Abstract

The use of skin ultrasound (US) in dermatology practice has been increasing in the last decades. Thanks to the development of new devices based on high (17–22 MHz) and ultra-high (70–100 MHz) frequencies that allow the visualization of epidermal architecture, dermal, and hypodermal structures reaching the external muscularis fascia. US devices based on medium frequency (5–8 MHz) rest the first choice for emergency department/internal medicine use. A series of skin conditions in which the diagnosis can be challenging from a clinical point of view show peculiar features on US examination: exemplificative cases commonly encountered in dermatological daily practice are discussed here. Using either medium frequency US (MFUS) or high frequency US (HFUS), or both, add several advantages: noninvasive differential diagnosis of these conditions is realized in a fast and not painful way; lesional area can be defined in dimension, content, vascularization, and relationship with surrounding tissues; the effect and efficacy of a specific treatment can be monitored and validated.
