Pheochromocytoma is a rare tumor made up of chromaffin cells from the adrenal medulla that secrete catecholamines. It can occur at any age, with a peak incidence between the fourth and fifth decade of life, and only 10% of cases occur in children. The majority of cases are sporadic and approximately 10% are malignant. The existence of familial syndrome, multiple or extra adrenal tumors is more common at younger ages. The clinic is very variable, and hypertension (HTA) is the m...

Introduction: MODYs are being identified more frequently but the rarity of some types still precludes in-dept knowledge of their natural course of disease. One of this rare forms is MODY 5, the result of a mutation on the hepatocyte nuclear factor 1 beta (HNF-1B) gene that associates with genitourinary and pancreatic malformations/dysfunction.Case report: A 24-year-old female was referred to the Endocrinology clinic due to hyperglycaemia identified on pr...

A female patient was first referred to the Endocrinology department due to primary amenorrhea at age 37. She mentioned trans-sphenoidal surgery at age 15 due to a craniopharyngioma and the indication to be supplemented with hydrocortisone (HC) and DDAVP, that she adhered to until age 20, when she abandoned all appointments. Apart from that, she mentioned normal pubertal development and said she was generally healthy. She denied any episodes compatible with Addisonian crises. F...

Introduction: Primary lymphoma of the thyroid (PTL) is a rare cause of malignancy, accounting for 5% of thyroid malignancies, with an annual estimated incidence of 2 per 1 million. Women are more commonly affected than men (2–8:1). Patients typically present in the sixth or seventh decade of life. Most thyroid lymphomas are non-Hodgkin’s lymphomas (NHLs) of B-cell origin. Patients with Hashimoto’s thyroiditis are at greater risk for developing PTL. Treatment and...

Introduction: Increasing incidence of thyroid cancer might be a consequence of an increase detection of subclinical disease. The aim of this study was to compare the clinical and pathologic characteristics of nonincidentally discovered (NID) thyroid cancer with incidentally discovered (ID) on postoperative pathology.Methods: A retrospective medical record review of 104 patients with thyroid cancer was performed. A group I of 69 patients with NID thyroid ...

Introduction: Mauriac syndrome is characterized by delayed growth and development, obesity, hepatomegaly and elevated transaminases in type 1 diabetes mellitus (T1DM) patients who have poor glycaemic control. Usually recognized in adolescence, when growth failure and pubertal delay became notorious.Case report: A 19-year-old male was referred to the Endocrinology Department due to short stature. He was severely distressed about his stature and younger ap...

Introduction: TSH-secreting adenomas represent <2% of pituitary tumors. Surgery and/or radiotherapy are primary treatment options. Somatostatin analogues and also dopamine agonists, represent valuable alternatives or adjuvant therapies.Objective: To report a case of euthyroidism and tumor stability achieved in a TSH-secreting pituitary macroadenoma, treated with octreotide-LAR, as first line therapy, and then added cabergoline. To review the efficacy...

Background: Agranulocytosis is rare and may develop in 0.2–0.5% patients using antithyroid drug therapy (ATD). We report on a patient who developed febrile neutropenia two weeks after starting treatment with methimazole.Case Report: A 74-year-old female, with no relevant medical history, was diagnosed with Graves disease and treated with methimazole (30 mg/day). Three weeks after starting therapy she presented to the emergency department with compla...

Background: Pheochromocytoma is a rare catecholamine secreting tumor originating usually from adrenal medulla and representing approximately 5% of adrenal incidentalomas. Currently 10% of all pheochromocytomas are discovered incidentally during imaging studies for unrelated disorders.Case presentation: A thirty five year old woman with no relevant medical history presented at the emergency department with symptoms of left flank pain and vomiting. Abdomin...

Introduction: Adrenal incidentalomas (AIs) are defined as adrenal masses measuring 10 mm or more in diameter, incidentally discovered on imaging exams performed for a non-adrenal disorder. The aim of this study is to provide a clinical and imagiological characterization of patients diagnosed with AIs followed in our institution.Methods: We conducted an observational and retrospective study that included patients with AIs evaluated at our institution betw...
