Introduction: Struma ovarii is a rare form of ovarian teratoma mostly composed of thyroid tissue. In about 5% of the cases, well-differentiated thyroid carcinoma may arise in struma ovarii. As this medical entity is so exceptional, there is still no consensus on diagnosis and treatment.Case Reports: A 52-year-old old woman was submitted in 2009 to total hysterectomy with bilateral adnexectomy and pelvic lymphadenectomy. Histopathology r...

Introduction: The Bethesda System for Reporting Thyroid Cytopathology is the standard for interpreting fine-needle aspiration (FNA) and created a new diagnostic category (III): ‘atypia of undetermined significance/follicular lesion of undetermined significance’ (AUS/FLUS). The risk of malignancy for this category has been ascribed of 5–15% but the real malignancy rate remains unclear and plays a key role to define appropriate management.Ob...

Introduction: Primary hyperparathyroidism (PHPT) is a common endocrine disorder characterized by hypercalcemia due to an unregulated overproduction of parathyroid hormone (PTH). PHPT is most commonly caused by a single adenoma of the parathyroid gland, usually located just behind the thyroid gland. However, in rare cases, they can have an ectopic location, including intrathyroid adenomas. In some cases, the measurement of intact PTH in the wash out fluid obtained by US-Fine Ne...

IntroductionRadioiodine whole-body scintigraphy plays an important role in the follow-up of patients with differentiated thyroid carcinoma (DTC), as it is highly accurate in detecting thyroid residues and recurrent disease. Unusual 131-iodine uptake outside the thyroid bed and areas of physiological uptake is strongly suggestive of distant metastasis. However, uncommon uptake may occur and lead to diagnostic errors.Case report<...

We report an interference in an immunoassay for aldosterone, which potentially could have led to a wrongful diagnosis and unnecessary surgery. The interference was serendipitously recognized due to a preanalytical error. A 59-year-old female patient with hypertension was referred to the department of endocrinology after an adrenal incidentaloma was detected. Because of her hypertensive history, screening for primary hyperaldosteronism was performed. An elevated aldosterone and...

Introduction: The bone-sparing effect of oestrogen is mediated via oestrogen receptor alpha (ERα), which stimulates transcriptional action through its two activation functions (AF1 and AF2). In addition to these nuclear effects, a fraction of this receptor is targeted to the plasma membrane and triggers membrane initiated steroid signaling (MISS). Whereas, ERα AF1 plays a crucial role in trabecular bone, but not cortical bone, ERα AF2 is necessary for the oestro...

Introduction: Cushing’s disease (CD) is a severe disease, associated with an increased rate of comorbidities and mortality. Remission rate after surgery of pituitary tumor, is around 78%. Relapse occurs in 13% of patients within 10-years after surgery. According to guidelines, patients with unfeasible or non-curative surgery, require additional treatment, including medical therapies. Metyrapone, inhibits 11ß-hydroxylase enzyme, blocking the final step of cortisol syn...

Primary hyperparathyroidism is the third most common endocrine disorder, caused, in the majority of cases, by a single parathyroid adenoma and rarely by multigland adenoma or parathyroid carcinoma. Giant parathyroid adenomas, defined as larger than 3 g, represent an uncommon cause of primary hyperparathyroidism, with only a few cases described in the literature. We present the case of a 47 years old female who presented with a significant, unpainful, left cervical mass associa...

Background: Aldosterone-producing adenomas (APA) are a major cause of primary aldosteronism. Somatic mutations explain the excess aldosterone production in the majority of patients with APA with mutations in the potassium channel KCNJ5 the most prevalent. In contrast, mechanisms driving cell proliferation are largely unresolved.Objective: To identify genes that modulate cell growth in APAs.Methods: Quantitative transcripto...

Introduction: Turner syndrome (TS) is characterized by the complete or partial loss of one X chromosome and associated with a wide range of clinical manifestations. The clinical appearance depends on the specific karyotype, which may include different mosaic forms. Main features of almost all the karyotypes are short stature and delayed or absent puberty. Adult women in particular are at high risk of developing cardiac complications, metabolic syndrome, increased liver enzyme ...
