Managing hyponatraemia in a patient with malignant melanoma: a case report

摘要

We report the case of a 46-year-old male with a known diagnosis of metastatic malignant melanoma who presented with hyponatraemia. The report details the challenges we faced in identifying the cause of his hyponatraemia and in attempting to reverse his electrolyte disturbance. As his clinical condition deteriorated the focus of our management needed to change; recognising that he was dying we implemented the Mental Capacity Act to make decisions in his best interest and ensure he achieved a symptom controlled and dignified death.
