[Ultrasound-guided core needle biopsy for the diagnosis of fibroepithelial breast tumors].

Purpose: to evaluate the concordance rate of ultrasound-guided core needle biopsy followed by excisional biopsy in palpable breast lumps, suggestive of fibroepithelial tumors.

Method: a retrospective study included 70 biopsies with a histological diagnosis of fibroepithelial tumor in 67 out of 531 patients with breast lesions submitted to ultrasound-guided core needle biopsy with a high frequency (7.5 MHz) linear transducer, using an automatic Bard-Magnum gun and a 14-gauge needle.

Diagnosis and management of this unusual Müllerian anomaly are discussed in the context of a literature review.

[Occult metastasis in sentinel lymph node in early-stage breast cancer].

Purpose: sentinel lymph node biopsy in early-stage breast cancer patients has been substituting the total axillary lymph node is presented dissection. The technique of processing the sentinel lymph node and the aim of this study was to investigate the efficacy of occult metastasis identification based on the standard histological and immunohistochemical examination.

Methods: between 2002 and 2005, 266 sentinel lymph nodes were harvested from axillary biopsy of 170 patients with early stage breast cancer.
