Intracystic carcinomas of the breast are rare entities that constitute 0.3% to 2.0% of all breast carcinomas, and the solid portion may be quite large at the time of diagnosis.3 We attempted to classify the types of sonographic findings of symptomatic cystic lesions of the breast and correlated these findings with the pathologic results.
