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 30min 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.
