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...

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...

IntroductionSilent corticotroph adenoma represent an uncommon subtype of nonfunctioning adenoma, immunoreactive for ACTH, without clinical or biochemical evidence of hypercortisolism and unclear pathogenesis. Usually, they present with local mass effect (visual deterioration being the most common) and endocrine dysfunctions. They carry a more aggressive behavior, particularly upon earlier recurrence.Case presentation<p class="a...

Introduction: Ectopic ACTH syndromes account for 5–10% of Cushing syndrome, with intrathoracic and gastrointestinal–pancreatic neuroendocrine tumors being the most common causes, followed by small cell lung cancer, adrenal paraganglioma and medullary thyroid carcinoma.Case report: A 50-year-old male hypertensive and diabetic patient was transferred to our clinic for emergency endocrine care for hypokalemia. He had mild hypercortisolism and live...
