Bottom Line: The development of accessory breast tissue, which is found anywhere along the milk line, is attributed to the failure of milk line remnants to regress during embryogenesis.The second case was a 53-year-old Chinese female with bilateral breast cancer (apocrine carcinoma) accompanied by an accessory breast carcinoma (IDC-NOS) in her right axilla that was also incidentally identified.The patient was surgically treated after three doses of cyclophosphamide epirubicin docetaxel (CET) neoadjuvant chemotherapy, followed by adjuvant chemotherapy of the same regimen.

ABSTRACT
The development of accessory breast tissue, which is found anywhere along the milk line, is attributed to the failure of milk line remnants to regress during embryogenesis. Primary tumors may arise from any ectopic breast tissue. Accessory breast cancer occurring concurrently with primary invasive breast cancer is extremely rare. Two such cases were reported in this article. One was a 43-year-old Chinese female who exhibited bilateral breast cancer (invasive ductal carcinoma, not otherwise specified, IDC-NOS) and an accessory breast carcinoma (IDC-NOS) incidentally identified in her left axilla. The ectopic breast tissue in her right axilla presented with adenosis. The patient was surgically treated, followed by postoperative docetaxel epirubicin (TE) chemotherapy. The second case was a 53-year-old Chinese female with bilateral breast cancer (apocrine carcinoma) accompanied by an accessory breast carcinoma (IDC-NOS) in her right axilla that was also incidentally identified. The patient was surgically treated after three doses of cyclophosphamide epirubicin docetaxel (CET) neoadjuvant chemotherapy, followed by adjuvant chemotherapy of the same regimen.

f4: Case two. Breast mastectomy specimens and the dissection method: right (A) and left (B).

Mentions: Mastectomy specimens with axillary contents were also placed en bloc in formalin for 48 h, and were then dissected. The right mastectomy specimen measured 20.5 cm × 19 cm × 4.5 cm (Figure 4A). A mass measuring 1.8 cm × 1.2 cm × 0.5 cm was identified in the areola of the breast. The cut surface of the tumor revealed firm and gray tissue with irregular boundary. Seventeen lymph nodes ranging from 0.3 cm to 2.5 cm in diameter were found in the right axilla. A 2.1-cm mass was also noted in the axilla. This mass was far from the breast parenchyma and its tissue texture was different from that of the other lymph nodes on the cut surface. The left mastectomy specimen measured 22 cm × 18 cm × 2 cm (Figure 4B). A mass measuring 1.5 cm × 1 cm × 0.7 cm was located on the side of the nipple. The mass was firm, with irregular boundary on the cut surface. Sixteen lymph nodes ranging from 0.3 cm to 1.8 cm in diameter were identified in the left axillary content.
