Rapid onset of an additive inflammatory arthritis was observed in a patient with newly-diagnosed carcinoma of the lung. Serological studies revealed antinuclear antibodies and evidence of circulating immune complexes (CIC) by Raji cell assay.

These findings suggest that CIC may not be the cause… CONTINUE READING
