Introduction: Prostate cancer is the second most frequent malignancy in men, with more than 1.4 million new cases diagnosed in 20201. Obesity, on the other hand, has reached epidemic proportions, with 59% of adults living with overweight or obesity in Europe2. Our aim was asses the impact of weight and BMI on prostate cancer (PCa) severity, reflected in PSA levels.Methods: We analyzed 225 patients diagnosed with PCa between August 2...

Background: Melatonin and cortisol production demonstrate circadian rhythms; disruption of these rhythms feature in endocrine and neurodegenerative disorders, such as Addison’s disease, Huntington’s disease (HD) and Alzheimer’s disease (AD). Measuring serum and saliva concentrations at nadir is challenging using immunoassays. We have developed LC-MSMS methods for measuring serum and saliva melatonin, cortisol and cortisone to analyse 24hr profile samples obtained from sleep st...

Introduction: Clear cell renal carcinoma (ccRCC) is a subtype of renal cell carcinoma, the most frequent one (80%) and usually affecting only one kidney. It is twice as common in men than women between 50 to 70 years old. It can be associated with some genetic conditions that predispose patients to ccRCC, like Von Hipple-Lindau disease. Some clinical observations and molecular studies raised the hypothesis that RCC is a hormone−dependent tumor.Case...

Background: Papillary thyroid cancer (PTC) incidence has increased substantially over the last decades. Although 4% of thyroid cancers may induce a sarcoid reaction in the thyroid gland, sarcoidosis (SA) as a disease may exist with PTC, although causality remais uncertain and their coexistence is rarely reported in the literature. They occurs in both genres, between 30–40 years, but females are more predisposed.Case presentation: A 65-year-old man, ...

Introduction: Central diabetes insipidus is a rare disorder, characterized by a failure of the posterior pituitary to produce vasopressin that lead to hypotonic polyuria and polydipsia. Diabetes insipidus may be due to post-pituitary surgery, where sometimes the posterior lobe also has to be removed or damaged; other injury as fractures of the skull, trauma, infiltrative lesions, tumors/metastases, idiopathic or rare genetic causes. As the sensation of thirst is the key homeos...

Multiple endocrine neoplasya type 2 (MEN-2) is a rare hereditary complex disorder caused by a germline activating mutation of the RET proto-oncogene. The estimated prevalence is approximately 1:30.000. Three clinical forms have been described depending on the phenotype: MEN2A (80%), MEN2B and familial medullary thyroid carcinoma (MTC).Clinically, MEN2A present with MTC (80–100%), unilateral or bilateral pheocromocytoma (40%) and primary hyperparath...

Neuroendocrine tumors are rare in young patients and usually have favorable course. We present a case of young, 13-year-old girl diagnosed with insulinoma. The diagnosis was stated on the basis of the presence of neuroglycopenic symptoms. An abdominal CT scan demonstrated a tumor localized in the head of pancreas. The patient received diazoxide as a preparation to surgery. Therapy was effective, but discontinued due to side effects. Patient underwent the Whipple operation. Dur...

Introduction: Incidence of ectopic parathyroid glands in individuals is ~6%, the most common location being the thymic capsule or the superior mediastinum.Case: We present the case of 21-years-old female with a recent history of osteoclastoma affecting the maxillary bone and the mandible, together with increased values of the parathyroid hormone (over 20 times the normal value), total calcium and alkaline phosphatase and decreased serum phosphorus. A cer...

Introduction: The ectopic thymus tissue (ETT) represents a migration and descending deficiency of the organ during embryogenesis.HMWK have a strong positive reaction in normal anatomical localized thymus and thymomas. A similar reaction pattern is seen in thyroid solid cell nests (SCNs) suggesting that these cells share a common origin with thymic tissue. Moreover, can be very helpful in differentiate CASTLE from other thyroid tumors.<p class="abstex...

Introduction: Thyroid follicular adenomas (FA) and adenomatous nodules (AN) – lesions frequently found in areas with iodine deficiency, can be normo-/hypofunctioning (scintigraphically cold – SCN) or hyperfunctioning (scintigraphically hot – SHN) nodules.Aim: Evaluation of proliferation potential in thyroid nodules on tissue samples obtained at surgery from euthyroid patients clinically diagnosed with SCN and from patients with thyroid hyp...
