A case report of non-islet cell tumour hypoglycaemia associated with ovarian germ-cell tumour

Abstract

Background:

Non-islet cell tumour hypoglycaemia is a rare paraneoplastic condition in which tumours secrete a high-molecular-weight precursor of insulin-like growth factor-II causing hypoglycaemia and can be difficult to identify and treat.

Case Presentation:

This is the case of a 27-year-old patient from Africa with metastatic ovarian yolk sac tumour who presented with hypoglycaemia and was subsequently diagnosed with non-islet cell tumour hypoglycaemia.

Case Management:

Our patient required higher doses of glucocorticosteroids than reported in the literature in combination with recombinant growth hormone therapy in order to control her hypoglycaemia.

Case Outcome:

This is the first case of non-islet cell tumour hypoglycaemia described in association with a germ-cell tumour. Her management required collaboration between the endocrinology team, the palliative care team, the acute medicine team and physicians in Africa to enable her safe journey home.

Conclusions:

This case illustrates the need for awareness among general physicians of rare tumour manifestations and the need for multidisciplinary input for the optimal management of these patients.
