The occurrence of hypoglycemia with an intrathoracic tumor is referred to as Doege- Potter syndrome (DPS). However, the association between hypokalemia and DPS is rare. We report a case of a solitary fibrous tumor of the pleura with refractory hypoglycemia and hypokalemia. A 57-year-old male was admitted to our hospital for unconsciousness. His serum glucose and potassium levels were low. Radiological findings revealed a large tumor occupying the left hemithorax. Despite being treated with glucose and potassium replacement therapy, the patient still suffered from repetitive fasting hypoglycemic and hypokalemia episodes. After the tumor was completely resected, his serum levels of glucose and potassium returned to normal level.
