title: Metaplastic carcinoma of the breast: clinical, mammographic, and sonographic findings with histopathologic correlation.
abstract: OBJECTIVE
  The purpose of this study was to investigate the mammographic and sonographic findings of metaplastic carcinoma of the breast and to correlate the radiologic features with clinical and histopathologic findings.
  
  
  CONCLUSIONS
  Metaplastic carcinoma of the breast often manifests as a rapidly growing, palpable mass that has high density on mammography and may be microlobulated on sonography. Complex echogenicity with solid and cystic components may be seen sonographically and is related to necrosis and cystic degeneration found histopathologically. Although it is a rare breast malignancy and these features are not unique, metaplastic carcinoma should be included in the differential diagnosis for breast masses with these imaging features.
