Introduction: Parathyroid hyperplasia is the second cause of primary hyperparathyroidism (PH), representing 15–20% of all cases. The scintigraphy with Tc-99m-Sestamibi is a preoperative exam used to identify parathyroid adenomas or hyperplasia. It has a sensibility of 50–90%, which increases with larger parathyroid size. The neck ultrasonography (US) has also an important role detecting parathyroid enlarged glands with 70% sensibility. We report a case of parathyroid...

Introduction: Hirsutism is the presence of terminal hair growth in females with a male distribution pattern. It affects 5-15% of women, being an important sign of androgen excess. The main causes of hirsutism are polycystic ovary syndrome (PCOS) and idiopathic hyperandrogenism. Other significant but less frequent causes of hirsutism include nonclassic congenital adrenal hyperplasia (NCAH), androgen-secreting tumors, and Cushing’s syndrome.Case repor...

Introduction: Primary Bilateral Macronodular Adrenal Hyperplasia (PBMAH) represents <2% of causes of Cushing’s Syndrome (CS). Clinical course is insidious, with adrenal bilateral macronodules and gradual cortisol excess, only rarely presenting with overt CS. The pathophysiology remains unclear, however, hyperactivation of the cAMP/PKA pathway, in 77-87% of cases through aberrantly expressed G-protein coupled receptors (GPCRs), has been described. Despite being a benig...

Introduction: Primary hyperparathyroidism (PHPT) is characterized by parathyroid hormone (PTH) overproduction, causing hypercalcemia. The most common cause is a parathyroid adenoma. PHPT most frequently presents as asymptomatic hypercalcemia or with nonspecific symptoms. Less frequently, it presents with the classical manifestations of bone disease and nephrolithiasis. Acute pancreatitis (AP) as the initial manifestation of PHPT has been reported rarely. Hypercalcemia can caus...
