Introduction: Parathyroid carcinoma is a rare endocrine malignancy accounting for <1% of all cases of hyperparathyroidism. Diagnosis and treatment is still difficult.Case report: A 32-year-old women was admitted to the hospital because of mental status changes, polyuria, polydipsia, musculoskeletal pain and weight loss (34 kg during last year). She had history of nephrolithiasis, pancreatitis, cholelithiasis, peptic ulcer disease, osteoporosis and di...

Introduction: Ectopic release of ACTH caused by pheochromocytoma is extremely rare. The clinical picture of hypercortisolism is overlapped by catecholamine excess that makes diagnosis more difficult.Case report: A 74-year-old women was admitted to the hospital because of hypertension, recently diagnosed diabetes and weight loss (10 kg per six months). In physical examination: cachexia, dehydratation, pallor, hirsutism, proximal muscle weakness, elevated ...

Introduction: Cushing’s disease (CD) is the most common cause of hypercortisolism. Therefore, the majority of studies focused on the efficacy and safety of novel steroidogenesis inhibitors included CD patients only. This is exactly the case with osilodrostat – new potent inhibitor of 11β-hydroxylase. However, approximately 10% of hypercortisolism result from cortisol-secreting adrenal adenoma. Data on potential differences in the treatment with osilodrostat betw...

Introduction: The mixed tumor which secretes an excess of both GH and TSH causing acromegaly and hyperthyroidism is rare. The main problem is the late diagnosis, especially in men, even 10 years after the occurrence of the first symptoms.Case report: A 53-year-old men, was admitted to the our department, with complaints of excessive sweating and enlargement of the hands. His medical history included arterial hypertension. Past medical history revealed th...

Introduction: Polycystic ovary syndrome (PCOS) is characterized by menstrual disorders, hyperandrogenism and polycystic ovaries on ultrasonography. This hormonal disorder is also strongly associated with insulin resistance. The diagnosis of PCOS can be established after the exclusion of other causes of mentioned symptoms, such as non-classic congenital adrenal hyperplasia (NCAH). To date, several studies suggest the increased serum concentration of 17-hydroxyprogesterone (17-O...

Understanding the genetic etiology of Graves’ disease (GD) and Graves’ orbitopathy (GO) is recognized as an urgent priority. Since peroxisome proliferator-activated receptors α (PPARα) exhibit anti-inflammatory and immunomodulatory activity, and are required for the control of the adipose inflammation process their role in the GD and GO pathogenesis has been proposed. Abnormal expression and/or function of PPARα could suppress the inflammatory response...

Introduction: Peroxisome proliferatior-activated receptor-γ2 (PPAR-γ2) plays a crucial role in adipogenesis and has been shown to be involved in the control of immunoregulation and inflammation. Orbital fibroblast differentiation to adipocytes is a PPAR-γ dependent process essential for pathogenic tissue remodeling in Graves’ orbitopathy (GO). Genetic variation in PPAR-γ2 gene may modulate expression and/or function of molecule encoded by this gene.</p...

Introduction: Both genetic and environmental factors contribute to clinical manifestation of Graves’ disease including the response to medical therapy. CTLA-4 gene is an important inhibitor of T-cell activation and its polymorphisms may influence the course of the disease.Goal: We investigated the association between CTLA−4 gene polymorphisms: c.49A>G, g.319C>T, g.*642AT(8_33), CT60, and Jo31 and the response to ph...

Iatrogenic Cushing syndrome caused by the use of steroid medications is common because of the widespread use of these medications for the treatment of many diseases, however development of Cushing syndrome from the topical corticosteroids is very rare in adults.A 45-year-old men (BMI: 44 kg/m2), with a history of psoriasis, developed manifestations of Cushing syndrome, which included weight gain, central obesity, moon face, facial plethora, bu...

Objective: It has been shown that women with PCOS as well as with autoimmune thyroiditis (AIT), are characterized by increased incidence of infertility. Serum anti-Müllerian hormone (AMH), which reflects ovarian reserve, is elevated in PCOS women and is decreased in women with AIT. The Rotterdam criteria recognize four clinical PCOS phenotypes,i.e.,phenotype Acharacterized by clinical and/or biochemical hyperandrogenism (HA), menstrual dysfunction (oligo/amenorrhea) (Olig...
