    ObjectivesTo investigate the role of high-resolution ultrasound (HR-US) in the initial and differential diagnosis of the Odontogenic Cutaneous Sinus Tract (OCST) in a multicentric setting.MethodsSkin HR-US examinations of OCSTs performed between January 2019 and June 2023 at different Institutions were retrospectively reviewed. Epidemiological and clinical data (age, gender, location of the skin lesion, causative tooth, and the clinical suspicion) as well as HR-US imaging findings (morphology and length of the sinus tract, Doppler signal, and cortical bone interruption of maxilla or mandible) were collected. US examinations were performed by expert radiologists using a high-performance US scanner, employing a high-frequency linear probe (15 MHz or higher frequencies). In only one patient the HR-US exam was integrated with strain elastography (SE).ResultsSixteen patients were enrolled with a median age of 37.6 years (range 16-70 years). The most frequent clinical suspicion was epidermal cyst, while OCST was suspected in only two cases. In all cases, HR-US depicted the sinus tract as a nodular, triangular or "champignon-shaped" lesion in the subcutaneous layer, which continued with a slightly tortuous band structure, up to the focally interrupted cortical bone plate. Furthermore, color Doppler evaluation showed color signals around and/or within the lesion, expression of inflammation. On SE, the sinus tract showed a hard pattern, due to fibrous and granulomatous tissue.ConclusionsHR-US, thanks to its high spatial resolution, allows the evaluation of OCST, and play a crucial diagnostic role, mainly when the clinical suspicious is different.

    Präoperativer Hochfrequenzultraschall: Ein zuverlässiges Managementinstrument bei nichtmelanozytärem Hautkrebs der Ohrmuschel und der Nase
    (2024) Crisan, Diana; Wortsman, Ximena; Catalano, Orlando; Badea, Radu; Kastler, Sabine; Badea, Alexandru; Manea, Avram; Scharffetter-Kochanek, Karin; Strilciuc, Stefan; Crisan, Maria; Schneider, Lars Alexander
    Hintergrund und ZielsetzungDas Wissen & uuml;ber die Tiefeninfiltration bei nichtmelanozyt & auml;rem Hautkrebs (NMSC) mithilfe pr & auml;operativer Sonographie k & ouml;nnte den & Auml;rzten erm & ouml;glichen, den am besten geeigneten therapeutischen Ansatz zu w & auml;hlen, unn & ouml;tige Operationen und teure bildgebende Verfahren zu vermeiden und die Diagnose und Behandlung nicht zu verz & ouml;gern. In unserer retrospektiven, monozentrischen Studie haben wir die N & uuml;tzlichkeit des Hochfrequenzultraschalls (HFUS) zur Beurteilung der Tiefeninfiltration bei aurikul & auml;ren und nasalen NMSC-F & auml;llen untersucht und die darauffolgende & Auml;nderung des therapeutischen Ansatzes bewertet.Patienten und MethodikIn 60 NMSC-F & auml;llen haben wir die Genauigkeit des HFUS bei der Erkennung von Knorpel- und Knocheninfiltration sowie die Korrelation sonographischer und histologischer Parameter beurteilt.ErgebnisseIn 16,6% der F & auml;lle wurde pr & auml;operativ eine tiefe Knorpel-/Knochenbeteiligung oder eine lokoregionale Erkrankung identifiziert, was zu einer ge & auml;nderten therapeutischen Strategie mit radioimmunologischer Behandlung anstelle von Operation f & uuml;hrte. In zwei F & auml;llen identifizierte der pr & auml;operative HFUS eine lokale Knorpelinfiltration, was die Anzahl der chirurgischen Eingriffe reduzierte. Bei den verbleibenden 48 L & auml;sionen ohne Tiefeninfiltration wurde eine Korrelation von > 99% zwischen der histologischen und sonographischen Tumoreindringtiefe gefunden (p <0.001).SchlussfolgerungenPr & auml;operativer HFUS beeinflusst das therapeutische Vorgehen bei NMSC, indem es eine subklinische Beteiligung tieferer Strukturen erkennt, umfangreichere diagnostische Ma ss nahmen vermeidet, Kosten reduziert und die Qualit & auml;t der Gesundheitsversorgung verbessert. HFUS sollte in der Dermatochirurgie vor der Tumorentfernung zur optimierten Therapie und zur verbesserten Patientenberatung eingesetzt werden.

    Pre-operative high-frequency ultrasound: a reliable management tool in auricular and nasal non-melanoma skin cancer
    (2024) Crisan, Diana; Wortsman, Ximena; Catalano, Orlando; Badea, Radu; Kastler, Sabine; Badea, Alexandru; Manea, Avram; Scharffetter-Kochanek, Karin; Strilciuc, Stefan; Crisan, Maria; Schneider, Lars Alexander
    Background and objectives: The knowledge of depth infiltration in non-melanoma skin cancer (NMSC) using pre-operative ultrasound could enable clinicians to choose the most adequate therapeutic approach, avoiding unnecessary surgeries and expensive imaging methods, delaying diagnosis and treatment. Our single-center retrospective study determined the usefulness of high-frequency ultrasound (HFUS) for depth infiltration assessment in auricular and nasal NMSC and assessed the subsequent change in therapeutic approach.Patients and Methods: In 60 NMSC cases, we assessed the accuracy of HFUS in cartilaginous/bone infiltration detection as well as the correlation of sonographic and histological parameters.Results: In 16.6% of cases, a deep cartilaginous/bone involvement or locoregional disease was identified pre-operatively, resulting in a changed therapeutical scheme of radio-immunological treatment rather than surgery. In two cases, pre-operative HFUS identified local cartilage infiltration, reducing the number of surgical procedures. Forty-eight remaining lesions with no depth infiltration were excised; a correlation of > 99% between the histologic and sonographic tumor depth (p<0.001) was found.Conclusions: Pre-surgical HFUS influences the therapeutic management in NMSC by detecting subclinical involvement of deeper structures, avoiding more extensive diagnostics, reducing costs, and improving healthcare quality. High-frequency ultrasound should be implemented in dermatosurgery before tumor excision for optimized therapy and improved patient counseling.

    Ultrasound Assessment of Skin Tumors Local Recurrence
    (2023) Catalano, Orlando; Crisan, Diana; Gonzalez Diaz, Claudia Patricia; Cavallieri, Fernanda; Varelli, Carlo; Wortsman, Ximena
    Skin cancer may recur at or around the surgical site despite wide excisions. Prompt clinical and sonographic detection of local recurrence is important since subjects with relapsing melanomas or nonmelanoma malignancies can be managed efficaciously, with a relevant impact on morbidity and survival. Ultrasound is being employed with increasing frequency in the assessment of skin tumors, but most of the published articles relate to initial pretherapeutic diagnosis and staging. This review aims to offer an illustrated guide to the sonographic evaluation of locally recurring skin cancer. We introduce the topic, then we provide some sonographic tips for patient follow-up, then we describe the ultrasound findings in case of local recurrence, illustrating the main mimickers, and finally, we mention the role of ultrasound in guiding diagnostic and therapeutic percutaneous procedures.
