隆突性皮肤纤维肉瘤7例误诊分析

Misdiagnosis of Dermatofibrosarcoma Protuberans: Analysis of 7 Cases

目的提高对易误诊隆突性皮肤纤维肉瘤病例的认识,减少对隆突性皮肤纤维肉瘤的误诊。方法回顾性分析7例曾被误诊的隆突性皮肤纤维肉瘤病例临床表现及误诊情况,分析误诊原因。结果 7例患者临床表现均不典型,曾分别被误诊为瘢痕疙瘩、皮肤纤维瘤、表皮囊肿、神经鞘瘤。误诊时间1年~25年。结论隆突性皮肤纤维肉瘤临床少见,易于误诊,提高对隆突性皮肤纤维肉瘤的认识及警惕性有助于确诊及减少临床误诊。

Objective To improve the awareness of misdiagnosis of dermatofibrosarcoma protuberans, and reduce the rate of its misdiagnosis. Methods Clinical manifestations, misdiagnosis and its causes were retrospectively analyzed in 7 cases of misdiagnosed dermatofibrosarcoma protuberans. Results These 7 patients were misdiagnosed as keloid, skin fibroma, epidermal cysts, and neurilemmoma due to its atypical clinical manifestations. The accurate diagnoses were delayed for 1 to 25 years. Conclusion Dermatofibrosarcoma protuberans is rare and can be easily misdiagnosed. Improvement of awareness and alertness of this disorder would be helpful to avoid its misdiagnosis.
