[Intramammary sentinel lymph node preoperative identification with SPECT/CT in a patient with breast cancer. Clinical meaning and relevance].

We present the case of a patient with breast cancer who underwent selective sentinel lymph node biopsy. An intramammary sentinel lymph node was identified with SPECT/CT in the preoperative lymphoscintigraphy. We describe our diagnostic and therapeutic procedure regarding this finding and the literature review to evaluate the clinical significance of their identification and metastases, especially in regards to more appropriate axillary management. Further studies with more statistical significance are necessary to elucidate the most suitable attitude when an intramammary sentinel lymph node is identified with the lymphoscintigraphy.
