A n 85-year-old woman presented with a mass in the left breast. A3 7mm lobulated mass including enhancement of a cyst of 37mm was detected by sonography. An axillary lymph node had increased to 16 mm. Atypical cells dyed by light green and orange G were identified by fine needle aspiration and cytology. She was diagnosed with left breast cancer(cT2N1M0, Stage II B), histologically suspected to be squamous cell carcinoma. She underwent a left-breast-conserving surgery and axillary lymph node dissection. On pathology, a cyst of 34×30mm was noted. The tumor grew from inside the cyst to the surround- ing tissue and it had a trend for keratinocytes. Lymph node metastases affected 1/11. By immunostaining, the tumor was found to be ER(+), PgR(-), HER2(-), CK5/6(+), p40(+), mammaglobin(-), and GCDFP15(-). There was no component of ductal carcinoma. She received radiotherapy to the left breast and tamoxifen as an adjuvant therapy. Squamous cell carcinoma of the breast is rare. We encountered a case of pure squamous cell carcinoma of the breast in an elderly woman. We report this case with a discussion of the relevant literature.
一名85岁女性因左乳肿物就诊。超声检查发现一个37mm的分叶状肿物，其中包括一个37mm囊肿的强化。一个腋窝淋巴结增大至16mm。通过细针穿刺和细胞学检查发现了被淡绿色和橘黄G染色的非典型细胞。她被诊断为左乳腺癌（cT2N1M0，IIB期），组织学上怀疑为鳞状细胞癌。她接受了保乳手术和腋窝淋巴结清扫术。病理检查发现一个34×30mm的囊肿。肿瘤从囊肿内部生长至周围组织，有角质形成细胞的趋势。淋巴结转移为1/11。通过免疫染色，发现肿瘤为ER(+)、PgR(-)、HER2(-)、CK5/6(+)、p40(+)、乳腺珠蛋白(-)和GCDFP15(-)。没有导管癌成分。她接受了左乳放疗和他莫昔芬辅助治疗。乳腺鳞状细胞癌很罕见。我们遇到了一例老年女性单纯乳腺鳞状细胞癌的病例。我们报告该病例并讨论相关文献。
