Dactylitis and bone lesions at the onset of sarcoidosis: a case report.

Dactylitis and bone lesions are rare complications of sarcoidosis that occur in the chronic disease and they are unusual features of the disease at presentation. The present paper describes a case of a 28-year-old woman with dactylitis (due to tenosynovitis and soft tissue granulomas) and phalangeal bone lesions in 2 fingers at the onset of sarcoidosis. She also had asymptomatic pulmonary type I sarcoidosis (bihilar lymph node enlargement with no involvement of the lung parenchyma). The response to treatment (prednisone 30 mg/day, tapered to 5 mg over 2 months for a 12-month period) was very good, with no relapse at 6 months after the end of systemic treatment.
