Morton introduced cutaneous lymphoscintigraphy in melanoma. His results permitted to reproduce sentinel lymph nodes(SLN) in other areas. Krag and Weaver implemented portable gamma radiation detectors in breast cancer. The aim of this article is to describe the first expertise in our hospital using nuclear medicine in breast cancer and the methodological aspects of SLN and reviewing the international literature. Case Report: Female 54 years, no family history of breast cancer. Medical exam detected a mass of 3x2 cm in the upper outer quadrant of the left breast, there is no axillary mass. The Ultrasound: BIRADS IV A. Mammography: BI-RADS V Preoperative Classification: T2N0M0 Tru Cut Biopsy: Invasive carcinoma no type determined. Triple negative. Extension studies were negative. The lymphoscintigraphy done according to international protocol. Methylene blue was used in conjunction with the radiotracer; a periareolar sub dermal injection was given in the operating room. The Surgery performed on the day marked. After localized the scintigraphic hot spots in vivo with the gamma probe Nuclear Lab DGC II. The intraoperative frozen section analysis used with Haematoxylin and Eosin staining. Two SLN reported as metastases Negative. The axillary dissection was deferred. There were no complications. Post-surgical pathologic report showed invasive carcinoma no type determined size 35 x 30 x 28 mm, unifocal. In situ ductal carcinoma and in situ lobular carcinoma unidentified and lympho-vascular unidentified invasion. There is no tumoral extension to the skin. All margins were reported negative.pT2pN0. Conclusion: Each time that a new therapeutic tool is within reach of the oncologic patients, principally when his effectiveness have been demonstrated to long time. It to make true in low income country increase the challenge for her implementation. However, the multidisciplinary effort of the human resources and the help of the technology development of our institutions permeated to jump the hard barrier that this entails, achieving a great achievement to the patients with breast cancer in our country. This first effort is not distant from the reported in the international literature.
