title: [Psoriatic onycho-pachydermo- periostitis].
abstract: BACKGROUND
  Psoriatic onycho-pachydermo-periostitis is a rare manifestation of psoriatic arthritis. It is characterized by the trias of psoriatic onychosis, tender soft tissue thickening, and osteoperiostitis of the distal phalanges in the absence of distal interphalangeal arthritis. Recommendations for the treatment of symptomatic POPP are not available.
  
  
  OBJECTIVE
  Treatment of a symptomatic 49-year old male.
  
  
  METHODS
  Sulfasalazine 1000mg b.i.d., p.o. for 8 months followed by radiotherapy of both hands with 6x0.5 Gy.
  
  
  RESULTS
  No clinical response was observed with either of the two treatments.
  
  
  CONCLUSIONS
  The course of this single case does not support sulfasalazine treatment or radiotherapy in psoriatic onycho-pachydermo-periostitis.
