BACKGROUND: Solitary fibrous tumors of the pleura (SFTPs) are relatively rare 
tumors that originate from mesenchymal cells of submesothelial tissue of the 
pleura. Most patients with SFTPs are asymptomatic; however, pleuritic chest 
pain, cough, and dyspnea can develop. If hypoglycemia is associated with a 
solitary fibrous tumor, it is referred to as the Doege-Potter syndrome.
CASE PRESENTATION: A 70-year-old man had visited our hospital with a chief 
complaint of dyspnea, and he was diagnosed as having a solitary fibrous tumor. A 
few years later, he developed hypoglycemia, and he underwent excision of the 
mass.
CONCLUSION: Occasionally, SFTPs induce several paraneoplastic events, such as 
hypertrophic osteoarthropathy. We described here a patient with an SFTP with 
Doege-Potter syndrome who was successfully treated with complete resection. 
Although lesions can be histologically benign, they can clinically present with 
malignant features.
