[Patients' information in percutaneous core breast biopsy]. / Le don d'information dans les prélèvements percutanés mammaires: savoir le dire, savoir le faire.

Information takes a large part of patient's perceptions of the procedure. If the information is adapted, patients tolerate the procedure well. We point out indications and explain the different types of procedure. For infraclinical masses, sonographically guided automated core needle biopsy removes samples. Sonographically guided vacuum-assisted large-core biopsy is only used for diagnosis generally on second purpose for masses. Stereotaxic vacuum-assisted large-core biopsy is used for microcalcifications (needle 8 or 11 gauge). Haematoma and bleeding are rare (< 4%), but care is necessary to avoid complications. Information is executed before the procedure and a booklet is giving to the women. This information has to be adapted because lot of informations could increase patient's anxiety if they don't want more informations and "not enough information" could also increase anxiety if they want more informations. The practitioner, by hearing, his formation and his experience, is able to adapt informations.

Mammography of ductal carcinoma in situ of the breast: review of 909 cases with radiographic-pathologic correlations.

We retrospectively analysed mammographies of 909 ductal carcinoma in situ (DCIS) (1980-1999) and compared our results to those of literature. Microcalcifications were present in 75% of the cases, and soft-tissue abnormalities in 27% cases with association with calcifications in 14% of cases. Palpable masses were found in 12% of the cases and nipple discharge was present in 12% of the cases. The radiographic-pathologic correlation allowed to suspect the DCIS "aggressiveness" on radiologic signs. Granular, linear, branching and/or galactophoric topography of the microcalcifications were correlated with necrosis, grade 3, comedocarcinoma type. A number of microcalcifications higher than 20 was correlated with necrosis and grade 3. Mammographic size was correlated to histologic size. Masses were correlated with grade 1. A diagnosis strategy can be proposed with a multidisciplinar approach.

[Diagnostic approach to breast papillary lesions]. / Approche diagnostique dans les lesions papillaires du sein.

Breast papillary lesions are difficult to interpret and include a large variety of benign, atypical and malignant lesions. We report the case of a 41-Year-old woman presenting with an intracystic papillary carcinoma, in order to illustrate our pragmatic diagnostic approach, which includes the use of a decision tree, useful for differentiating the different types of breast papillary lesions.
