Chilblains is a benign condition infrequently encountered in clinical practice; its resemblance to vasculitis or peripheral thromboemboli can often result in an extensive and unnecessary diagnostic work-up.
Three cases of chilblains seen by our Rheumatology service, along with 113 documented cases, were reviewed.
Chilblains is characterized by painful red-to-purple papular lesions involving the acral surface of fingers or toes that resolves with symptomatic treatment. Female sex and low body mass index are risk factors.
Distinct clinical features of chilblains can be used for early recognition and management, thus avoiding unnecessary diagnostic testing and delays in patient care.
冻疮是一种在临床实践中很少见的良性疾病；它与血管炎或周围血栓形成的相似之处，往往会导致广泛而不必要的诊断性检查。
我们的风湿病科诊治了 3 例冻疮患者，并回顾了 113 例已发表的病例。
冻疮的特征是疼痛的红色至紫色丘疹性病变，累及手指或脚趾的远端表面，通过对症治疗可缓解。女性和低体重指数是危险因素。
冻疮的独特临床特征可用于早期识别和管理，从而避免不必要的诊断性检查和延迟患者治疗。
