CONCOMITANT OCCURRENCE OF PSORIATIC-ARTHR ITIS AND RECURRENT MULTIFOCAL OSTEOMYELITIS - REPORT OF A CASE

A 13-year-old developed psoriatic arthritis and recurrent multifocal o steomyelitis. The latter is an inflammatory disease involving multiple skeletal sites, whose diagnosis rests on suggestive physical findings , laboratory evidence of inflammation, and characteristic histological changes with negative biopsy specimen cultures. There is almost gener al agreement that anti-inflammatory agents are useful in recurrent mul tifocal osteomyelitis, whereas the need for antimicrobials is under de bate. Spontaneous remissions have been reported. The simultaneous occu rrence of psoriatic arthritis in the case reported herein suggests tha t the two diseases may share one or more pathogenic factors.
