Human skin histology using high‐resolution echography

Abstract

Normal and abnormal human skin echograms were made using new 25‐MHz and 40‐MHz ultrasonic sector scanners, and were compared with histologic sections. The malpighian layer of the epidermis was demonstrated as an echolucent zone under a strongly echogenic, linear corneo‐malpighian junction in normal palms and soles. Cross sections and longitudinal sections of hair follicles and hypertrophic sebaceous glands were also demonstrated as echolucent structures.
