A Case of Sarecoid Dactylitis / 대한피부과학회지

ABSTRACT

We report a case of sarcoid dactylitis in which there have been significant bone changes. A 46 year-old female presented with digital erythematous clubbing-like changes and sausage-like swellings of middle phalanges of both hands for 3 months. She had also several freely movable nontender subcutaneous nodules on her trunk and extremities for 3 years. There was a mild leukopenia and decreased cell-mediated immunity. The chest X-ray revealed bilateral hilar lymphadenopathy with increased interstitial lung markings. The X-ray of the hands and feet revealed paraarticular osteolytic lesions and altered trabecular patterns. Histopathologically there were several well-circumscribed granulomas without any caseating necrosis. We treated her with oral prednisone and hydroxychloroquine with some improvement.
