Doege-Potter syndrome: hypoglycaemic coma in a 90-year old due to a solitary fibrous tumour.

Solitary fibrous tumour of the pleura (SFTP) is a rare primary tumour of the pleura associated with 4% of cases with a paraneoplastic hypoglycaemia, termed Doege-Potter syndrome (DPS). We report a case of DPS presenting with severe coma in a 90-year-old woman. The cause was a malignant SFTP treated with surgical resection, from which the patient made a full recovery with prevention of recurrent hypoglycaemia. Surgical resection of the SFTP presenting with symptomatic hypoglycaemia should be considered even in elderly patients.
