-To provide basic knowledge on the key sonographic signs for diagnosing lesions of the nail and periungual region  

Nail sonography has emerged as a diagnostic tool for studying lesions of the nail. This imaging technique provides detailed anatomical information on the echostructure, dimensions, location and blood flow of nail conditions. This educational exhibit is composed of the technical requirements, the examination technique, the normal anatomy and 20 cases of histologically proven lesions of the nail. The lesions are classified according to their origin, into ungual and periungual. Location and growth alterations (i.e. onychocryptosis, onychomadesis, retronychia), inflammatory diseases (i.e. psoriasis, subungual fluid collections, median canaliform dystrophy), tumors and pseudotumors (i.e. glomus tumor, fibrous tumor, onychomatricoma, granuloma, wart, myxoid cyst and subungual exostosis) are demonstrated.The key sonographic signs are illustrated through drawings, and clinical, sonographic, surgical and histological images. Summary Nail sonography can provide valuable anatomical information for the clinician. Knowledge of the key sonographic signs in lesions of the nail may facilitate the performance and interpretation of ungual sonographic examinations.
