Background: Primary adrenal Non Hodgkin Lymphoma (NHL) accounts for less than 1% of all NHL cases. Among them, Diffuse Large B Cell Lymphomas (DLBCL) are the most commonly identified. Seventy percent of cases are bilateral and adrenal insufficiency usually occurs. Here we describe a case of a DLBCL with bilateral adrenal involvement and adrenal insufficiency.Clinical case: A 68 years male with a personal history of malaria, asthma, hypertension and chole...

Paragangliomas (PG) originating from the nasal cavity are very rare and usually have an indolent growth. Surgery offers the only possibility of cure for these patients while radiotherapy can only slow their growth rate. Intracranial or leptomeningeal dissemination is very rare, with only 7 cases described in the literature. A 77 year old man with a 4-years history of nasal obstruction. He underwent a nasofibroscopy with a biopsy that revealed a nasosinusal neuroendocrine tumou...

Introduction: The pseudohypoparathyroidism (PHP) encompasses a heterogeneous group of diseases characterized by end-organ resistance to parathyroid hormone (PTH). PHB type 1b (PHP1b) presents with PTH resistance at the renal proximal tubule, sometimes with TSH resistance, usually in the absence of Albright’s hereditary osteodystrophy (AHO) clinical features.Case report: A 64-year-old male was referred to endocrinology department for hypocalcemia. He...

Introduction: Arthropathy affects the majority of acromegalic patients and is a major cause of morbidity, absenteeism and impaired quality of life. GH excess and increased levels of circulating IGFI result initially in a marked thickening of the soft tissues and cartilage. Along with disease progression, there’s subperiostal bone neoapposition, cartilage regressive phenomena and bone structural changes. We aimed to investigate prevalence, clinical presentation, treatment ...

Introduction: Post-surgical hypoparathyroidism is a well known complication of total thyroidectomy. It may occur as transitory hypoparathyroidism that spontaneously recover within a few weeks/months and as permanent hypoparathyroidism needing long-term treatment. Only few cases of hypoparathyroidism newly diagnosed many years after surgery have been reported. We present a patient with hypoparathyroidism that became clinically evident 15 years after the thyroid surgery.<p c...

Introduction: Generously supported by IPSEN)-->Dopamine agonists (DA) effectively normalize prolactin secretion and reduce tumour size in most patients with macroprolactinomas. However, some patients are considered partially/totally resistant. Some authors propose that patients treated for 2 years, with normal prolactin secretion with low dose AD and maximal tumour diameter reduction >50%, could suspend treatment, but relapse rat...

Generously supported by IPSEN)-->Insulin and somatotropin (GH) have opposite effects in glucose metabolism. GH increases the production of glucose through lypolisis and inhibits hepatic and peripheric neoglucogenesis induced by insulin. When insulin secretion is insufficient to overcome insulin resistance, intolerance to glucose or diabetes appears. Drugs used in the treatment of acromegaly also influence glucose metabolism: SSA decr...

Glucocorticoids (GCs) are steroid hormones, products of the hypothalamic–pituitary–adrenal axis. Synthetic GCs, such as dexamethasone, have been widely used in the treatment of inflammatory diseases like rheumatoid arthritis or asthma, but their long-term use causes severe side effects (osteoporosis, diabetes, hypertension, etc). The ligand-bound GC receptor (GR) can activate gene expression via binding to GC response elements (GREs), a mechanism known as transactiva...

IntroductionPrader-Willi syndrome (PWS) is a multisystemic genetic disorder caused by lack of expression of genes on the paternally inherited chromosome 15q11.2-q13 region. Despite PWS present manifestations from birth, affected individuals can remain undiagnosed until adulthood.Clinical caseWoman, 40 years old, with cognitive impairment, referred to endocrinology due to morbid obesity (BMI 44.5 Kg/m2</s...

Backgroud: Distant metastases from papillary thyroid cancer (PTC) are infrequent and associated with poor prognosis. Adrenal metastatic lesions in this setting are rare, generally associated with lung and skeletal metastases. There have been few reported cases of isolated adrenal metastases from thyroid carcinoma. Here we report a patient with a PTC who developed a large and solitary adrenal metastasis.Case Presentation: A 68-year-old men was submitted i...
