Basal cell carcinoma (BCC) is a malignant skin cancer which commonly exhibits aberrant blood flow because of angiogenesis. Its invasiveness and lack of metastatic potential may be explained by the typical pattern of vascularization seen in BCCs, where blood vessels are absent in the tumor islands and prominent in the tumor's periphery. From clinical point of view, high-frequency ultrasound (HFUS) is a useful tool for the evaluation of the lateral and depth extension of these tumors; furthermore, by employing color Doppler, important data regarding the vascularization degree of BCCs is provided. Knowingly, the sonographic vascular pattern of cutaneous tumors can aid in improving diagnosis and treatment by differentiating between benign and malignant lesions, between various types of cutaneous malignancies and also between various types of BCC (e.g., low risk versus high risk). Our aim was to perform a review integrating all currently known vascular properties of BCC as a tumor entity.
