Peptide receptor radionuclide therapy for ectopic Cushing's syndrome caused by metastatic neuroendocrine neoplasms.

Background: Metastatic gastroenteropancreatic neuroendocrine neoplasms (GEPNEN) can cause ectopic Cushing's syndrome (ECS). ECS is highly morbid and medical therapy is complex and can be ineffective. Patients unsuitable for bilateral adrenalectomy (BA) have dismal outcomes.

Metanephrine mirage: distinguishing the phaeocopies, a case report and literature review.

Background: We present one of only seven reported cases of a catecholamine-secreting adrenal neuroblastoma in an adult. The case is used as a platform to discuss key biochemical, genomic and imaging considerations that are central to the successful, targeted management of catecholamine-secreting adrenal tumours.

Case Presentation: A 63-year-old male was urgently reviewed at a tertiary hospital endocrinology outpatient clinic for a 12 cm right-sided adrenal incidentaloma.

Real-life effects of pharmacological osteoporosis treatments on bone mineral density by quantitative computed tomography.

Introduction: Monitoring of bone mineral density (BMD) is used to assess pharmacological osteoporosis therapy. This study examined the real-life effects of antiresorptive and osteoanabolic treatments on volumetric BMD (vBMD) of the spine by quantitative computed tomography (QCT).

Materials And Methods: Patients aged ≥ 50 years with a vBMD < 120 mg/ml had ≥ 2 QCT.

Recent progress in molecular classification of phaeochromocytoma and paraganglioma.

Phaeochromocytomas (PC) and paragangliomas (PG) are neural crest cancers with high heritability. Recent advances in molecular profiling, including multi-omics and single cell genomics has identified up to seven distinct molecular subtypes. These subtypes are defined by mutations involving hypoxia-inducible factors (HIFs), Krebs cycle, kinase and WNT signalling, but are also defined by chromaffin differentiation states.
