目的比较超声生物显微镜（UBM）和常规高频超声（HFUS）对鲍文氏病（BD）的影像学表现。方法回顾性纳入28例患者的29个经病理证实的BD病灶，且均为手术后。所有病变均使用 UBM 和 HFUS 进行成像。分析比较 HFUS 和 UBM 的影像学特征。 BD超声诊断结果以病理结果为参考。结果29个(100%)BD病灶在UBM和HFUS上均出现低回声、实性成分和浅表高回声层(即角化)。 BD 病变的典型影像学特征，即浸润深度仅限于表皮，在 UBM 上可见 25 个（86.2%，25/29）个病变，而在 HFUS 上有 15 个（51.7%，15/29）个病变（P = .002）。与 BD 病变表面角化相对应的“波征”在 UBM 上的 17 个 BD 病变 (58.6%, 17/29) 中可见，而在 HFUS 上有 6 个 (20.7%, 6/29) (P=.001)。 UBM和HFUS分别正确诊断了25个（86.2%，25/29）和15个（51.7%，15/29）BD病变（P=0.002）。结论Bowen病在US上具有一些典型的影像学特征。与HFUS相比，UBM可以更好地描绘浅层高回声层的“波征”以及表皮肿瘤与真皮层略高回声之间的清晰边界，从而使BD的诊断更加准确。由于其高分辨率，UBM 有潜力用作 BD 表征的诊断工具。
ObjectivesTo compare the imaging findings of Bowen's disease (BD) between ultrasound biomicroscopy (UBM) and conventional high‐frequency ultrasound (HFUS).MethodsA total of 29 pathologically proven BD lesions in 28 patients were retrospectively enrolled in the study, and all were after surgery. All the lesions were imaged with both UBM and HFUS. The imaging features on HFUS and UBM were analyzed and compared. The diagnostic results of ultrasound for BD were referenced with pathology results.ResultsAll the 29 (100%) BD lesions appeared hypoechogenicity, solid component, and superficial hyperechoic layer (ie, keratinization) on both UBM and HFUS. The typical imaging feature of BD lesions, that was, infiltration depth confined to the epidermis, was visualized in 25 (86.2%, 25/29) lesions on UBM whereas 15 (51.7%, 15/29) on HFUS (P= .002). A “wave sign,” which corresponds to the surface keratinization of BD lesion, was visualized in 17 (58.6%, 17/29) of BD lesions on UBM whereas 6 (20.7%, 6/29) on HFUS (P= .001). UBM and HFUS correctly diagnosed 25 (86.2%, 25/29) and 15 (51.7%, 15/29) BD lesions, respectively (P= .002).ConclusionsBowen's disease has some typical imaging features on US. The “wave sign” of the superficial hyperechoic layer and the clear borderline between the tumor in epidermis and the slightly hyperechoic dermis layer are better depicted by UBM in comparison with HFUS, which leads to a more accurate diagnosis of BD. UBM has potential to be used as a diagnostic tool for characterization of BD on account of its high resolution.
