It accompanies the physician’s examination, dermoscopy, and biopsy; facilitates real-time assessment of locoregional staging and planning of surgical excision; and provides postoperative inspection of treatment results. The aim of this review article is to discuss HFUS application in common cutaneous malignant tumours while depicting the use of both the grayscale and colour Doppler methods. Key words: skin ultrasound, high-frequency ultrasonography, skin cancer, melanoma, non-melanoma skin cancer, basal cell carcinoma.  \nIntroduction  \nCutaneous malignancies are the most common cancers worldwide [1], therefore their early detection determines increase of morbidity and survival. Since the introduction of ultrasound in 1979 to measure cutaneous thickness [2], skin imaging has kept progressing, resulting in the invention of high-frequency ultrasonography (HFUS) . This non-invasive method precisely depicts lesion characteristics, therefore increases diagnostic accuracy [3], reduces the need for biopsy [4] or supports excision planning.  \nAlthough the conventional ultrasound scanner may assist dermatological diagnosis, HFUS assessment is more accurate as wave resolution and penetration are frequency-dependent – with higher frequency wavelength diminishes, which results in lower ultrasound penetration and better resolution imaging of the skin and subcutaneous tissues [5] .  \nAccording to the DERMUS Group guidelines [6], HFUS needs minimum 15 MHz frequency to differentiate between skin layers [7](preferably 15–22 MHz [8], the lowest frequencies designated for deeper lesions) . HFUS accompanied by colour Doppler imaging and spectral curve analysis evaluates tumour vascularities [6] . Colour Doppler ultrasound differentiates benign from malignant lesions by depicting vessel size, intra- and peritumoral  \ncirculation [9] . It also evaluates inflammation – high disease activity areas [10] show increased blood flow. Threedimensional reconstruction based on large-scale serial tissue sections [11] may be performed.  \nDigital HFUS images should be stored for long-term follow-up combined with clinical observations and prospective histological outcomes [12] .  \nMelanoma  \nMelanoma is a skin cancer with the lowest survival [12] and a rapidly rising incidence rate [13] . HFUS depicts melanoma as hypoechoic, inhomogeneous [14], oblong or oval, well-bordered by hyperechoic epidermis. In ulcerated malignancies the epidermis may be non-continuous or irregular [15] .  \nIn colour Doppler examination melanoma – as anangiogenic tumour – is hypervascular. The flow signal is easier to detect in lesions thicker than 2 mm. Vascularization corresponds with lymph node involvement and survival rate.  \nPreoperative HFUS may determine excision margin as HFUS-measured cancer’s thickness resembles histopathologic results [16–22] especially in superficial melanomas, while evaluation of nodular and vertically spreading tumours is less reliable [23] .
