چکیده

BACKGROUND AND OBJECTIVE With advances in mammographic equipment and techniques, more and more nonpalpable breast lesions have been detected. This study was to investigate the application of methylene blue dye for localized biopsy to diagnose nonpalpable breast lesions. METHODS In total 138 patients with suspicious malignant, nonpalpable breast lesions between August 2002 and October 2006 were enrolled. A small dose of methylene blue was injected into the lesion under mammographic guidance. The dyed tissues were excised completely via an optimal incision, and radiographys was obtained to confirm the removal of the nonpalpable lesion. The specimen weight and incision length were measured. RESULTS Suspicious lesions in all 138 patients were accurately excised. Eighty-four (60.9%) patients were confirmed as breast cancer, and 54 (39.1) were diagnosed with benign lesions. The mean length of the incision was 4.6 cm (range 3.2-5.3 cm), and the mean weight of the resected specimen was 42 g (range18-86 g). All patients achieved stage I healing. CONCLUSIONS Excisional biopsy is recommended for nonpalpable breast lesions which are highly suggestive of malignancy by imaging examination. Methylene blue guided localization and excisional biopsy is a safe, relatively simply procedure with high diagnostic accuracy.

Marking non-palpable breast masses with injected methylene blue dye, an easy, safe and low cost method for developing countries and resource-limited areas.

INTRODUCTION The widespread use of improved mammographic techniques has led to increased detection of nonpalpable breast masses. Preoperative localization is important for reducing false negative results and decreasing the size of tissue resection needed and the resulting breast deformity. We used ultrasound guided methylen blue injection in the mass for localization of breast masses that were ...

Retrospective analysis of sentinel node localization in multifocal, multicentric, palpable, or nonpalpable breast cancer.

UNLABELLED Multicentric or multifocal breast cancer is considered as one of the limitations for sentinel lymph node (SLN) localization. We did a retrospective analysis to evaluate the success rate, sensitivity, accuracy, and negative predictive values of SLN localization in multicentric or multifocal breast lesions. METHODS Fifty-nine patients with multifocal or multicentric breast lesions pr...

Methylene Blue Dye-Induced Skin Necrosis in Immediate Breast Reconstruction: Evaluation and Management

BACKGROUND For early breast cancer patients, skin-sparing mastectomy or nipple-sparing mastectomy with sentinel lymph node biopsy has become the mainstream treatment for immediate breast reconstruction in possible cases. However, a few cases of skin necrosis caused by methylene blue dye (MBD) used for sentinel lymph node localization have been reported. METHODS Immediate breast reconstruction...

Skin and fat necrosis of the breast following methylene blue dye injection for sentinel node biopsy in a patient with breast cancer

Sentinel lymph node biopsy (SLNB) is a simple technique that uses subdermal or peri-tumoral injection of vital blue dye and/or radioactive isotope to identify the first lymph node(s) draining the primary tumor. It has been shown to accurately predict axillary node status in patients with clinically node negative breast cancer. The SLNB is emerging as a new standard of care in patients with earl...
