We describe the case of a 53-year-old man who presented with abdominal pain, diarrhoea and hypomagnesaemia. The hypomagnesaemia proved to be due to gastrointestinal loss as urinary fractional excretion was very low, suggesting non-renal loss. Common causes were discarded and the hypomagnesaemia was attributed to chronic use of the proton pump inhibitor, omeprazole. As such, omeprazole was discontinued and an H2 blocker was given. Several days later the patient presented with upper gastrointestinal bleeding. CT scan demonstrated marked enlargement of the duodenum and proximal jejunum, and abnormal thickening and enhancement of the bowel wall. Urgent oesophagogastroduodenoscopy revealed coffee-ground and bloody contents in the distal oesophagus and stomach, and numerous ulcers along the duodenum and jejunum. A positron emission tomography-CT scan using GA 68-DOTANOC demonstrated increased uptake in the gastroduodenum junction, suggesting a neuroendocrine tumour. Pancreaticoduodenectomy was performed and tumour cells stained positive for gastrin, confirming the tentative diagnosis of Zollinger-Ellison syndrome., (2014 BMJ Publishing Group Ltd.)

A 44-year-old woman diagnosed with dermatomyositis 5 years ago based on progressive proximal muscle weakness, elevated creatine kinase, typical findings on electromyography and muscle biopsy. Despite the treatment, in contrast to improvement in her muscle symptoms, the heliotrope rash of her eyelids persisted. After several years, the patient developed multiple limited skin retraction lesions with hyperpigmentation on both lower limbs. Palpation of these lesions revealed dry, cold and very firm skin on both thighs and calves, particularly in the distal areas. X-ray and ultrasound imaging of the calves showed multiple subcutaneous calcifications in the distal muscles., (2014 BMJ Publishing Group Ltd.)

We report a case of a 54-year-old woman presented with bilateral pitting leg oedema. Initial workup for common aetiologies was unrevealing and diuretic therapy was ineffective. A CT scan of the abdomen demonstrated left adrenal mass with direct invasion of the adrenal vein and inferior vena cava with direct extension to the right atrium. Adrenocortical carcinoma was confirmed in biopsy and the patient was operated within several days. Fifteen months postoperation, the patient is doing well with good performance status and still in oncological treatment and follow-up. When the common causes of bilateral oedema have been ruled out, no delay should be experienced seeking abdominal mass with vascular invasion potential, as early diagnosis and treatment may be lifesaving.
