Intracystic papillary breast carcinoma with areas of infiltration : Report on two cases

Intracystic papillary carcinoma of the breast associated with areas of infiltration is rare in that it constitutes less than 1% of breast cancers. After initial radiological study, these tumors show lesions with little likelihood of malignancy in a high proportion of cases. Two cases of intracystic papillary carcinoma associated with infiltration were diagnosed at the Breast Unit of Hospital Infanta Cristina. In both cases, the reason for consultation arose after palpation of a nodule and the initial radiographic analyses showed lesions with little likelihood of malignancy.
