摘　　要：BACKGROUND Sarcoidosis is a multisystem disease characterized by granuloma formation in various organs.Sarcoidosis-related flexor tendon contractures are uncommon in clinical settings.This contracture is similar to stenosing tenosynovitis and po-tentially leads to misdiagnosis and mistreatment.Herein,we report a rare case of sarcoidosis-related finger flexor tendon contracture that was misdiagnosed as tenosynovitis.A 44-year-old woman presented to our department with flexion contracture of the right ring and middle fingers.The patient was misdiagnosed with tenosynovitis and underwent acupotomy release of the A1 pulley of the middle finger in an-other hospital that resulted in iatrogenic rupture of both the superficial and profundus flexors.Radiological presentation showed multiple sarcoid involve-ments in the pulmonary locations and ipsilateral forearm.A diagnosis of sar-coidosis was made based on the presence of non-caseating granulomas with tubercles consisting of Langhans giant cells with lymphocyte infiltration on biopsy,and the patient underwent surgical repair for the contracture.After 2 mo,the patient experienced another spontaneous rupture of the repaired middle finger tendon and underwent surgical re-repair.Satisfactory results were achieved at the 10 mo follow-up after reoperation.CONCLUSION Sarcoidosis-related finger contractures are rare;thus,caution should be exercised when dealing with such patients to avoid incorrect treatment.
