- Abstract
Objective To assess dermoscopic findings of 'non-blanchable erythema' in stage I pressure ulcers and to determine their characteristics. Methods Dermoscopic examinations using DermLite® 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.
