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...

Introduction: Hormonal syndromes are significant cause of morbidity in patients with neuroendocrine tumors (NET), requiring special treatment, rarely completely efficient. Effect on mortality is also presumed. Our aim was to investigate epidemiological characteristics of NET with hormonal production in our group of patients.Patients and methods: We analyzed 822 patients with NET of various primary tumor sites, treated at our department during period of 2...

IntroductionHypogonadism is a potential manifestation of many chronic diseases including cancer, presumably related to their severity. Since novel anti-cancer treatments have significantly increased survival rates of affected patients, issue of hypogonadism becomes more significant, given the importance of issues like quality of life and potential for reproduction. The aim of our study was to analyze gonadal axis function in male patients with neuroendoc...

Introduction: The majority of adrenocortical incidentalomas (AIs) are nonfunctional adenomas. Some of them demonstrate an autonomous cortisol secretion (ACS), a pathologic condition defined as biochemical evidence of hypercortisolism without typical signs or symptoms of Cushing’s syndrome.Subjects and methods: In this cross-sectional study, we evaluated 152 consecutive patients, aged 58.3 years (range, 25-84 years) of whom 105 (69.1%) with unilatera...

Introduction: Multiple endocrine neoplasia type 2 is an autosomal dominant polyglandular cancer syndrome. It arises as a result of a germline mutation of the RET proto-oncogene. The aim of this study was to evaluate the aggressiveness of medullary thyroid carcinoma (MTC) in patients with a proven germline mutation in codon 634 RET proto-oncogene, the occurrence of other associated diseases and survival analysis.Methods: The retrospectiv...

For the diagnosis of hyperinsulinemic hypoglycemia (HH), it is necessary that in symptomatic hypoglycemia in the fasting test the insulin/glucose ratio is >0.3, or that in spontaneous hypoglycemia there are C-peptide >0.6 nmol/l and insulin >3.0 mIU/ml. It is a well-known fact about the increasing frequency of hypoglycemia after bariatric surgery (estimated up to 30% of patients), mostly within the Dumping syndrome, but the frequency of occurrence of noninsulinoma ...

Introduction: Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy among women during reproductive age. PCOS cardinal manifestations include hyperandrogenism, oligo/anovulation, and/or polycystic ovarian morphology, and is closely linked to metabolic disorders such as obesity and insulin resistance (IR). It was observed that single-point insulin sensitivity estimator (SPISE) index is associated with metabolic abnormalities and could predict glucose regulation ...

Introduction: Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy among women during reproductive age. Using ESHRE/ASRM diagnosis of PCOS is considered when 2 of 3 criteria are present: polycystic ovary morphology (PCOM), oligo/anovulation (ANOV) and hyperandrogenism (HA). These criteria form four different phenotypes: A (ANOV, HA, PCOM), B (ANOV, HA), C (HA, PCOM) and D (ANOV, PCOM). Several studies have found differences in anthropometric, hormonal and meta...

Introduction: Polycystic ovarian syndrome (PCOS) is characterized by hyperandrogenism, chronic oligo-/anovulation and polycystic ovarian morphology. Hyperandrogenism is a key diagnostic feature of PCOS and according to ESHRE/ASRM criteria it can be clinical and/or biochemical. SPISE index (single-point insulin sensitivity estimator index) is a new indicator of insulin sensitivity and a predictor of abnormal glucose metabolism. The aim of the research was to analyse association...
