METHODS: We presented and displayed a case of feminine patient of 57 years old, that consults to present a display movable tumefaction, non painful, without any inflammatory signs, nor secretion in the left breast. The mammography describes a nodule in left external superior quadrant with characteristics of benign injury.

RESULTS: Oncology partial mastectomy is been made, with untimely biopsy that reported a suitable margins. Next sentinel ganglion dissection was made sentry and axillaries resection of breast supernumerary ipsilateral.
