BACKGROUND
Squamous cell carcinoma (SCC) of the breast is a rare form of breast cancer, accounting for approximately 0.1% of all breast cancers. It is known for its rapid tumor growth and poor prognosis with no established treatment.
CASE PRESENTATION
A 56-year-old woman was diagnosed with breast SCC with axillary, supraclavicular and internal thoracic lymph node metastases. She received neoadjuvant chemotherapy (NAC) with dose-dense doxorubicin and cyclophosphamide (AC) followed by dose-dense paclitaxel (PTX). This treatment resulted in a pathological complete response (pCR) after breast-conserving surgery. The patient was then treated with radiotherapy. She remained free of recurrence for three years postoperatively.
CONCLUSIONS
We report a rare case of breast SCC treated with preoperative dose-dense chemotherapy, resulting in pCR and allowing breast-conserving surgery.
背景
乳腺鳞状细胞癌（SCC）是一种罕见的乳腺癌形式，约占所有乳腺癌的0.1%。它以肿瘤生长迅速和预后差而闻名，且尚无既定的治疗方法。
病例介绍
一名56岁女性被诊断为乳腺SCC伴腋窝、锁骨上和胸廓内淋巴结转移。她接受了新辅助化疗（NAC），采用剂量密集型阿霉素和环磷酰胺（AC），随后是剂量密集型紫杉醇（PTX）。这种治疗在保乳手术后导致了病理完全缓解（pCR）。患者随后接受了放疗。术后三年她一直无复发。
结论
我们报告了一例罕见的乳腺SCC病例，采用术前剂量密集化疗进行治疗，导致pCR并允许进行保乳手术。
