[Non-palpable lesions of the breast. Preoperative location techniques with vegetable charcoal].

Purpose: Mammography and US increase the rate of early breast cancer diagnoses. The difficult intraoperative location of nonpalpable lesions has led to the development of various techniques suitable to this purpose. We investigated the effectiveness of free-hand vegetable charcoal lesion marking during both mammography and US and compared this technique with other more commonly used methods.

[Non-palpable lesions of the breast. Retrospective analysis of mammographic and ultrasonographic indications for surgery].

Introduction: The differential diagnosis of malignancy in small foci of microcalcifications or in extremely small nodes can be difficult. We carried out a retrospective analysis of integrated mammographic and US results, correlated with histologic data, to assess the limitations of each method and to optimize and benign/malignant ratio.

Materials And Methods: Our series consisted of 485 nonpalpable breast lesions submitted to histologic examination after vegetable charcoal marking.
