Introduction: The adrenocortical carcinoma (ACC) is a primary malignant tumor developed in depends of the adrenal cortex, defined by a Weiss score ≥3. Despite the therapeutic progress, its prognosis is still severe.Patients and methods: This retrospective descriptive study evaluated 4 patients with adrenal corticosteroid followed in the endocrinology department of Sfax - Tunisia between 2010 and 2018.Results: There were 3 wom...

Introduction: Thyrotropin-secreting pituitary adenomas represent less than 1% of all pituitary adenomas. Usually, patients present mild or moderate signs of hyperthyroidism and Hormonal evaluation shows increased free thyroid hormone concentration with detectable, normal or increased serum thyrotropin (TSH) level. Herein we report three cases of thyrotropin adenomas with particular clinical and biological features.Observations: Three patients, aged 25 38...

Introduction: Ganglioneuroma is a rare benign tumour arising from neural crest sympathogonia. It is usually asymptomatic and non functional. An association between ganglioeneuroma and genetic or autoimmune diseases such as Addison’s disease or Mediterranean fever has never been described.Case description: We report the case of a 24-year-old woman presenting with paroxysmal abdominal pain with loss of weight and no fever. Physical examination along w...

Introduction: The otorhinolaryngologist can be confronted to multiple surprises after a thyroid surgeryCase description: We report the case of a 48 year-old woman admitted with post operative hypocalcaemia (after thyroidectomy?). The patient has a history of hypothyroidism since 5 years. She then presented a cervical swelling. The ultra-sound confirmed the presence of a suspicious thyroid nodule measuring 4 cm. A thyroidectomy was then conducted. Post op...

Background Ghrelin stimulates cell proliferation in a number of tissues including pituitary. AMPK, a heterotrimer kinase enzyme, is an important sensor and regulator of cellular energy balance. We have shown that ghrelin can change AMPK activity in various tissues and this mechanism could play a role in its metabolic effects. AMPK has recently been established to strongly inhibit cell proliferation and tumorigenesis. We therefore hypothesised that ghrelin stimulates cell proli...

Introduction: Dysthyroidism is not uncommon during chromosomal aberrations. The objective of this work is to study the characteristics of this association at the epidemiological and clinical levels.Methods: This is a retrospective study of 27 cases of patients with trisomy 21 chromosomal abnormalities (6 cases), klinefelter syndrome (4 cases) and Turner syndrome (17 cases) genetically confirmed, collected at endocrinology service at Sfax University Hospi...

We present the case of an octogenarian with a major history of lambda light chain myeloma which was treated by a first-line lenalidomide and dexamethasone from June 2018 to September 2019. Patient had also hypertension and valvular heart disease (mechanical valve and anticoagulation by acenocoumarol). In September 2019, a right adrenal mass was incidentally discovered by a renal ultrasonography made for acute kidney injury. The abdominal CT-scan confirmed the presence of a lar...

Introduction: Primary aldosteronism (PA) is associated with increased prevalence of metabolic disorders such as impaired glucose and lipid metabolism and insulin resistance. Individuals with PA have an increased risk of cardiovascular events. The aim of this study is to determine the characteristics of metabolic syndrome (MS) in patients with PA.Patients and methods: Retrospective study concerning 40 patients with PA over the period of 10 years from Janu...

Introduction: Allgrove syndrome or Triple A (3A) syndrome is a rare autosomal recessive disease characterized by alacrima, esophageal achalasia and adrenocorticotropic hormone-resistant adrenal insufficiency.Observation: A 3-year-old and 9 months patient, from a consanguineous marriage, consulted for melanoderma, with family history: sisters with an heterozygous mutation of the AAAS gene, two paternal cousins, 5 years and 22 years, followed for autism an...
