“…25 According to Wortsman et al, sonography is the only imaging technique to define tumor depth without penetration issues, the best imaging modality to characterize the primary tumor in all axes and perform locoregional staging simultaneously. 26,27 Furthermore, the Color Doppler mode allows clinicians to quantitatively and qualitatively analyze the vascular flow within the tumors, which is one of the most sensitive methods for detecting signs of neovascularity in nodular tumoral lesions. [28][29][30] Sonography does not require contrast agents, is not claustrophobic, and can be performed in real-time, avoiding a delay in therapy initiation.…”

Atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) are rare histomorphological variants of a disease spectrum. After ruling out other tumor entities by immunohistochemistry, PDS can be differentiated from AFX by infiltration into the subcutis, while AFX remains confined to the dermis. The therapeutic approach is more aggressive in PDS as it can potentially metastasize. We assessed the usefulness of preoperative sonography in differentiating between the two tumor entities by identifying a potential subcutaneous infiltration. In our patients (n = 13), preoperative sonography identified and differentiated AFX and PDS with 100% accuracy and even changed the initial histological suspicion of AFX to PDS in 3 cases (23%), which was confirmed after tumor resection. Preoperative sonography of these tumors could strengthen the clinical diagnosis, avoid a delay in therapy initiation and improve patient counseling. While for AFX, micrographic‐controlled surgery suffices, for PDS, resection with 2 cm safety margins and lymph node sonography to rule out lymphonodal involvement is necessary. Hence, ultrasonography can improve clinical practice by providing helpful information for dermatosurgeons, which cannot be obtained during clinical examination.

“…In the dermatosurgical setting, we are often confronted with large tumors, especially SCCs situated on the bold scalp, where sonography can help to map the lesions with high precision and rule out or confirm a bone infiltration, as seen in Figure 5. For such cases, there is no need for additional CT or MRI, as sonography is superior for the evaluation of soft-tissue lesions due to its high resolution [31], see Figure 5.

Ultrasound and high-frequency ultrasound assessment of melanoma and non-melanoma skin cancer in the pre-therapeutical setting is becoming increasingly popular in the field of dermatosurgery and dermatooncology, as it can provide clinicians with relevant, ”in vivo“ parameters regarding tumor lateral and depth extension as well as potential locoregional spread, cancelling the need of more extensive imaging methods and avoiding a delay in diagnosis. Furthermore, preoperative sonography and color Doppler can aid in orienting the clinical diagnosis, being able in numerous situations to differentiate between benign and malignant lesions, which require a different therapeutic approach. This preoperative knowledge is of paramount importance for planning an individualized treatment regimen. Using sonography at the time of diagnosis, important surgical complications, such as neurovascular damage, can be avoided by performing a preoperative neurovascular mapping. Furthermore, sonography can help reduce the number of surgical steps by identifying the lesions’ extent prior to surgery, but it can also spare unnecessary surgical interventions in cases of locally advanced lesions, which infiltrate the bone or already present with locoregional metastases, which usually require modern radiooncological therapies in accordance to European guidelines. With this review, we intend to summarize the current indications of sonography in the field of skin cancer surgery, which can help us improve the therapeutic attitude toward our patients and enhance patient counseling. In the era of modern systemic radiooncological therapies, sonography can help better select patients who qualify for surgical procedures or require systemic treatments due to tumoral extension.

Background: Skin cancer is the most common cancer in human beings. Ultrasound is a powerful and non-invasive imaging technique that has expanded its use in dermatology, including in the skin cancer field. The full range of critical anatomical information provided by ultrasound cannot be deduced from a naked eye examination, palpation, or other imaging techniques such as dermoscopy, confocal microscopy, magnetic resonance imaging, or PET-CT (Positron Emission Tomography-Computed Tomography). Methods: This review practically analyzes the main ultrasonographic features of the most common types of skin cancers and the performance of the locoregional staging according to the literature, which is illustrated by state-of-the-art clinical and ultrasonographic correlations. Results: The most common types of skin cancer show recognizable ultrasonographic patterns. Conclusions: Among the current radiological imaging techniques, ultrasound has the highest axial spatial resolution. Compared to other imaging techniques used in dermatology, it shows the great advantage of penetrating the soft tissues thoroughly, which allows us to detect and identify the most common skin types of skin cancer, including both the primary tumor and its locoregional metastases.
