Paraneoplastic Hypoglycaemia in a Patient With Solitary Fibrous Tumor of Pleura

Solitary fibrous tumours (SFTs) are rare spindle cell neoplasms, predominantly benign, comprising less than 2% of all soft tissue masses. In rare cases, SFTs can lead to Doege-Potter syndrome, a paraneoplastic condition characterised by hypoglycaemia due to elevated levels of insulin-like growth factor II (IGF-II). Patients typically present with symptomatic hypoglycaemia related to this hormonal dysregulation. We report the case of a 70-year-old man who presented with weight loss, cough, fatigue, tingling, and episodes of confusion associated with recurrent hypoglycaemia. Chest radiography revealed a large soft tissue mass in the right lower hemithorax, and CT-guided biopsy confirmed tumour infiltration in the basal segment of the right lower lobe.
