Pleural-based giant solitary fibrous tumour with associated hypoglycaemia: unusual presentation with pulmonary hypertension in a patient with Doege-Potter syndrome.

Refractory hypoglycaemia in a patient with a solitary fibrous tumour (SFT) is very rare and was first reported in 1930 independently by Doege and Potter, leading to it being named 'Doege-Potter syndrome'. Here, we report the unusual case of a 77-year-old woman with a giant solitary fibrous pleural tumour who presented with complicating pulmonary hypertension and associated heart failure with hypoglycaemia, and subsequently underwent curative resection of the pleural mass with clinical improvement.
