Background: Solitary fibrous tumor of the pleura is a rare primary intrathoracic tumor that arises from mesenchymal tissue. Hypoglycemia associated Solitary fibrous tumor of the pleura is referred to as the Doege-Potter syndrome and is caused by inappropriate secretion of an insulin-like growth factor II.

Case presentation: We report 70-year-old women with no particular medical history, who present a right chest pain for 1 year with fatigue. The clinical examination revealed diminished breath sounds in right lung fields, and dullness to percussion. the Lab test showed non-insulin mediated hypoglycemia. Hypoglycemia was managed firstly with corticosteroid therapy and frequent programmed nutritional intake. Scanning demonstrated a right large, well-circumscribed, homogeneous pleural mass. A transthoracic puncture was performed which came back inconclusive. Right posterolateral thoracotomy through the five intercostal space was performed for the resection of the tumor. The histopathologic examination confirmed the presence of malignant Solitary fibrous tumor of the pleura with free marginal resection. Removal of the mass solved the hypoglycemia. The patient was discharged on postoperative day 5.
