Pneumococcal bacteremia diagnosed by peripheral blood smear in multiple myeloma.
A patient with multiple myeloma and a normal spleen died with high-grade pneumococcal bacteremia diagnosed by routine examination of a Wright-stained peripheral blood smear. In earlier reports, this finding has been described only in patients with abnormal or absent spleens. We review the proposed mechanisms of high-grade pneumococcal bacteremia in these patients and the immunologic abnormalities in patients with multiple myeloma that may result in increased susceptibility to this infection.
