Introduction: Cortisol has important roles in the regulation of body composition and hypercortisolaemia have major impact on body fat distribution. The aim of this study was to analyze differences in adipose tissue distribution in women with Cushing’s disease and Cushing’s syndrome due to adrenal adenoma.Method: We evaluated 12 women with Cushing’s syndrome, six with ACTH secreting pituitary adenomas (Group A) and six with adrenal adenomas...

Introduction: Luteinizning hormone (LH/hCG) responsiveness has been documented in both normal and pathological adrenal glands, but it is unclear whether chronic exposure to LH could affect adrenal function by increasing LH receptor (LHR) expression.Subjects and methods: We studied 12 postmenopausal women with previously documented adrenal tumor. All patients underwent standard hormonal testing for assessment of tumor functionality. Then hCG test was perf...

Adrenocortical carcinoma (ACC) is rare malignancy associated with poor prognosis. The aim of this study was to present clinical characteristics and survival of patients with ACC and to analyse the effect of prognostic factors on survival.We retrospectively analysed 69 patients (46 female and 23 males) with pathologically confirmed ACC who were treated in our hospital between January 2005 and December 2015. The median age at diagnosis was 51,0 years (rang...

The clear cell renal cell carcinoma (ccRCC) can be sporadic or familiar, with the mutated von Hippel-Lindau (VHL) gene. The inactive VHL protein prevents degradation of hypoxia inducible factor (HIF) that promotes overexpression of angiogenic factors such as vascular endothelial growth factor (VEGF) and erythropoietin (EPO). Sequencing and multiplex ligation-dependent probe amplification (MLPA) of VHL gene in 43 samples of ccRCC in tumors vs surrounding healthy tissues reveale...

Ghrelin is a somatotrophic, orexigenic and adipogenic hormone that has an important homeostatic role by linking regulatory systems for growth and energy balance. Ghrelin- secreting neuroendocrine tumors are rare, but we had the opportunity to study a 71 years old female patient with a gastric ghrelinoma. The patient was submitted to gastroenterological examination after having episodes of diarrhea, and small subepithelial polyp (5 mm) was revealed on gastroscopy. Pathohystolog...

Cortisol rise during pregnancy is connected with fetal maturation. Together with the increase of insulin resistance it might have a role in allocation of nutrients between mother and fetus. Cortisol and insulin secretion during pregnancy seems to be induced by fluctuations in BMR. Here, we try to identify relationship between BMR and secretion of cortisol and insulin during pregnancy.In 25 healthy women (age range 20–39 years; mean±S.D.<...

Background: Ret protooncogene germ-line mutations are associated with the inherited multiple endocrine neoplasia type 2 syndromes (MEN2a and MEN2b) and also with familial medullary thyroid carcinoma (FMTC). In this study, we report a large scale of mutations in exon 10, 11, 13 and 14 RET protoocogene in patients from Serbia. Our study included patients with MTC.Methods: Our study included 180 patients. Patients were tested for RET protooncogene mutations...

Background: Several polymorphisms of glucocorticoid receptor (GR) gene, including BclI, N363S and ER22/23EK, which may have an influence on glucocorticoid sensitivity, have been reported. BclI and N363S polymorphisms have been associated with clinical characteristics of increased and ER22/23EK of decreased glucocorticoid (GC) effects. On the other hand, metabolic syndrome has been described in patients with adrenal incidentalomas.Objective ...

A 34 year-old female patient was admitted to the hospital because of a large nodule in the left thyroid lobe and elevated calcitonine level. A large encapsulated tumor was found and total thyroidectomy with left neck dissection was performed. Pathohistology revealed medullary and papillary carcinoma separate from each other in tumor tissue but mixed in regional lymph nodes. Papillary component was dominant in thyroid tissue but not in lymph nodes. Both calcitonine and thyroglo...

Neuroendocrine tumours (NETs) have a unique ability to produce and secrete a variety of biogen amines and peptide hormones. They arise from multipotential stem cells, which differentiate during tumorigenesis into specific cell lines. Some of these tumours are functional, producing characteristic clinical syndromes. We present a female patient incidentally discovered to have diffuse liver metastases of neuroendocrine tumour of unknown primary origin. She was free of symptoms at...
