Objective:

To investigate the ultrasonographic features of solid papillary carcinoma (SPC) of the breast and differential diagnosis from intraductal papilloma of the breast (BIDP).

Methods:

The ultrasonographic features and clinical manifestations of 65 patients with SPC and 77 patients with BIDP confirmed by pathology in the First Affiliated Hospital of NJMU from January 20

15 to March 2020 were retrospectively reviewed. Differential diagnosis was performed.

Results:

There were significant differences in age

lesion type

distance from the nipple

size

uniformity of the echo

axillary lymph node metastasis

Breast Imaging Report and Data System (BI-RADS) grades between SPC and BIDP（

P

＜0.05）. Compared with BIDP

the majority of SPC patients showed the older age

single solid mass

higher palpation rate

longer distance from the nipple

larger size

nonuniformity of the echo

axillary lymph node metastasis and higher probability of BI-RADS 4. There were no significant differences in echo

edge

shape

orientation

calcification

posterior echo

Adler

resistance index (RI) or duct expansion (

P

＞0.05).

Conclusion:

SPC has certain ultrasonographic features. Combing with the age

medical history and clinical manifestations of the patient are helpful in differential diagnosis SPC from BIDP.
