Paragangliomas (PGLs) and pheochromocytomas (PCCs) are rare neuroendocrine tumors that arise from chromaffin cells of the adrenal medulla and the sympathetic/parasympathetic neural ganglia, respectively. We retrospectively analyzed 82 patients (43 female and 38 males) predominantly with PGLs who were hospitalized between January 2002 and December 2022. Twenty one patients were lost to follow up. The median age at diagnosis was 47 years (11–75) and the mean tumor size was ...

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: 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...

Interindividual variations in tissue sensitivity to glucocorticoids (GC) have been partly attributed to polymorphisms in the glucocorticoid receptor (GR) gene. The aim of this study was to investigate whether BclI variant of the GR gene may contribute to metabolic abnormalities frequently present in patients with adrenal incidentaloma (AI). Biochemical tests and hormonal evaluation were performed in 106 consecutive women with AI. Non-diabetic patients underwent an ora...

Neuroendocrine tumors encompass a heterogeneous group of tumors arising from the diffuse neuroendocrine system. The incidence of NETs rises with age, with the peak after 65 years. However, all NETs observed in adults may be diagnosed in children too. There are a very few studies addressing NETs in young patients. This study summarizes clinical, histopatological and genetic characteristics of young patients with NETs. This is a retrospective study describing clinical, histopath...

To investigate the prevalence of SH and osteoporosis in female patients with unilateral AIs (UAIs) and bilateral AIs (BAIs).We enrolled 106 female patients, 68 (64.2%) with UAIs and 47 (35.8%) with BAIs. SH was diagnosed in the presence of serum cortisol levels after 2-day low-dose dexamethasone suppression test (LDDST) >50 nmol/l with at least one of the following parameter (midnight serum cortisol >208 nmol/L, 24-h urinary free cortisol >24...

Interindividual variations in tissue sensitivity to glucocorticoids have been partly attributed to polymorphisms in the glucocorticoid receptor (GR) gene. The aim of this study was to investigate the prevalence of subclinical hypercortisolism (SH) in women with adrenal incidentaloma (AI), and whether BclI variant of the GR gene may contribute to metabolic abnormalities frequently present in these patients. We evaluated 106 women with AI. Anthropometric characteristics...

Introduction: Multiple endocrine neoplasia type 1 (MEN1) is a rare multitumour syndrome, characterized by the occurrence of parathyroid (PHPT), pituitary adenoma (PA) and pancreatic neuroendocrine tumors (pNETs). The gene responsible is MEN1 gene, however 10 to 20% of patients are not carriers of MEN1 mutation. Recently, a study has shown that these patients have less aggressive course of the disease, and more favorable life expectancy than their mutation-pos...
