Hypoglycaemia caused by secretion of insulin-like growth factor 2 in a primary renal cell carcinoma.

Non-islet cell tumour hypoplycaemia (NICTH) due to the production of an aberrant form of insulin-like growth factor 2 (IGF 2) is a well-recognised phenomenon. This is the first formally reported case occurring in an adult with a primary renal cell carcinoma. This case report describes in detail the various treatment modalities that were used in an attempt to palliate this patient's severe hypoglycaemia.
