Case Presentation: A 42-year-old female presented with a palpable lump in the left breast. Tru-cut biopsy revealed invasive ductal carcinoma ACC form. A breast conserving surgery with sentinel lymph node biopsy were performed. Histopathology revealed ACC with estrogen receptor negative, progesterone receptor negative and HER2-Neu negative type. The multidisciplinary tumor board recommended that neither neoadjuvant nor adjuvant systemic treatment to be offered to this patient. She received adjuvant radiation therapy.
