Refractory hypoglycemia associated with giant solitary fibrous tumor of the pleura (Doege–Potter syndrome)

Background: The association of a solitary tumor of the pleura with paraneoplastic refractory hypoglycemia is a very rare clinical condition. Methods: An 86-year-old gentleman with an incidentally discovered large mass in the left chest and a long-standing history of refractory hypoglycemia was referred for surgical consultation. Computed tomography and PET (Positron Emission Tomography) scan confirmed the presence of a homogeneous mass leaning on the left hemidiaphragm with no tracer uptake. Results: After tumor board discussion, the mass was radically excised through a left thoracotomy. Histopathology revealed a benign solitary fibrous tumor of the pleura. At 1‑year follow-up the patient was doing well and did not further complain of hypoglycemia-related symptoms. Conclusion: Doege–Potter syndrome is a life-threatening condition associated with severely impaired quality of life. Prompt identification and surgical treatment are mandatory.
