Introduction: Amyloidosis is a disease characterized by the accumulation of an amorphous proteinaceous material, known as amyloid, in various organs and tissues of the body. Amyloid goiter is a remarkably rare pathologic condition due to thyroid massive amyloid infiltration of amyloid light chain (primary) or amyloid A (secondary amyloidosis) proteins. Case: 54 year-old male, with known history of chronic tophaceous gout medicated with anakinra and predn...

Introduction: Anomalies of glucose metabolism and insulin resistance are common in patients with hypothyroidism. Some studies suggests that euthyroid autoimmune thyroiditis (AIT) may also be associated with changes of glucose metabolism and insulin resistance. The role of thyroid hormones resistance in this context is still uncertain.Aim: To evaluate the relationship between thyroid hormones resistance, insulin resistance and lipid profile in euthyroid p...

Primary bilateral macronodular adrenal hyperplasia (PBMAH) is a rare cause of Cushing’s syndrome (CS). It is a highly heterogeneous disease with multiple adrenal macronodules and variable levels of cortisol excess. The pathogenesis is complex and different mechanisms such as aberrant hormone receptors, local production of ACTH in adrenal tissues and genetic mutations have been identified. The approach is not well established. Nine patients with PBMAH who are currently fol...

Introduction: Black adrenal adenomas are rare and benign. They are named after their black appearance, due to lipofuscin pigment. Most frequently black adenomas are associated with ACTH-independent Cushing’s syndrome. They can also cause primary hyperaldosteronism or be nonfunctioning. Unlike most other adrenal adenomas, black adenomas exhibit high Hounsfield units (>30) on CT, and high standard uptake value on FDG-PET.Case presentation: A 67-ye...

Introduction: The small-cell neuroendocrine prostate carcinoma (SCPC) is rare, highly aggressive and usually transforms from prostate adenocarcinoma (PAC) after androgen deprivation therapy (ADT).Case Report: A 66-year-old man had a three-year history of high-grade PAC with high burden disease (abdominal lymph node and bone metastasis) at presentation (09/2019). On the initial staging evaluation, the CT scan documented a 20 mm left adrenal nodule compati...

Introduction: The 22q11.2 deletion syndrome or DiGeorge syndrome (DGS) is rare and the diagnosis in adults is uncommon. The phenotype is highly heterogeneous and of variable severity, including hypoparathyroidism and epilepsy.Case Report: A 26-year-old man was admitted in the emergency room for inaugural tonic-clonic seizure. He had history of cognitive impairment and learning difficulties. Neurologic examination, brain CT and basic analysis were irrelev...

Introduction: In patients with ACTH-dependent Cushing Syndrome, differentiating between pituitary and ectopic sources can be challenging. Noninvasive testing can be performed, but bilateral inferior petrosal sinus sampling (BIPSS) remains the gold standard. In the last years however, novel imaging modalities, namely 3T-MRI with 3-dimensional spoiled gradient-echo sequence and 68Ga-tagged CRH combined with positron emission tomography, have been proposed as alternatives.<p ...

Introduction: Follicular thyroid cancer (FTC) accounts for 12% of differentiated thyroid cancers (DTC). It is frequently complicated by bone metastasis (BM), which impact quality of life (QOL) and decreases the 10-year survival rate to 13-21%.Case Report: A 53-year-old woman followed at the Pain Clinic for over 10 years for lower back pain, had been operated three years before due to lumbar disc herniation. Pain relapsed one year after surgery and was re...

Introduction: Central obesity and the consequent metabolic syndrome have global devastating effect on the health system due to their strong association with type 2 diabetes mellitus and cardiovascular disorder. There are contradictory results about the influence of insulin resistance and visceral adipose tissue on bone phenotype. The study was designed to evaluate the association between bone quality and bone mineral density (BMD) with bone marrow adipose tissue (MAT) as well ...

Introduction: People living with human immunodeficiency virus (HIV) are at increased risk of developing metabolic disorders, such as obesity, dyslipidemia, insulin resistance, diabetes and hypertension; which may also be associated with hypercortisolism. Due to the similarity between the metabolic changes present in these two clinical situations, several studies have evaluated whether HIV-infected patients have increased levels of cortisol, but the results are not consensual. ...
