Abstract
We report a severe case of chronic recurrent multifocal osteomyelitis (CRMO) associated with total myeloperoxidase (MPO) deficiency. The etiology of CRMO is in most cases unknown, and this is to our knowledge the first case associated with MPO-deficiency. Leukocyte MPO-deficiency renders neutrophils unable to process superoxide to secondary reactive oxygen species (ROS). Partial MPO deficiency is seldom associated with pathology but little is known about the effects of total MPO deficiency.
