Polyarticular pneumococcal pyarthrosis in a young haemophiliac.

A case of pneumococcal pyarthrosis involving multiple joints in a moderate haemophiliac is reported. To our knowledge this is the second report of this rare complication in the English literature. Infection should be considered in an acutely inflamed joint in a haemophiliac with hyperpyrexia and unresponsive to replacement therapy. A review of the literature and our observation in this case highlight some criteria that could be used to diagnose this rare but debilitating complication early.
