High‐Frequency Ultrasound in Blistering Skin Diseases: A Useful Method for Differentiating Blister Locations

摘要

Bullous pemphigoid and pemphigus vulgaris, which belong to the group of subepidermal and intraepidermal bullae, respectively, are two potentially devastating blistering skin diseases. We used high‐frequency ultrasound (US) in 3 cases of these diseases as prototypes to study the value of high‐frequency US in discriminating blister locations. Our findings showed that high‐frequency US has a strong correlation with histomorphometric findings because of its high resolution, and we hope that it will be helpful for differentiating blister locations.
