The recent development of high-frequency ultrasound, associated with the improved sensitivity in color Doppler, enabled the identification of various skin structures and layers. In basal cell carcinoma, the 22 MHz frequency ultrasound permits the delimitation of tumor margins, while color Doppler, determines its vascularization. We present two cases in which the association of both exams allowed an in vivo analysis of the tumor's morphology, size, thickness and vascularization, thus contributing to a better pre-operative evaluation.
高频超声的最新发展，加之彩色多普勒灵敏度的提高，使得识别各种皮肤结构和层次成为可能。在基底细胞癌中，22兆赫频率的超声能够界定肿瘤边缘，而彩色多普勒则可确定其血管分布情况。我们展示了两个病例，其中两种检查相结合能够对肿瘤的形态、大小、厚度及血管分布进行活体分析，从而有助于更好地进行术前评估。
