Abstract：Objective To investigate the clinicopathological and ultrasonic characteristics of patients with breast encapsulated papillary
carcinoma (EPC). Methods The clinical data of 51 patients with pathological diagnosis of breast EPC were analyzed retrospectively.
The difference between patients with pure EPC (n=21) and patients with EPC accompanied by invasion or ductal carcinoma in situ
(DCIS) (n=30) were compared. Results Most of the cases in pure EPC showed regular morphology and oval shape (81.0%, 17/21),
while most of the cases in EPC accompanied by invasion or DCIS showed irregular morphology (63.3%, 19/30). Most cases in pure
EPC showed edge smoothing (61.9%, 13/21), while those in EPC accompanied by invasion or DCIS showed blurred edges (26.7%,
8/30) and tiny lobulation (30.0%, 9/30). There were statistically significant differences between the two groups in morphology and
edge of tumors (P<0.05). Among 51 cases of breast EPC, 44 cases could be detected with different degrees of blood flow signals,
most of which were grade Ⅲ. Conclusion For pure EPC, benign signs on ultrasound such as mixed cystic and smooth edge, and oval
shape are often observed. If the shape of the lesion is irregular morphology, blurred edges or angulation, it indicates that there is a
high possibility of accompanied by invasion or DCIS, and we should pay attention on the high risk of malignancy.
