Objective To assess the value of ultrasonic elastography in the diagnosis of special type breast cancers. Methods Routine ultrasonograms, color Doppler flow images and elasticity images of 13 patients with special type breast cancer confirmed surgical pathologically were retrospectively analyzed. Results The score of mucinous carcinoma, inflammatory breast cancer (1 patient), lactation breast cancer, invasive micropapillary carcinoma, tubular carcinoma and invasive lobular carcinoma (2 patients) were 4-5. The score of 1 patient of invasive lobular carcinoma was 1 and 1 patient of lactation breast cancer was 3. The characteristics of color Doppler flow imaging of majority patients were varies, while no obvious lesion was observed in Paget's disease. Conclusion Ultrasonic elastography is helpful to the diagnosis of inflammatory breast cancer, lactation breast cancer, invasive micropapillary carcinoma of the breast, papillary carcinoma and tubular carcinoma of the breast. Early diagnosis of Paget's disease still depends on pathology.
