Abstract

|
|
Sentinel lymph node biopsy has been developed as the standard of treatment in breast cancer. Status of axillary sentinel lymph node is known to be a significant prognostic factor. Nevertheless, involvement of an intramammary lymph node with metastasis in breast cancer is a rare radiological and clinical presentation, and with extracapsular extravasation even more uncommon. Historically, reported series of patients with intramammary lymph node diagnosed by final histological examination are small in number and clinical significance of metastasis is still unclear. Here, we report a case of conservative breast cancer surgery with 3 intramammary sentinel lymph nodes containing metastasis and extracapsular extravasation. After multidisciplinary consensus, the patient was surgically reapproached with mastectomy. Even though the 3 intramammary sentinel lymph nodes were positive for metastases, pathology examination did not reveal any signs of malignancy in the mastectomy specimen.
