PURPOSE: Absorbable retaining thread (ART) needle localization utilizes a guiding needle with a thread; this technique was invented to reduce patient discomfort and wire migration. We investigated the feasibility of ultrasound (US)-guided ART needle localization for nonpalpable breast lesions. METHODS: ART needle localization was performed for 26 nonpalpable breast lesions in 26 patients who were scheduled to undergo surgical excision the day after localization. Seventeen breast lesions were initially diagnosed as invasive ductal carcinoma, six as ductal carcinomas in situ, and one as fibrocystic change. The other two cases without an initial pathologic diagnosis had suspicious US features, and excision was planned concomitantly with contralateral breast cancer surgery. The primary outcome was the technical success rate of ART needle localization confirmed by US immediately after the procedure, and the secondary outcomes were the percentage of clear margins on pathology and the complication rate of ART needle localization. RESULTS: The technical success rate of ART needle localization was 96.2% (25 of 26 patients), and the ART was located 1 cm away from the mass in one patient (3.8%). The lesions were successfully removed with clear margins in all 26 patients. No significant complications related to ART needle localization were observed. CONCLUSION: ART needle localization can be an alternative to wire needle localization for nonpalpable breast lesions.

Charcoal can be used for preoperative localization of metastatic lymph nodes in the neck. Charcoal remains stable without causing foreign body reactions during as hort period. However, foreign body reactions may develop if charcoal is left in situ for more than 6 months. We reported a case of charcoal granuloma mimicking local recurrence on fluorodeoxyglucose-positron emission tomography/computed tomography and ultrasonography in a 47-year-old woman who had cervical lymph node dissection due to metastatic invasive ductal carcinoma of the breast.

OBJECTIVETo evaluate the reliability and application of GeneSearch(TM) breast lymph node assay (Genesearch), a real-time fluorescence quatitative PCR method, in intraoperative assay of metastasis in sentinel lymph nodes (SLNs) from breast cancer patients.

METHODSTotally 140 SLNs from 80 patients with breast carcinoma were prospectively studied from May 2010 to August 2010. The 80 patients included 78 women and 2 men who ranged in age from 29 to 85 years, and the median age is 49 years. The expression of CK19 and mammaglobulin in all 140 SLNs were detected by Genesearch, and the results were compared with that of histological evaluation of both frozen and paraffin-embedded sections.

RESULTSAmong SLNs, by histological analyses, there were 121 without metastasis, 17 with macrometastasis, 2 with micrometastasis, and none of isolated tumor cell. By Genesearch, there were 119 without metastasis and 21 with metastasis. Genesearch showed sensitivity of 89.4%, positive predictive value of 81.0%, negative predictive value of 98.3% and specificity of 96.7% by comparing to histological analyses. The concordance between Genesearch and histological analysis was 95.7%. The sensitivity of Genesearch was 15/17 for macrometastasis and 2/2 for micrometastasis.

CONCLUSIONSGenesearch detection presents high sensitivity and specificity in evaluating metastasis of sentinel lymph nodes in breast cancer, but strict performance technically is necessary to avoid false positive and false negative results. Inability of further subtyping for the positive cases might be the key limitations for wide application of this method.

Post-transplantation lymphoproliferative disorders (PTLDs) are a heterogeneous group of diseases that represent serious complications following immunosuppressive therapy for solid organ or hematopoietic-cell recipients. In contrast to B-cell PTLD, T-cell PTLD is less frequent and is not usually associated with Epstein Barr Virus infection. Moreover, to our knowledge, isolated T-cell PTLD involving the breast is extremely rare and this condition has never been reported previously in the literature. Herein, we report a rare case of isolated T-cell PTLD of the breast that occurred after a patient had been treated for allogeneic peripheral blood stem cell transplantation due to acute myeloblastic leukemia.

Metastases to intramammary nodes have been shown to be an independent predictor of poor outcome in patients with breast cancer, such as axillary lymph node metastases. The detection and accurate characterization of these nodes preoperatively is thus crucial for the staging and planning of treatment for breast carcinoma, particularly in cases with axillary lymph node negative disease as it upgrades the disease staging. We herein report the first case where we detected an intra-mammary node on specimen MRI after the primary pathological gross specimen evaluation failed to detect the node.
