Most PGLs are sporadic, but up to 32% are associated with inherited syndromes such as neurofibromatosis type 1, von Hippel-Lindau disease, and familial PGL. Although most PGLs develop above the umbilicus, they have been reported in the genitourinary (GU) tract. Owing to the paucity of literature on the rates of GU PGL, the objective of our study is to describe the demographic, pathologic, and clinical characteristics of GU PGL, and compare them to non-GU sites of PGL using the surveillance, epidemiology, and end results (SEER) database...

OBJECTIVE: To evaluate differences in clinical and radiologic features of small and large pheochromocytomas. MATERIALS AND METHODS: This study included 39 patients with adrenal pheochromocytomas. Several clinical and radiologic features were statistically analyzed and compared between small and large pheochromocytomas. RESULTS: No significant differences were found in clinical features between them. Small pheochromocytomas had more relatively homogeneous attenuation although large pheochromocytomas had more cystic or necrotic changes...

Context: Pheochromocytomas and paragangliomas (PPGLs) in children are often hereditary and may present with different characteristics compared to adults. Hereditary PPGLs can be separated into two groups: cluster 1 and cluster 2 tumors due to mutations impacting hypoxia and kinase receptor signaling pathways respectively. Objective: To identify differences in presentation of PPGLs between children and adults. Design: A retrospective cross-sectional clinical study...

A 69-year-old man presented with back pain over the prior few months and was hospitalized because of bilateral adrenal masses and fracture of the left sixth rib. The mass on the right measured 6.5×3.6×7.0 cm, that on the left 8.1×4.8×6.9 cm, on CT. The final diagnosis was CD5- and CD10-positive primary adrenal diffuse large B-cell lymphoma (PA-DLBCL) with rib involvement. After EPOCH therapy accompanied with rituximab and intrathecal treatment, the tumors decreased dramatically. However, he died due to disease progression 8 months after the diagnosis...

A 55-year-old man was transported to our hospital after a sudden onset of left lower abdominal pain while driving. Computed tomography (CT) of the abdominal region revealed an extensive iso-intense signal region that had a maximum area of 14×15 cm, which we treated conservatively. A series of follow-up CT images showed the gradual decrease of the left peritoneal mass, while continuity with the left adrenal gland became apparent. He was diagnosed with idiopathic adrenal hemorrhage. Adrenal hemorrhage presenting with huge retroperitoneal tumors is rare, and most cases are treated surgically...

A 63-year-old Japanese woman with an adrenal tumor was transferred to our hospital due to cardiogenic shock. Right and left ventriculography showed severe hypokinesis of the middle segment and the apex in both ventricles, and an endomyocardial biopsy demonstrated a small number of necrotic myocytes and cellular infiltration. She was diagnosed with pheochromocytoma and quickly recovered after treatment with an α-blocker. The functional disability of both the right and left ventricles with less myocardial damage due to an excessive level of catecholamine seemed to be related to the early recovery the present patient with catecholamine-induced cardiomyopathy due to pheochromocytoma...

F-FDOPA is a well-established tool to explore pheochromocytomas. It tends to replace I-MIBG scan in metastatic pheochromocytomas, multiple endocrine neoplasia type 2-related tumors, succinate dehydrogenase [ubiquinone] iron-sulfur subunit-negative tumors, and succinate dehydrogenase[ZERO WIDTH SPACE]-positive lesions. To our knowledge, no study has characterized physiological and pathological adrenal glands with F-FDOPA from a quantitative point of view. We report the features of different normal and pathological adrenal glands with F-FDOPA...

CASE REPORT: A 71-year-old male with acute exacerbation of chronic bronchitis was treated in summer of 2015. The CT scan has revealed a mass on the right side of 11th thoracic vertebra in the adipose tissue with a sharp edge towards the lung and containing a small amount of contrast agent. The radiologist recommended histological sampling of the mass. The tumor was removed by Video-Assisted Thoracic Surgery (VATS) in August of 2015. The patient was discharged on the fifth postoperative day without complication...

The adrenal primary epithelioid angiosarcoma (ASE) is a rare malignant tumor which can be histologically confused with other neoplasms. We report one case in a 79-year-old man who underwent adrenal tumor surgery for a mass fortuitly discovered by imaging for examination of an inflammatory syndrome associated with anemia. The histological diagnosis was difficult because of the undifferentiated and epithelioid appearance of tumor cells, whose immunohistochemical epithelial markers positivity led to frequent confusion with a metastatic carcinoma...

Von Hippel-Lindau syndrome (VHLS) is an autosomal dominant hereditary familial disorder characterized by development of malignant and benign neoplasms. Differential diagnosis of the adrenal and pancreatic masses are difficult in patients with VHLS. Iodine-123 metaiodobenzylguanidine (I-123 MIBG) and indium-111 somatostatin receptor scintigraphies (In-111 SRS) have important roles in the differential diagnosis of adrenal and pancreatic masses in those patients. In this case report, we present the findings of I-123 MIBG single-photon emission computerized tomography (SPECT/CT) and In-111 SRS SPECT/CT in three members of a family with VHLS...

Jin-Ho Choi, Han-Wook Yoo
Steroid 21-hydroxylase deficiency is the most prevalent form of congenital adrenal hyperplasia (CAH), accounting for approximately 95% of cases. With the advent of newborn screening and hormone replacement therapy, most children with CAH survive into adulthood. Adolescents and adults with CAH experience a number of complications, including short stature, obesity, infertility, tumor, osteoporosis, and reduced quality of life. Transition from pediatric to adult care and management of long-term complications are challenging for both patients and health-care providers...

INTRODUCTION: Composite pheochromocytoma is a rare tumor of the adrenal medulla composed of pheochromocytoma and neuroblastic tumor. We report the case of a composite pheochromocytoma detected in a patient with neurofibromatosis type 1. CASE REPORT: A 61-year-old male patient presented occasional sweats with palpitation and moderate high blood pressure. Urinary catecholamine level was increased. CT scan showed a heterogeneous tumor limited to the adrenal gland. Histologically, the tumor showed two components: pheochromocytoma and ganglioneuroma and was diagnosed as a composite pheochromocytoma...
