An 82-year-old woman with a history of breast carcinoma and hypertension underwent right laparoscopic adrenalectomy for a large mass (7×5 cm) of high density without contrast (>30 UH), non-secreting. Anatomapathological examination concluded to an adrenocortical adenoma without signs of malignancy: Weiss score of 2 and Ki67 <2%. Two years later, she developed polycythemia (Hb: 17.9 g/dl (N: 11.8–15.5); hematocrit: 53.5% (N: 35.3–46.1)) without involvemen...

Introduction: Neurofibromatosis type 1 (NF1) is one of the most frequent genetic dominant syndrom in men with a prevalence of 1 in 2600 to 3000 individuals worldwide. NIH NF1 diagnostic criteria are driven by the most frequent manifestations of the disease (café au lait macules (CAL), neurofibromas, freckling, optic glioma, Lisch nodules and osseus lesions). There are many clinical manifestations of NF1 (neurological, cardiovascular, gastrointestinal, endocrine and orthop...

Introduction: Pheochromocytoma and paraganglioma (PPGLs) are rare neuroendocrine tumors. Some of them are catecholamine-secreting tumors responsible for hypertension or adrenergic symptoms. Among 10% are malignant with a higher rate of malignancy in the inherited syndromes. Management of patients with hereditary pheochromocytoma and PPGLs is well defined and standard treatment is surgical resection.Case report: We report the case of a 53-year-old man who...

Introduction: Measurements of midnight salivary cortisol, 24-hour urinary free cortisol (UFC) and 1mg overnight Dexamethasone (DXM) suppression test (short DST) represent classical first line screening tests to diagnose Cushing syndrome. In women using combined Estrogen–Progestogen contraception, cortisol response during short DST is often decreased, leading to false positive (FP = morning plasma cortisol post-DST > 50 nmol/l).Purpose: The main ...

Introduction: Cushing’s syndrome (CS) is a medical condition resulting from a chronic excessive exposure to glucocorticoids. ACTH-dependent CS are mostly caused by pituitary adenoma (about 80-85% of the cases) and, in a lower proportion, by ectopic ACTH secretion (about 10-15% of the cases). The exact origin of an ectopic secretion of ACTH is not always easy to identify. The most common locations are bronchus, lung and pancreas but it can also be located ...

Introduction: Neurofibromatosis type 1 (NF1) is one of the most frequent genetic dominant syndrom in men with a prevalence of 1 in 2600 to 3000 individuals worldwide. NIH NF1 diagnostic criteria are driven by the most frequent manifestations of the disease (‘café au lait’ macules (CAL), neurofibromas, freckling, optic glioma, Lisch nodules and bone lesions). There are many clinical manifestations of NF1 (neurological, cardiovascular, gastrointestinal, endocrine ...

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...

Introduction: Primary adrenal lymphoma is rare, representing less than 1% of non-Hodgkin lymphomas.1 The clinical presentation is non-specific, symptoms of adrenal insufficiency may occur with bilateral lesions, and work up can be tricky.2Background: A 60-year-old man was admitted mid-January 2020 for acute left abdominal pain. He had no medical history and didn’t smoke or take any medication. He had no history of recent trauma...

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 Adrenal Insufficiency (PAI or Addison’s disease) is a rare disease with an increasing prevalence that may be complicated by life-threatening acute adrenal crisis. Valid epidemiological data are difficult to obtain. In Belgium, a national PAI registry had not been established yet.Objective: We collected epidemiological and clinical data in a large cohort of adult patients with a known Addison’s disease to have a better know...
