Dupuytren's subungual exostosis is an uncommon osteochondral lesion affecting the distal phalanx of adolescents. Lack of awareness of this unusual lesion causes many to be initially misdiagnosed. Accurate diagnosis based on clinical findings and radiographs and appropriate treatment methods are outlined. We report retrospectively on the cases of six children treated for subungual exostosis over a 3-year period. Diagnosis was made based on clinical findings of a painful subungual or periungual mass associated with an exostosis on radiographs. Complete excision of the lesion, including the overlying nailbed, was curative in the five patients who opted for surgical treatment. Two of our patients had been previously treated with an incomplete excision and had a recurrence within 3 months of the original procedure. Failure to recognize and treat this condition appropriately may lead to morbidity due to overtreatment or recurrence. We hope this report will improve awareness of subungual exostosis and the appropriate operative treatment method.
杜普伊特伦氏甲下外生骨疣是一种罕见的骨软骨病变，影响青少年的远节指骨。由于对这种不寻常病变缺乏认识，许多患者最初会被误诊。本文概述了基于临床发现和X线片的准确诊断以及适当的治疗方法。我们回顾性报告了3年间6例接受甲下外生骨疣治疗的儿童病例。诊断基于临床发现的甲下或甲周疼痛性肿块以及X线片上显示的外生骨疣。对于选择手术治疗的5例患者，完整切除病变（包括覆盖的甲床）可治愈。我们的2例患者此前接受了不完全切除，在原手术3个月内复发。未能正确认识和治疗这种疾病可能因过度治疗或复发而导致发病。我们希望本报告能提高对甲下外生骨疣及适当手术治疗方法的认识。
