title: [Psoriatic onycho-pachydermo- periostitis].
abstract: We report about a patient with a 2 year history of palmo-plantar psoriasis and psoriatic involvement of the nails. Within six months he developed a psoriatic onychodystrophy and painful swellings of the toes and fingers. X-rays revealed acral lamellar periostitis. The case of this patient represents a rare variety of psoriatic arthritis: The psoriatic onycho-pachydermo-periostitis. After a 6 week therapy with methotrexate (15mg per week) the nails began to grow regularly. Therefore, in cases of psoriasis with unusual symptoms of psoriatic arthritis the psoriatic onycho-pachydermo-periostitis should be included in differential diagnosis and therapy.
