Psoriatic-onycho-pachydermo-periostitis, a rare psoriatic arthropathy, involves nail changes, soft tissue thickening, and bone inflammation without joint damage. This case report details the first instance affecting all fingers and toes.

Area of Science:

  • Rheumatology
  • Dermatology
  • Radiology

Background:

  • Psoriatic arthropathy encompasses diverse musculoskeletal manifestations associated with psoriasis.
  • Psoriatic-onycho-pachydermo-periostitis (POPP) is a recently identified subtype characterized by specific clinical and radiological features.

Observation:

  • This report describes two cases of POPP.
  • The first case presented with POPP affecting all fingers and toes, a comprehensive presentation.
  • Clinical examination revealed psoriatic onychosis, distal soft tissue hypertrophy, and distal phalanx osteo-periostitis.

Findings:

  • Biological examinations in POPP are typically normal.
  • Radiological findings include phalanx condensation with a characteristic spicule-like appearance.

Related Experiment Videos

  • The absence of interphalangeal joint lesions is a key diagnostic feature.

    • Implications:

    • This case expands the understanding of POPP's clinical spectrum.
    • Early recognition of POPP is crucial for appropriate management of psoriatic arthropathy.
    • Further research is warranted to elucidate the pathogenesis and optimal treatment strategies for POPP.
