Prurigo Nodularis at Ultra-High-Frequency Ultrasound.

Here, we describe the case of a 48-year-old female patient with prurigo nodularis, where B-mode and color-Doppler ultrasound of one nodule was performed; this revealed hypoechoic dermal and hyperechoic epidermal thickening with lesion hypervascularity. To the best of our knowledge, no previous published articles have reported ultra-high-frequency ultrasound images of this disease, so this case can encourage prurigo nodularis studies in order to better assess ultrasound features and their usefulness in supporting clinical diagnosis and in distinguishing prurigo nodularis from other diseases.
