Cancer immunotherapy has introduced a novel class of drugs known as immune checkpoint inhibitors (ICIs). They enhance antitumour immunity by blocking negative regulators (checkpoints) of T cell function that exist on both immune and tumour cells. ICIs targeting CTLA-4 and PD-1/PDL-1 have dramatically changed the outcome of patients with several advanced-stage malignancies but they may lead to a variety of inflammatory toxicities and autoimmune consequences. The main endocrine immune-related adverse events (IRAEs) include hypophysitis, primary thyroid dysfunction, adrenalitis and type 1 diabetes mellitus...

RATIONALE: The incidence of severe hyperandrogenism associated with masculinity in women is very low. While rare and difficult to diagnose, androgen secreting tumors should be suspected in women with hyperandrogenism and hirsutism, especially in the postmenopausal population. Herein we present one case of ovarian Leydig cell tumor (LCT) with markedly elevated serum testosterone levels and frank hirsutism. PATIENT CONCERNS: A 60-year-old woman, presented with increased hair growth and androgenic alopecia and the hormonal laboratory examination showed that she had elevated serum testosterone level and normal dehydroepiandrosterone sulfate (DHEAS), androstenedione, 17- hydroxyprogesterone, cortisol and thyroid stimulating hormone (TSH)...

Myxedema may be the first presentation of patients with undiagnosed hypothyroidism. Definitive management is with thyroid hormone but supportive measures, identification and treatment of precipitating factors in an appropriately safe environment are vital. There is no consensus about preferred thyroid hormone regimen. Corticosteroid therapy is given until adrenal insufficiency has been excluded. We present here a case of seventy-four years old woman of myxodema coma.

INTRODUCTION    RANTES (Regulated on Activation, Normal T-cell Expressed and Secreted) chemokine, the product of CCL5 gene, is involved in trafficking immune cells into the inflammation site. It acts as co-activator of T cells and promotes polarization of the immune response towards the Th1 profile. In autoimmune Addison's disease (AAD) adrenal cortex is gradually destroyed by adrenal-specific immune cell infiltration. RANTES might be implicated in autoimmune adrenal failure through recruitment and activation of the immune cells...

Thyroid follicular cells, as well as adrenocortical cells, are endowed by an intrinsic heterogeneity regarding their growth potential, in response to various stimuli. This heterogeneity appears to constitute the underlying cause for the focal cell hyperplasia and eventually the formation of thyroid and adrenal nodules, under the influence of growth stimulatory factors. Among the main stimulatory factors are the pituitary tropic hormones, thyroid-stimulating hormone (TSH) or thyrotropin and adrenocorticotropic hormone (ACTH), which regulate the growth and function of their respective target cells, and the insulin/insulin-like growth factor system, that, through its mitogenic effects, can stimulate the proliferation of these cells...

Autoimmune Addison's disease (AAD) is the most frequent cause of adrenocortical insufficiency. The natural history of AAD usually comprises five consecutive stages with the first stage characterized by the increase of plasma renin consistent with the impairment of pars glomerulosa, which is usually the first affected layer of the adrenal cortex. We describe a 19-year-old female with Hashimoto's thyroiditis (HT) who underwent an autoantibody screening due to having the personal and family history of other autoimmune diseases in the absence of relevant clinical manifestations...

We describe a very rare case of concurrent variant type 3 autoimmune polyglandular syndrome (APS) and pulmonary arterial hypertension (PAH). A previously healthy 65-year-old Japanese woman was referred to our university hospital with a 2-month history of general fatigue and hyperglycemia. Laboratory tests revealed severe hyperglycemia (plasma glucose 543 mg/dL and HbA1c 10.7%) with ketonuria (3+). Glutamic acid decarboxylase (GAD) and IA-2 antibodies were positive, and the serum C peptide level was markedly decreased to 0...

INTRODUCTION: In the MEN 2A syndrome, which is the most common of the three types of MEN, three endocrine systems are affected simultaneously or subsequently by the development of tumours manifested by medullary thyroid gland carcinoma, pheochromocytoma (often bilateral) and hyperparathyroidism. MATERIAL AND METHODS: 27 patients from 3 families affected by MEN 2A syndrome were examined clinically (by detecting the effects of catecholamine overproduction), biochemically (screening for metanephrine and normetanephrine in the serum), visualization (CT, MRI, MIBG, PET CT) and some of them also genetically (DNA fragment analysis obtained by PCR amplification)...

Multiple endocrine neoplasia type 2A (MEN2A) is a hereditary syndrome. Here, two different RET proto-oncogen mutation were identified from family members of two MEN2A pedigrees by genetic screening. One RET mutations were found at codons 1893 and 1895 in exon 11 (1893-1895delCGA) from pedigree 1, which is a novel mutation, the other occurs at codon 634 (Cys634Arg) in exon 11 from pedigree 2. However, the clinical characteristics were similar in the patients of the two pedigrees. All the patients were in middle-age at onset...

Endocrine paraneoplastic syndromes result from the production of bioactive substances from neoplastic cells, of endocrine or neuroendocrine origin. Typically these are located in the lungs, the gastrointestinal tract, pancreas, thyroid gland, adrenal medulla, skin, prostate or breast. In endocrine paraneoplastic syndromes the secretion of peptides, amines or other bioactive substances is always ectopic and not related to the anatomical source. The clinical presentation, however, is indistinguishable from a suspected eutopic endocrine tumor posing a diagnostic challenge...

OBJECTIVE: Klinefelter Syndrome (KS) is the most common sex chromosome aneuploidy in males. As well as classic KS, less frequent higher-grade aneuploidies (HGAs) are also possible. While KS and HGAs both involve testicular dysgenesis with hypergonadotropic hypogonadism, they differ in many clinical features. The aim of this study was to investigate the endocrinal and metabolic differences between KS and HGAs. DESIGN: Cross-sectional, case-control study. METHODS: 88 patients with KS, 24 with an HGA and 60 healthy controls...

A 61-year-old woman with newly diagnosed anaplastic thyroid cancer and known metastases to the brain, lungs, and adrenal glands complained of groin muscle pain. F-FDG PET/CT was performed to assess for extent of disease and showed extensive hypermetabolic lesions throughout the skeletal musculature concerning for metastatic disease. As this would be a very rare presentation for anaplastic thyroid carcinoma, a biopsy of the left gluteal muscle was conducted. Pathology demonstrated anaplastic thyroid carcinoma, metastatic to skeletal muscle...
