Purpose: This review aims to highlight the increasing role of ultrasound in dermatology, emphasizing its utility in assessing skin and nail lesions. It focuses on the technological advancements and research driving its adoption as a safe, cost-effective, and non-invasive diagnostic tool.

Methods: We conducted a comprehensive review of the literature, focusing on the technical aspects of dermatologic ultrasound, including real-time visualization, color Doppler for vascularity detection, and high axial spatial resolution. The ultrasonographic patterns of common benign and malignant conditions, inflammatory diseases, vascular anomalies, and nail lesions were analyzed.

Results: Ultrasound provides detailed real-time imaging, enabling accurate diagnosis and treatment planning for various dermatologic conditions. Key findings include the identification of characteristic ultrasonographic patterns for skin neoplasms, inflammatory diseases, and vascular malformations, as well as its efficacy in evaluating nail lesions.

Conclusions: Dermatologic ultrasound is a valuable tool for early diagnosis and management of skin and nail conditions. Its ability to visualize structural and vascular features in real-time improves diagnostic accuracy, making it an essential addition to dermatologic practice. Knowledge of ultrasonographic patterns can significantly benefit patient care.
