[Sentinel lymph node biopsy in male breast cancer - a case report].
We report a case of breast cancer in a man who underwent sentinel lymph node biopsy (SLNB). The patient, a 66-year-old man, observed a tumor under his left areola. The elastic hard tumor had a clear border. Ultrasonography revealed a hypoechoic tumor, approximately 18 mm in diameter, in the left subareolar and outer upper region. On fine needle aspiration cytology (FNAC), the tumor was diagnosed as a ductal carcinoma. The patient underwent a mastectomy (Bt) and an axillaryly mph node dissection(Ax)after the SLNB. The SLNB was performed with the blue dye alone. Based on histopathological observations, estrogen receptor (ER)- and progesterone receptor (PgR)-positive invasive micropapillary carcinoma was diagnosed. The human epidermal growth factor receptor 2(HER2) score was 1+, and Ki-67 labeling index was 30%. Lymph node metastasis was not seen in SLNB (0/1) and Ax (0/13). Postoperatively, the patient received oral tamoxifen therapy. There was no evidence of recurrence during the 9-month follow-up. In this case, computed tomographic (CT) lymphography (CTLG) and SLNB were performed successfully, without incident. We recommend SLNB in cases of male breast cancer with clinically negative nodes.
