A 71-year-old female presented with melena and anemia. She had a past medical history of renal cell carcinoma diagnosed six years earlier and treated with left nephrectomy. Gastroscopy and colonoscopy showed no abnormalities. Renal cell carcinoma (RCC) is the third commonest urological malignancy, and approximately 25-50% of patients develop metastatic disease after surgery of the primary tumor. The most common sites of metastasis involve lung, lymph nodes, liver, bone and adrenal glands.

Insulinoma is a rare, usually benign, pancreatic neuroendocrine tumor. The clinical features of an insulinoma are fasting hypoglycemia with neuroglycopenic symptoms including confusion and unusual behavior, while hypertension is usually not associated with the disease. We herein report a patient with insulinoma who manifested paroxysmal hypertension and neuroglycopenic symptoms. The possible etiology of hypertension induced by an insulinoma is catecholamine release in response to hypoglycemia, which may cause acute hypertension through activation of the sympatho-adrenal system...

Hepatocellular carcinoma (HCC) occurs more frequently and aggressively in men than women, but the mechanistic basis of this gender disparity is obscure. Chronic inflammation is a major etiological factor in HCC, so we investigated the role of cortisol in gender discrepancy in a zebrafish model of HCC. Inducible expression of oncogenic KrasV12 in hepatocytes of transgenic zebrafish resulted in accelerated liver tumor progression in males. These tumors were more heavily infiltrated with tumor-associated neutrophils (TAN) and macrophages (TAM) versus females, and they both showed pro-tumor gene expression and promoted tumor progression...

INTRODUCTION: Adrenal corticomedullary adenoma was reviewed in many cases in PubMed Library, While the coincidence corticomedullary adrenal carcinoma in the same gland was just described in two cases in the medical literature. Our case is the third to be reported and was treated with surgery and adjuvant chemotherapy and followed for two years. PRESENTATION OF CASE: A 50-year-old man suffered from a mass effect in the left abdominal side. While the laboratory showed a mild elevation in the levels of both serum cortisol and 24h urine cortisol, radiological images were highly suggested an adrenal malignant tumor without metastasis...

Pheochromocytomas and extra-adrenal paragangliomas are catecholamine-secreting tumors that rarely occur in pregnancy. The diagnosis of these tumors in pregnancy can be challenging given that many of the signs and symptoms are commonly attributed to preeclampsia or other more common diagnoses. Early diagnosis and appropriate management are essential in optimizing maternal and fetal outcomes. We report a rare case of a catecholamine-secreting tumor in which diagnosis occurring at the time labor was being induced for concomitant preeclampsia with severe features...

Neuroendocrine tumors which have the potential to secrete catecholamines are either associated with sympathetic adrenal (pheochromocytoma) or nonadrenal (paraganglioma) tissue. Surgical removal of these tumors is always indicated to cure and prevent cardiovascular and other organ system complications associated with catecholamine excess. Some of these tumors have malignant potential as well. The diagnosis, localization and anatomical delineation of these tumors involve measurement of catecholamines and their metabolic end products in plasma and urine, (123)I-metaiodobenzylguanidine scintigraphy, computed tomography, and/or magnetic resonance imaging...

Paragangliomas/pheochromocytomas comprise rare tumors that arise from the extra-adrenal paraganglia, with an incidence of about 2 to 8 per million people each year. Approximately 40% of cases are due to genetic mutations in at least one out of more than 30 causative genes. About 25-30% of pheochromocytomas/paragangliomas develop under the conditions of a hereditary tumor syndrome a third of which are caused by mutations in the VHL gene. Together, the gene mutations in this disorder have implicated multiple processes including signaling pathways, translation initiation, hypoxia regulation, protein synthesis, differentiation, survival, proliferation, and cell growth...

Endogenous hypercortisolism (Cushing syndrome) usually implies the presence of a pathologic condition caused by either an ACTH-secreting neoplasm or autonomous cortisol secretion from a benign or malignant adrenal neoplasm. However, sustained or intermittent hypercortisolism may also accompany many medical disorders that stimulate physiologic/non-neoplastic activation of the HPA axis (formerly known as pseudo-Cushing syndrome); these two entities may share indistinguishable clinical and biochemical features...

Tail gut cysts are rare congenital lesions developing from postanal primitive gut remnants. They are mostly benign but carry a potential of malignant transformation, such as adenocarcinoma, neuroendocrine tumor, adenosquamous carcinoma, and pseudomyxoma peritonei. We present a 39-year-old woman with a neuroendocrine tumor arising within a tail gut cyst. She underwent complete resection in 2011. After 4 years, she was admitted with breast nodules, left proptosis, and gaze difficulties. Ga-DOTATATE PET/CT demonstrated extensive metastases including pelvic, lymph node, adrenal gland, bone, retro-orbital, cardiac, breast, skin, and subcutaneous metastases...

Eag1 (ether-à-go-go-1), a member of the voltage-dependent potassium channel family, is expressed mainly in the brain, and at low levels in placenta, testis, and adrenal gland, and only transiently in myoblasts. Recently, several studies have suggested that Eag1 is selectively expressed in various tumor tissues. Eag1 plays important roles in tumor proliferation, malignant transformation, invasion, metastasis, recurrence, and prognosis. Therefore, it has become a new molecular target for tumor diagnosis, prognosis evaluation, and tumor-targeted therapy...

INTRODUCTION: Laparoendoscopic single-site surgery is a recently innovated urologic surgical procedure. Transumbilical laparoendoscopic single-site adrenalectomy (LESS-A) is technically safe and feasible in patients with benign adrenal tumors. To improve patient counseling and informed consent, we evaluated patient-reported postoperative pain, body image, and cosmetic satisfaction after transumbilical LESS-A. METHODS: We reviewed 24 patients who underwent transumbilical LESS-A and assessed their operative and esthetic outcomes and incisional pain...

Kidney ultrasound is one of the basic procedures in the practice of a urologist. Apart from the location and the size, description of renal morphology should contain the thickness of the anterior lip parenchyma in a transverse section and the location of possible narrowings. Uneven outline of the kidney is a sign of past inflammatory conditions. In the case of the pelvicalyceal system dilation, it is advised to specify the dimensions of the pelvis and calyces. Convex shape of the calyces proves elevated pressure within the pelvicalyceal system...

A varicocele is described as pathologically enlarged, tortuous veins of the pampiniform plexus, leading to an increased testicular temperature and adrenal metabolite reflux into the testes. Varicocele can impair spermatogenesis and is considered to be the most common cause of male infertility. Patients may palpate a thickening in the scrotum or complain of dull scrotal or inguinal pain, which increases when standing or during erection. In the case of a sudden onset of varicocele in elderly men, it is necessary to exclude renal tumor and extend diagnostic ultrasound with the assessment of the abdominal cavity...

F-FDG PET/CT was performed to detect an occult malignancy in a 26-year-old woman with complicated medical history which included paroxysmal hypertension and significantly elevated tumor marker. The images revealed lesions in the thyroid, lymph nodes, and bilateral adrenal glands. Further I-MIBG SPECT/CT revealed intense activity in the lesion in the left adrenal gland, which was consistent with pheochromocytoma. The pathology examination after subsequent neck biopsy demonstrated medullary thyroid carcinoma...

Pancreatic metastasis of colorectal cancer is uncommon and is often identified in later stages of cancer, thereby making resection more uncommon. We report a case oflong -term survival after resection of metachronous metastasis to the pancreas from primary sigmoid colon cancer. A 50-year-old female patient underwent a sigmoid colon resection and bilateral salpingo-oophorectomy for sigmoid colon cancer and metastatic ovarian cancer in 2007. She underwent partial lung resection for metastatic lung cancer twice...
