Introduction: Pseudohypoparathyroidism is a heterogeneous disease characterized by hypocalcemia, hyperphosphatemia and parathyroid hormone resistance. The distinct pseudohypoparathyroidism types are distinguished by physical features, the coexistence of other hormone resistances and genetic defects. Pseudohypoparathyroidism type Ib is more often associated with sporadic cases, unlike others types.Clinical Case: Male, born in France, diagnosed with pseudo...

Introduction: Testosterone-based gender-affirming hormone therapy (GAHT) may have negative consequences on cardiovascular risk, with reported increased blood pressure, decreased HDL-cholesterol, and weight gain. Still, data on cardiometabolic changes in transgender men on GAHT remain controversial. Testosterone-based GAHT also modifies body composition and lean muscle mass, but the degree to which affects serum creatinine and other measures of kidney function is still not clea...

Introduction: Parathyroid carcinoma (PC) is an extremely rare malignancy. A complete surgical excision is often difficult, and persistent/recurrent disease occurs in up to 65% of cases. Progression often leads to symptomatic hypercalcemia, the major contributor to poor quality of life and mortality. Treatment options beyond surgical resection are limited. Denosumab is an approved therapy for refractory hypercalcemia of malignancy, and its use in unresectable PC has been descri...

False elevation of estradiol(E2) due to immunoassay interference is a rare but important phenomenon reported in the literature. It is most commonly related to cross-reactivity(CR) from drugs sharing structural similarity with E2, namely fulvestrant and exemestane. These laboratory interferences(LI) can lead to unnecessary investigation/inappropriate treatments. Therefore, in such instances, a more selective and sensitive method is required. We present the case of a young femal...

Introduction: The somatotropin deficit is one of the late consequences of cancer treatments. The administration of somatotropin implies treatment with daily injections, which hinders therapeutic adherence. This goal is a challenge for survivors and health professionals. Therapeutic education and new technologies are instruments that favor the training and development of control mechanisms that promote and motivate the behavior’s change.Objective: To...

Introduction: Prolactinomas are mostly benign tumours usually managed with pharmacological treatment. Some, however, seem to be resistant to dopamine agonists (DA) for unclear reasons. The relationship between T2W signal intensity (T2WSI) and response to treatment with somatostatin analogs is well described in acromegaly patients. Some evidence suggests that prolactinoma’s T2W hypointensity might be related to higher baseline prolactin levels and more resistance to DA.</p...

Introduction: DIPNECH is a preinvasive condition in which there is an idiopathic generalised proliferation of pulmonary neuroendocrine cells that can form tumourlets. There are very few cases described of ACTH secretion by these cells causing Cushing’s syndrome, some of them cyclic.Case report: A 41 year-old woman was sent to our Endocrinology outpatient clinic for menstrual disturbance, acne and excessive sweating. She had a recent diagnosis of DIP...

Introduction: First described in 2009, IgG4-related thyroid disease includes several subcategories: Riedel’s thyroiditis, fibrous variant of Hashimoto thyroiditis (FVHT), IgG4-related Hashimoto thyroiditis (HT) and Graves’ disease with elevated IgG4. It is rare, with most cases described in Japan and characterized by increased IgG4 plasma cells at immunostaining.Case Report: A 59-year-old Caucasian women, without known Asian ancestry, was obser...

Estrogen-producing adrenal gland tumors (EPAGT) are extremely rare, accounting for only 1–2% of all adrenal tumors. They are most commonly observed in men or in children, and are unusual in women. They are almost always malignant even if they seem benign at presentation, and most of them have a poor prognosis. We present a case of a 71-year-old man with painful bilateral gynecomastia, without galactorrhea, over 4 months. Markedly elevated plasma estradiol levels were foun...

Introduction: Cushing’s syndrome (CS) is a rare disease resulting from prolonged exposure to supraphysiological levels of glucocorticoids. Cushing’s Disease is the most frequent cause of endogenous CS. This disease has a broad spectrum of clinical manifestations and is associated with an increased morbi-mortality. Diabetes Mellitus (DM) and hypokalemic alkalosis affects up to 50 and 10% of CS patients respectively. Disease onset and severity reflects the magnitude of...
