SYNOPSIS Necrotizing arteritis with giant cells, involving the aorta, pulmonary and coronary arteries, and coronary, splenic, and renal arterioles was found at necropsy in a 74-year-old male who had died with severe haemolytic anaemia associated with cold haemagglutinins.The clinical and pathological features of this case are shared by well-recognized forms of necrotizing angiitis, in particular giant cell arteritis, but do not conform satisfactorily with any of these disorders. Cold agglutinin haemolytic anaemia in this instance suggests the possibilitv of an autoimmune aetiology.The absence of a completely satisfactory classification of the various forms of necrotizing angiitis reflects the considerable overlap of clinical and pathological features among these conditions. This report of a patient whose features were not typical of any one syndrome gives weight to the concept that the various forms of necrotizing angiitis are a spectrum of vascular disease which includes giant cell arteritis, Wegener's granulomatosis, the ChurgStrauss (1951) syndrome, and polyarteritis nodosa.
CASE REPORTA 74-year-old man entered hospital on 20 April 1963, because of jaundice of one day's duration. He had had chronic cough with sputum and exertional dyspnoea for many years. He had experienced gradual loss of vision of the left eye and left parotid swelling four months before admission. The parotid swelling subsided slowly and spontaneously. One month later he had increasing shortness of breath and a right pleural effusion. Thrombophlebitis developed in the right calf a week later. The thrombophlebitis resolved following penicillin, tetracycline, and anticoagulant therapy.When he was admitted, fundal examination showed left optic atrophy. He was severely anaemic (Hb 6-9 g. per 100 ml. to a titre of 1/512 at 4°C., and 1/32 at 20°C.; there was no agglutination at 37°C., but there was a positive direct antiglobulin test at this temperature. There was no Donath-Landsteiner antibody present. Thrombotest (Owren) showed 11-5% coagulation activity. Plasma protein was 5-8 g. per 100 ml. On paper strip plasma protein electrophoresis, there were two haptoglobin bands, an intense band with the beta-globulins and a less intense one with the alpha-globulins.Hyland screening tests for lupus erythematosus, thyroiditis, and rheumatoid arthritis were each negative. Immuno-chemical studies to identify further the cold haemagglutinin were not done nor was it possible to ascertain any blood group specificity.Serum bilirubin was 3-4 mg. per 100 ml.; alkaline phosphatase, 15 King-Armstrong units per 100 ml.; serum glutamic-pyruvic transaminase, 10 Sigma-Frankel units per 100 ml.; urea 51 mg. per 100 ml. Urine analysis was normal.The patient had progressive severe respiratory distress and died 36 hours after admission to hospital.
NECROPSYBoth upper lobes of the lungs were studded with emphysematous blebs and cysts. The lower lobes were wet, heavy, and speckled with many small collections of pus. There was 30 ml. of clear pericardial effusion. The myoc...
