Fibrosarcoma of the lung with extrapulmonary manifestations: case report

A 50-year-old female presented with a five months history of recurrent attacks of dizziness, sweatiness, tremors and fainting with loss of consciousness. These were found to be due to hypoglycaemic episodes with blood sugars less than 1 mmol/l and were treated as such. A diagnosis of insulinoma was initially considered, but the patient turned out to have fibrosarcoma of the lung, a rare lung tumour. She also had finger and toe clubbing and features of hypertrophic pulmonary osteoarthropathy.
