Abstract

Psoriatic onycho-pachydermo-periostitis (POPP) causes severe nail dystrophy, painful soft tissue swelling, and marked periosteal reaction of the involved distal phalanx. There are few reports of POPP involving the great toe. We report on 2 cases of POPP involving the fingertips. A 60-year-old woman presented with fusiform swelling of her right 4th fingertip with severe tenderness, and her fingernails and toenails had varying degrees of onycholysis. She had mixed multiple erosions and meta-epiphyseal periostitis at the distal phalanx of the right 4th finger but was treated successfully with methotrexate and cyclosporine. A 39-year-old woman presented with painful swelling of the left 2nd and 5th fingertip, psoriatic lesions on the knees and soles of the feet, and onycholysis without reactive periostitis of the left 2nd and 5th fingers. She was treated successfully with cyclosporine. Despite its rarity, POPP should be considered when diagnosing arthritic or infectious conditions affecting the distal interphalangeal joint.
