The aim of this study was to evaluate the sonographic features and to compare the sonographic findings with the pathologic features.
The sonographic and pathological features of all patients were retrospectively reviewed.
All these 9 patients presented with a palpable breast mass first found by the patient before presentation. The median diameters were 3.67 cm. On two-dimensional imaging, 8 masses showed mixed echogenicity with both solid and cystic components, and only 1 mass showed hypoechoic. All the masses had irregular shapes. 1 mass had indistinct margin and 8 masses had microlobulated margins. Calcifications was seen in 1 mass. On color Doppler flow imaging, 8 masses had high vascularity with high resistance index; 5 masses had grade III blood flow signal; 3 masses had grade II blood flow signal. On histopathological examination, 5 masses were adenocarcinoma with squamous metaplasia, and 4 masses were pure SCC. On immunohistochemical staining, estrogen receptors (ER), progesterone receptors (PR) and human epidermal growth factor receptor (HER2) were negative in 5 masses. There were 2 patients with lymph node metastasis.
Most of the sonographic features of MSCC were mixed echogenicity with central cystic components, posterior echo enhancement, abundant vascularity with high resistance.
本研究旨在评估黏液表皮样癌（MSCC）的超声特征，并将其与病理特征进行比较。
回顾性分析所有患者的超声和病理特征。
所有患者均以触及乳腺肿块为首发表现，其中位直径为 3.67cm。二维成像显示，8 个肿块呈混合回声，既有实性成分又有囊性成分，仅 1 个肿块呈低回声。所有肿块均呈不规则形状，1 个肿块边界不清，8 个肿块边界呈细分叶状。1 个肿块内可见钙化。彩色多普勒血流成像显示，8 个肿块血流丰富，阻力指数较高；5 个肿块血流信号为Ⅲ级，3 个肿块血流信号为Ⅱ级。组织病理学检查显示，5 个肿块为伴有鳞状化生的腺癌，4 个肿块为单纯 SCC。免疫组化染色显示，5 个肿块的雌激素受体（ER）、孕激素受体（PR）和人表皮生长因子受体（HER2）均为阴性。有 2 例患者发生淋巴结转移。
MSCC 的大多数超声特征为混合回声，中央有囊性成分，后方回声增强，血流丰富，阻力较高。
