| Abstract:Objective：To investigate the appearance of solid papillary carcinoma (SPC) of breast on full-field digital mammography (FFDM) and its clinical pathological features so as to improve the diagnosis of this disease. Methods：The data of 15 cases with breast SPC proved by operation and pathology were analyzed retrospectively. The clinical history, FFDM imaging findings and pathological features were analyzed, and binomial test was performed to evaluate the features of SPC on FFDM. Results：All cases were pathologically diagnosed as SPC, including 1 case combined with high-grade intraductal carcinoma and 1 case with mucinous adenocarcinoma. In 13 patients, FFDM images showed mass lesions: 12 cases had high-density shadows, 9 lesions had clear margins, 4 cases had blurred edges; all 13 cases had microlobulated margins, and 5 lesions had calcification. 1 case showed asymmetrical high density, and 1 case had no obvious mass. The binomial test showed that there were significant differences in microlobulated margins and high-density, but there were no significant differences in other signs. Conclusions：There are some features of SPC on FFDM, such as microlobulated margins and high density. Most lesions have clear edges and are related to pathological features. |
