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: 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: Pseudohypoparathyroidism (PHP) is a rare disorder characterized by parathormone (PTH) resistance, caused primarily by genetic defects involving the alpha-subunit of the stimulatory G protein. Biochemical and molecular analysis classify pseudohypoparathyroidism into types I-a, I-b, I-c and 2. We report a case of PHP I-b in an adolescent presenting with a neurological disorder.Case Report: 11 years old female patient, with no relevant persona...

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...

Objective: Describe clinical, laboratorial, imaging features, therapeutic management and the outcomes of patients with clinically non-functioning pituitary adenomas (NFPAs) presenting at our department.Methods: Retrospective review of electronic medical records of all patients with NFPAs evaluated at our department between 2010 and 2019.Results: We evaluated 160 patients, 51.3% female, with a median age of 56.6 years (18–89). ...

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: Silent somatotroph tumors (sST) are a pituitary neuroendocrine tumor subtype with positive immunostaining for growth hormone (GH) but without the presence of acromegaly. Unlike silent corticotroph tumors, there is little information in the literature on sST. The aim of the present study was to study the demographic, clinical and molecular characteristics in a series of ST in order to compare sST and functioning ST (fST).Methods: We have stu...

Background and Aims: Diabetes is often associated with an increased severity and mortality in COVID-19 patients. Possible mechanisms include hyperglycemia-induced impaired immune response, characterized by a state of chronic low-grade inflammation. Objectives: evaluate if diabetes and glycemic control were related to the severity of disease and mortality in hospitalized COVID-19 patients.Methods: We conducted a retrospective case control study that inclu...

Introduction: Recently we have demonstrated the contribution of the quantification of expression of adenohypophyseal hormone genes in the identification of the different Pituitary Neuroendocrine Tumor (PitNET) subtypes according to the 2004 WHO criteria.Aim: The aim of the present study was to evaluate the contribution of the quantification of expression of pituitary transcription factor genes to the identification of PitNETs according to 2017 WHO criter...
