A 32-year-old woman presented with a three months' history of a hard painless swelling of the bridge of the nose (Fig. 1) but no skin lesions or lymphadenopathy. Biopsy showed bony spicules and giant cell systems without evidence of caseation, i.e. appearances consistent with Boeck's sarcoidosis. Bacteriological examination showed no evidence of M. tuberculosis directly or on culture. Laboratory tests. Haemoglobin 87 per cent; white cell count 7,100 per cu. mm; normal differential WBC.; blood urea 13 mg per cent; electrolytes—normal; liver function tests—normal; serum calcium 9·8 mg per cent; 24-hour excretion of calcium = 242 mg (normal); alkaline phosphatase four units; Wassermann reaction—negative; Rose-Waaler test—negative; serum proteins 8·2 g per cent with increase ...
