Pneumococcal bacteremia as the initial presentation of multiple myeloma – a case report
Keywords:
Multiple Myeloma, Pneumococcemia, Streptococcus pneumoniaeAbstract
Multiple Myeloma (MM) accounts for approximately one percent
of all cancers and is characterized by the neoplastic proliferation of a single clone of plasma cells producing a monoclonal
immunoglobulin.
Clinical features are anemia, bone pain, renal failure and hypercalcemia. Rarely, a bacterial infection is the initial presentation
of this disease.
We report a case in which bacteremia caused by Streptococcus
pneumoniae, possibly associated to Septic Arthritis (SA), was the
initial presentation of multiple myeloma. This situation has been
seldom reported in medical literature.
Association between pneumococcal infection and a specific
predisposing disease is common. Pneumococcal infection should
lead to a suspicion of underlying illness and the co-existence
of other diseases must be ruled out in the diagnosis, namely
multiple myeloma.
