Objective: To investigate the ultrasonographic characteristics of solid papillary carcinoma (SPC) of the breast. Methods: We retrospectively analyzed the ultrasonographic characteristics of 65 patients with SPC confirmed by pathology in First Affiliated Hospital of Nanjing Medical University from January 2015 to March 2020. Results: Most of SPC showed masses with hypoechoic, uneven echo, finishing edge, oval, parallel orientation, no calcification, no change of posterior echo, Adler II–III, resistance index (RI) ≤0.7, no lymph node metastasis, and no duct expansion in ultrasound. Compared with SPC in situ, SPC with invasion likely showed the following malignant features: masses with larger size, brim burr or angular margin, irregular shape, non-parallel orientation, calcification, and axillary lymph node metastasis. Conclusion: SPC is rare. It has certain ultrasonographic characteristics, but the accuracy of ultrasonic diagnosis is not high. Combined with the age, medical history, and clinical manifestations of the patients, the diagnosis accuracy of SPC in ultrasound can be improved.
