RIVERA DELGADO, Vanessa  and  LAZO VALLADARES, Ángel. Resultados falsos negativos transoperatorios en los ganglios centinelas de cáncer de mama, asociación con las características histológicas del tumor en el Departamento de Patología del Hospital México.

Breast carcinoma represented de most frequent tumor in Costa Rica during 2013. The axillary dissection in pacients with breast cancer is one of the causes of the most frecuent comorbidity. Studying sentinel ganglion to decide if it is necesary to make an axillary dissection has become very useful in reducing comorbidity in pacients with breast cancer. The surgeon´s and de pathologist´s work experience with this procedure has reduced false positive results in the sentinel ganglion´s biopsies by frezzing method in 4,5%. During the current report the sentinel ganglions by freezing method that had a definite biopsy were studied and we arrived to the conclusion that for our hospital false positives were less than 1,2%. As well in this cases it was determined the histologic type, the histologic grade and the size of the breast cancer. In conclusion it was determined that one of the most frecuent causes associated with false positives is the presence of adipose tissue in the sentinel ganglion.

Keywords : Sentinel node; false negatives; tumors of the breast.
