ABSTRACT:		We have described the first patient to be reported in whom plasma prekallikrein (Fletcher factor) deficiency and chronic lymphocytic leukemia were both present. This most likely represents a coincidental occurrence, but the markedly elevated peripheral blood lymphocyte count and the detection of the defect using ellagic acid are unique for Fletcher factor deficiency.
