[Adenocarcinomatous pleural lesion associated with hypoglycemia]

We report the case of a patient suffering from a glandular pleural lesion. The evolution of the disease was punctuated by periods of hypoglycaemia, which caused a coma. There was no clinically evident explanation for these hypoglycaemic episodes. Investigations revealed adrenal failure, but this adrenal failure was unrelated to the neoplastic process in the patient. This case is a reminder that the cause of hypoglycaemia associated with tumours can really have a paraneoplastic origin and justifies an in depth study to achieve an aetiological diagnosis.
