Granulomatous pyoderma preceding chronic recurrent multifocal osteomyelitis triggered by vaccinations in a two-year-old boy: a case report
Chronic recurrent multifocal osteomyelitis is a rare, systemic, aseptic, inflammatory disorder that involves different sites. Pathogenesis of chronic recurrent multifocal osteomyelitis is currently unknown. A two-year-old Caucasian boy, diagnosed with chronic recurrent multifocal osteomyelitis with granulomatous pyoderma following routine vaccinations is presented for the first time in the literature. We conclude that antigen exposures might have provoked this inflammatory condition for our case. Skin and/or bone lesions following vaccinations should raise suspicion of an inflammatory response such as chronic recurrent multifocal osteomyelitis only after thorough evaluation for chronic infection, autoimmune, immunodeficiency or vasculitic diseases.
