HIGH-FREQUENCY ULTRASOUND SCAN FOR NONINVASIVE CROSS-SECTIONAL IMAGING OF PSORIASIS

Seventeen patients with psoriasis vulgaris were studied by high-freque ncy (20 MHz) ultrasound imaging. An echo-lucent band located at the de rmo-epidermal junction was characteristic. The band represents the com bination of acanthotic epidermal thickening and inflammation. Thus, wi th ultrasound the site within the skin where primary events take place can be studied and followed non-invasively, i.e. with no known distur bance and influence on the course of the disease.
