High-frequency ultrasonography: one of the modern imaging diagnostic methods in dermatology. Authors' own experience and review.

Introduction: High-frequency ultrasonography (HFUS) has emerged as a non-invasive and cost-effective diagnostic tool for evaluating the outcomes of dermatological therapeutic procedures.

Aim: This manuscript presents a comprehensive collection of sonographic images depicting cutaneous lesions associated with various dermatoses, including verruca vulgaris, epidermoid cyst, maculopapular cutaneous mastocytosis and lichen sclerosus et atrophicus.

Material and methods: Drawing from an extensive review of the existing literature and supported by empirical observations, the study highlights key sonographic attributes observable in both normal and pathological skin variants.

Results: It has been demonstrated that individual skin lesions exhibit distinct characteristics on HFUS. Furthermore, ultrasonographic examination has proven to be valuable for the objective assessment of disease severity.

Conclusions: Additionally, the study contributes to a deeper understanding of HFUS as a valuable tool in dermatological diagnostics.
