目的探讨I期压疮“非漂白性红斑”的皮肤镜表现及特点。方法皮肤镜检查使用DermLite (R) II检查骨突出部位的红肿，在减压30分钟内未解决或如果3天内无法改变位置。结果ⅰ期压疮的典型皮肤镜表现为斑点状斑点和毛细血管扩张条纹，其他变色因血管扩张而消失。这些皮肤镜特征在10例中有9例可见。其中一例，在皮肤镜压迫下观察到紫癜持续存在。同样，在3例II期压疮周围发红的病例中，发现了点状斑点和毛细血管扩张条纹。结论压疮的“非漂白性红斑”由皮肤镜压迫后持续存在的斑点、毛细血管扩张条纹和紫癜组成，这些特征有助于皮肤镜诊断压疮。
Objective To assess dermoscopic findings of "non-blanchable erythema" in stage I pressure ulcers and to determine their characteristics.Methods Dermoscopic examinations using DermLite (R) II pro of redness over a bony prominence that did not resolve within 30 min of pressure relief or if a positional change was impossible for three days.Results Characteristic dermoscopic findings of redness in stage I pressure ulcers included petechial dots and telangiectatic streaks while other discolorations disappeared by diascopy. These dermoscopic features were seen in 9 of 10 cases. In one case, purpura that persisted under dermoscope compression was observed. Likewise, petechial dots and telangiectatic streaks were detected in three cases with redness surrounding stage II pressure ulcers.Conclusion The "non-blanchable erythema" in pressure ulcers consists of petechial dots, telangiectatic streaks and purpura that persist after compression by the dermoscope and these characteristics are helpful for dermoscopically diagnosing pressure ulcers.
