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...

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...

Acne is a common, worldwide problem that is usually multifactorial in etiology, but androgens may play a pivotal role in the development and severity of acne. Endocrinopathies, such as polycystic ovarian syndrome, ovarian tumors, or adrenal hyperplasia or tumors, may be detected in some patients with acne, especially if acne is sudden in onset, associated with hirsutism or menstrual irregularities, or associated with cushingoid facies, acanthosis nigricans, patterned hair loss, or deepened voice. In these instances, serum-free and total testosterone, dehydroepiandrosterone, luteinizing hormone, and follicle stimulating hormone should be tested...

Primary retroperitoneal teratomas are uncommon extragonadal nonseminomatous germ cell tumors that are composed of well differentiated parenchymal tissues which are derived from more than one of the three embryonic germ cell layers. Here we report an unusual and first of its kind, a case of primary mature cystic retroperitoneal teratoma mimicking as adrenal tumor in a 7-month-old female in which the tumor was predominantly composed of neurogenic tissue histologically which is unlike the usual pattern seen in the teratomas...

Laparoscopic adrenalectomy became the gold standard for adrenal disease, from incidentaloma to cancer. Partial adrenalectomy is difficult to accept due to its technical difficulties as well as hemorrhagic risk and a consensus has not been reached. On the other hand, in selected cases of benign adrenal tumors, adrenalectomy may be futile, partial resections being perfectly justified and with lower hemorrhagic risks. For functioning tumors smaller than 3 cm with an anterior or lateral location, partial adrenalectomy may be indicated...

Myelolipomas represent 3-7% fromthe primary tumors of the adrenal gland. Most often they are incidental findings. In most cases are asymptomatic, rarely they present symptoms (pain, abdominal discomfort, hematuria or signs of internal hemorrhage). Histologically benign, this variety of tumor requires only local excision, in symptomatic forms. Their dimensions are generally up to 4-5 cm, so the laparoscopic approach seems the most appropriate. We present the case of a 65 years old patient, electively operated for a right adrenal tumor formation...

Some testosterone-producing adrenal tumors can be successfully treated with long-acting GnRH analogs and adrenal venous sampling can be useful to detect rare ectopic sex steroid-producing tumors or confirm bilateral adrenal androgen hyperproduction in female hyperandrogenism.

Paragangliomas are rare extra-adrenal tumors of sympathetic or parasympathetic paraganglia origin; of these, mediastinal paragangliomas are 2% of all cases. We present the case of a 21-year-old woman with uncontrolled arterial hypertension who had a functioning 6.5 × 6.2-cm retrocardiac paraganglioma firmly attached to the pericardium. The patient underwent tumor resection via a right thoracoabdominal incision; this surgical approach enabled adequate exposure for complete resection without institution of cardiopulmonary bypass or need for cardiac reconstruction or autotransplantation...

PET/CT was performed on an asymptomatic 62-year-old woman with a suspected adrenal mass and revealed the lesion with high F-FDG avidity and inferior vena cava involvement. A malignant nonfunctioning adrenal tumor was suspected. However, histopathology of the resected lesion revealed a leiomyoma arising from the inferior vena cava.

Paragangliomas are rare neoplasms that arise from neural crest cells of the autonomous system. Herein, we present a case of a 37-year-old patient with a history of retroperitoneal paraganglioma and tuberculous infection presenting with a paraganglioma of the neck that was initially misdiagnosed as metastatic tumor originating from the lungs. Cytological features from fine needle aspiration and immunocytochemistry pointed to the right diagnosis. However, distinguishing between primary and metastatic site of a paraganglioma can be very challenging due to the overlapping features of these entities...

The inhibin-α gene was identified as a tumor suppressor gene in the gonads and adrenal glands by functional studies using knockout mice. Methylation of CpG sites within the regulatory regions of tumor suppressor gene is frequently associated with their transcriptional silencing. We investigated epigenetic modifications, changes in loss of heterozygosity (LOH), and mutation of the inhibin-α gene, and regulation of transcriptional expression in response to inhibitors of DNA methylation (5-aza-2'-deoxycytidine, 5-AzaC) in human lymphoid (Jurkat, Molt-4, Raji, and IM-9) and myeloid (HL-60, Kasumi-1, and K562) leukemia cells...

Carcinomas arising from embryonic adrenal rests are rare with only a handful of reported cases. We report a case of an adrenocortical carcinoma arising from an adrenal rest located between the bladder and prostate in a 51 year-old man. The patient presented following a year of rectal pain and constipation. Computed tomography (CT) scan revealed a 9 cm pelvic mass that appeared to arise from the soft tissue between the bladder and prostate, with displacement of the organs and narrowing of the rectal lumen, suspected to be a sarcoma...

Neuroblastoma is an embryonal tumor of the sympathetic nervous system, arising during fetal or early post-natal life from sympathetic cells derived from the neural crest. A 9-day-old boy was diagnosed as adrenal neuroblastoma with liver metastasis by biopsy. After 6 years of follow-up with ultrasound observation, the boy presents a process of spontaneous recovery without any special treatment. Spontaneous regression of cancer is defined as the decrease in size or disappearance of a primary tumor or metastatic disease without therapeutic intervention...

BACKGROUND: Dysregulated WNT signaling dominates adrenocortical malignancies. This study investigates whether silencing of the WNT negative regulator DKK3 (Dickkopf-related protein 3), an implicated adrenocortical differentiation marker and an established tumor suppressor in multiple cancers, allows dedifferentiation of the adrenal cortex. METHODS: We analyzed the expression and regulation of DKK3 in human adrenocortical carcinoma (ACC) by qRT-PCR, immunofluorescence, promoter methylation assay, and copy number analysis...

OBJECTIVE: The current study examined whether (a) Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms were associated with dysregulation of stress-related mechanisms, and (b) whether ADHD symptoms interact with affective disorders in their association with dysregulated stress-related mechanisms. METHODS: Data were obtained from 2307 subjects participating in the Netherlands Study of Depression and Anxiety. Stress-related mechanisms were reflected by the following biomarkers: (1) hypothalamic-pituitary-adrenal axis indicators (salivary cortisol awakening curve, evening cortisol, cortisol suppression after a 0...
