PurposeTo analyze the sonographic and the histological features of special types of breast malignant tumors in order to explore preoperative ultrasound diagnosis. Materials and Methods Seven cases of special types of breast malignant tumors confirmed by pathology were retrospectively investigated by ultrasound. The sonographic and histological features of the lesions were reviewed. The ultrasonogram manifestations of the breast anatomy and the lesions were observed and recorded.Results Among 7 cases, there were 2 cases of papillary carcinoma, 3 cases of mucinous carcinoma, and 2 cases of lymphoma. Microscopically, the papillary carcinoma had clear boundaries with infringing mesenchyme, and the tissues were papillary and dense. The mucinous carcinoma had cancer cells floated in mucus lake. The primary breast lymphoma was diffused large B-cell type with focal lesion. For sonography type of breast, there were 3 cases of fatty types, 1 case of fibroglandular-1 and 3 cases of fibroglandular-2. The papillary carcinoma was hypoechoic in 2 cases, one of them was expansive growth with large size. Two cases of mucinous carcinoma were hypoechoic without accompanying sound attenuation in 1 case and with accompanying acoustic shadow due to calcification in the other case. Lymphoma was apparent anechoic and cystoid.Conclusion Special types of breast malignancies have different sonographic features and histological features from the common invasive ductal carcinoma. It has high clinical significance to enhance the understanding of rare malignant breast tumors.
