Abstract

BACKGROUND:

Joint and nail involvement in psoriasis is relatively common. In contrast, bony involvement of the terminal phalanx under a psoriatic nail is rare. We report on this psoriatic onycho-pachydermo-periostitis and suggest pathophysiologic mechanisms.

OBSERVATIONS:

Two new cases are reported and the data are compared with the data from eight similar cases reported in the literature. All subjects presented with similar changes--onychopathy, soft-tissue thickening, and radiologic features consisting of bone erosions and a periosteal reaction of the terminal phalanx. Of the 10 patients, two had no history of psoriasis before a diagnosis of psoriatic onycho-pachydermoperiostitis was made. The inflammation is likely transmitted from the psoriatic nail to the adjacent underlying bone by the same mechanism as in enthesopathies.

CONCLUSION:

Psoriatic onycho-pachydermo-periostitis should be recognized as a specific entity in the spectrum of psoriatic disease.
