Objective To observe the ultrasonographic and pathological features of metaplastic carcinoma with squamous cell component (MCSC) of the breast. Methods The ultrasonographic and pathological features of 7 patients with breast MCSC confirmed pathologically were retrospectively analyzed. Results Seven cases were single lesion and the maximal diameters of the lesions were 2.6—5.1 cm. On two-dimensional imaging, 6 lesions with cystic and solid were complex echogenic, only 1 lesion was hypoechoic. All the lesions had irregular shape (lobulated)and indistinct margin. On CDFI imaging, most of lesions had rich blood flow signals with high resistance (resistance index 0.75—0.91)， 4 lesions were grade Ⅲ, 2 lesions were grade Ⅱ and 1 lesion was grade Ⅰ blood flow signals. On gross histopathological examination, 6 masses had cystic cavity, only 1 mass was pure solid. On microscopic histopathological examination, 5 masses were adenosquamous carcinoma, only 2 masses were pure squamous cell carcinoma. Estrogen receptors, progesterone receptors and human epidermal growth factor receptor were negative in 4 masses (triple-negative breast cancer). Conclusion MCSC have some distinguished ultrasonic characteristics of larger volume, cystic-solid mixed echo, posterior echo enhancement, abundant vascularity with high resistance.
