摘要

目的：

探讨超声在诊断乳腺化生性癌（metaplastic carcinoma of the breast，MBC）中的价值。

方法：

回顾并分析2015年1月2019年12月于南京医科大学第一附属医院经手术后病理学检查证实的26例MBC患者的二维超声及彩色多普勒超声特征。

结果：

MBC患者多为绝经后妇女，肿块较大，超声特征多表现为低回声，内部回声不均匀，边缘光整，形态不规则，平行于皮肤，无钙化或微小钙化，后方回声无改变或增强，腋窝淋巴结发生转移，Adler分级Ⅱ~Ⅲ级多见，阻力指数（resistance index，RI）＞0.7，部分征象与乳腺浸润性癌相同。与间叶化生癌相比，鳞状细胞癌多表现为直径较大、呈囊实性回声、腋窝淋巴结无转移。

结论：

MBC较罕见，病理学亚型多样，术前超声确诊较困难，但因其多具有恶性肿瘤的常见声像图特征，一般可以判断为恶性肿块。

Abstract

Objective:

To investigate the value of ultrasound in the diagnosis of metaplastic carcinoma of the breast (MBC).

Methods:

The features of two-dimensional ultrasound and color Doppler ultrasound of 26 patients with MBC confirmed by pathology in the First Affiliated Hospital of Nanjing Medical University from January 2015 to December 2019 were retrospectively analyzed.

Results:

The majority of MBC occurred in the postmenopausal women. The masses of MBC mostly showed hypoechoic

heterogenous echo

complete edge

irregular shape

parallel to the skin

without calcification or with microcalcification

no change or attenuat

ion of posterior echo

lymph node metastasis

Adler Ⅱ-Ⅲ and resistance index (RI)＞0.7 in ultrasound. Some of the signs were the same as invasive breast carcinoma. Compared with MBC with mesenchymal differentiation

squamous cell carcinoma showed larger diameter

complex cystic and solid echo and no axillary lymph node metastasis.

Conclusion:

MBC is rare and contains multiple pathological subtypes

so it is difficult to be diagnosed as MBC by preoperative ultrasound. But because most of them have common ultrasonographic features of malignant tumor

it can be diagnosed as malignant tumor generally.
