JF Thorax JO Thorax FD BMJ Publishing Group Ltd and British Thoracic Society SP 356 OP 360 DO 10.1136/thx.31.3.356 VO 31 IS 3 A1 J G Stephen A1 M V Braimbridge A1 B Corrin A1 S P Wilkinson A1 D Day A1 W F Whimster YR 1976 UL http://thorax.bmj.com/content/31/3/356.abstract AB A case of necrotizing sarcoid angiitis and granulomatosis (NSG) presenting as a peripheral lung 'tumour' in a 63-year-old man is recorded, and the clinical and pathological features are compared with those of Liebow's original cases. Resection may be avoided if the diagnosis is made by biopsy as the disease is possibly steroid responsive and the prognosis appears favourable. The aetiology is obscure but an immune disturbance is suspected.
