Pathogenesis of thyroid cancer involves a number of biological, and environmental factors. The growth factors have mitogenic, proliferative and dedifferentiating effects. Some of the cytokines: Vascular Endothelial Growth Factor (VEGF), Fibroblast Growth Factor (FGF), Hepatocyte Growth Factor (HGF) are detected in a neoplasmatic tissue. Moreover, there are affected thyroid cancer cell growth and function in vitro.Aim of the study: The aim of the s...

Incidentalomas of adrenal glands are found in approximately 0.4–4.4% of abdominal CT-scan examinations and some of them can be caused by congenital adrenal hyperplasia (CAH). Bilateral masses can be detected in 10–15% of cases. CAH is one of the most common autosomal recessively inherited disorders. Non-classical form of congenital adrenal hyperplasia (NCCAH), is the milder form of the 21-hydroxylase deficiency, with the estimated incidence of 1:1000 worldwide.<p...

Adrenocortical carcinoma (ACC) is a rare neoplasm with poor prognosis. Patients can present signs of hormone excess: virilisation, Cusging’s syndrome or only enlarged abdominal mass. Incidentally ACC can be also detected in the ultrasonography. Some of ‘non-hypersecretory’ ACCs can produce non-bioactive hormones steroid precursors or not very big amount of them and sometimes patients present subclinical Cushing’s symptoms. Surgery and adjuvant radiotherapy ...

BackgroundIn about 2/3 of pheochromocytoma patients, no pathogenic germline variant can be identified that might be responsible for the onset of the disease. However, in many patients, we observe the repeated appearance of one or more common polymorphisms in the gene RET. Each of them has been shown to be of no significance for pheochromocytoma and multiple endocrine neoplasm type 2 development, when analysed individually. We decided to test whe...

Introduction: There are data reporting an increased risk of cardiovascular and metabolic complications in patients with NCAH. This is frequently attributed to glucocorticoid (over)use. It seems that long-term exposure to increased androgens concentration may also itself lead to diminished insulin sensitivity and increased risk of prediabetes and diabetes.Aim: The aim of the study was to assess the link between NCAH diagnosis and glucose metabolism distur...

Introduction: Acromegaly is a disease associated with increased secretion of growth hormone and subsequent growth of bones, soft tissues and internal organs. An important factor influencing therapeutic treatment in recent years is the patient’s quality of life associated with the disease. In patients with acromegaly, it is significantly affected by the occurrence of depression and anxiety - agents undergoing treatment, which, however, still appear undiagnosed.<p class...

Classical form of congenital adrenal hyperplasia (CAH) is associated with the impairment of enzymes involved in process of adrenal steroidogenesis. More than 90% of CAH cases are connected with mutations in the 21-hydroxylase gene CYP21A2 in the HLA class III area on the short arm of chromosome 6p21.3. CAH is characterized by a strong correlation between the genotype and the phenotype. Mutations in the CYP21A2 gene can cause different degrees of loss of 21-hy...

Introduction: Adrenal incidentaloma is an adrenal mass found on imaging studies done for other reason than suspected adrenal disease. The majority of them are non-functioning adenomas, however pheochromocytomas could be also observed. Currently, in diagnosis of incidentalomas, the assessment of hormones of adrenal cortex and medulla is performed. The aim of the study was to assess the incidence of pheochromocytoma in patients with incidentaloma.Methods: ...

The prevalence of adrenal incidentalomas in computed tomography (CT) studies ranges from 0.6–1.9%. Adrenal masses are detected bilaterally in 10–15% of the cases.Non-classic adrenal hyperplasia (NCAH), also termed as late onset of CAH, is a very mild form of 21-hydroxylase deficiency. The incidence of disease is estimated at 0.1% of population. Reported prevalence in women with androgen excess range from 0.6 to 9%.Some pa...
