Abstract
A 53-year-old man presented at our hospital with a 3.0-cm elastic hard tumor of the left breast. Mammography revealed a round, indistinct tumor shadow and ultrasonography showed a 30.6×12-mm low echoic lesion in the CD region of the left breast.
Histological examination of a core needle biopsy specimen revealed massive necrosis and suspected invasive ductal carcinoma that was later confirmed by immunohistochemical assessment.
The patient was treated by left mastectomy with dissection of the left axillary lymph nodes. Postoperative histological assessment of the resected material revealed massive infarction in the center of the tumor. A few invasive ductal carcinoma cells were viable around the area of infracted necrosis. The nuclear grade was 1 and lymph node metastasis was absent. Estrogen and progesterone receptors were positive, and the HER-2 score was 0. The patient was discharged on postoperative day 10 and has since shown no signs of recurrence.
