A 54-year-old woman presented with painless subcutaneous masses on her right hand and spontaneous loss of extension of her ring finger. Surgical exploration of the wrist showed hypertrophic white-colored crystal deposits that both surrounded and invaded into the extensor tendons (intratendinous invasion). Histopathologic examination of the specimen demonstrated findings consistent with gouty tophi. We conclude that tophaceous gout needs to be included in the differential diagnosis of chronic extensor tenosynovitis of the hand.
一位 54 岁女性因右手无痛性皮下肿块和无名指自发性伸展丧失而就诊。腕部手术探查显示增生的白色结晶沉积物，既环绕又侵入伸肌腱（肌腱内侵袭）。标本的组织病理学检查显示符合痛风石的发现。我们的结论是，痛风石性痛风需要纳入手部慢性伸肌腱滑膜炎的鉴别诊断。
