title: Clinically occult, noncalcified breast cancer: serial radiologic-pathologic correlation in 27 cases.
abstract: A serial radiographic-pathologic correlation based on specimen radiography was performed on 27 consecutive, clinically occult, noncalcified breast cancers to determine the frequency of and correlation between appearances at mammography, pathologic diagnoses, and the features of the histologic margins. Twenty (74%) of the lesions were infiltrating ductal cancers, five (19%) were intraductal cancers, and two (7%) were medullary cancers. Forty-one percent of these malignancies contained microscopic calcifications. Lesions demonstrated at mammography in these 27 cases consisted of a well-defined round mass (n = 1); well-defined lobulated masses (n = 2); indistinct round, oval, or lobulated masses (n = 7); irregular or mixed lesions (n = 7); spiculated masses (n = 9); and architectural distortion (n = 1). Histologic margins of infiltrating and intraductal cancers, created by several types of tumor-fat interfaces and surrounding reactive fibrosis, correlated with these radiographic appearances. Serial specimen radiographic-pathologic correlation can improve our understanding of the appearance of early breast cancer at mammography.
