Abstract
We present a case of a 76-year-old Caucasian female with a recurrent solitary fibrous tumor (SFT) of the pleura, showcasing a rare manifestation of hypoglycemia associated with Doege-Potter syndrome (DPS). Having undergone two previous surgeries for SFT, the patient presented to the emergency department with severe fatigue, recurrent episodes of loss of consciousness, and hypoglycemia, despite lacking a history of diabetes mellitus. Radiological evaluation revealed a substantial recurrent SFT in the left lung, prompting excision through a left posterolateral thoracotomy. Remarkably, the patient's altered mental status and hypoglycemia resolved postoperatively. The case meets the criteria for aggressive SFT behavior, warranting consideration for adjuvant radiation therapy to control the risk of recurrence. This report highlights the nuanced interplay between SFT recurrence, paraneoplastic syndromes like DPS, and the potential benefits of adjuvant therapeutic strategies in managing these complex clinical scenarios.
