Abstract

Squamous cell carcinoma is a rare histological type of breast cancer classified as metaplastic carcinoma. Metaplastic carcinoma involves differentiation of the breast glandular duct cells into mesenchymal tissues. While the chemotherapy regimen for metaplastic carcinoma is often similar to that for invasive ductal carcinoma, recurrence is associated with a poor prognosis due to the inadequate therapeutic efficacy of the regimen. We herein present the case of a 42-year-old female patient who underwent mastectomy of the right breast and right axillary node lymphadenectomy for T4N3aM0 breast cancer stage. The cancer was histopathologically diagnosed as squamous cell carcinoma of the breast. Adjuvant cyclophosphamide-epirubicin-fluorouracil (CEF) postoperative chemotherapy was administered, and lymphadenectomy of right-sided parasternal lymphatic metastases with pleural drainage was subsequently performed. Radiotherapy was administered to the thoracic wall and supraclavicular lymph nodes at 60 Gy. Positron emission tomography (PET)-computed tomography (CT) examination 3 months after the radiotherapy identified accumulation of fluorodeoxyglucose (FDG) in a supraclavicular lymph node and the thoracic wall; hence, a chemotherapeutic r...Continue Reading
