Sarcomatoid Carcinoma of the Breast: A Case Report

Sarcomatoid carcinoma or spindle cell carcinoma is an uncommon and aggressive form of breast cancer. It is characterized by an atypical combination of epithelial and mesenchymal components exhibiting sarcomatoid features. However, due to its rarity, there is limited documentation. Herein, we present the case of a 52-year-old lady who had previously undergone simple mastectomy with axillary nodal clearance for spindle cell neoplasm, which had recurred within a month after primary surgery. The patient subsequently underwent a left-sided wide excision of the recurrent lesion followed by a parascapular flap reconstruction. Adjuvant chemotherapy consisting of ifosfamide and adriamycin was administered, followed by locoregional radiation therapy. This case report is valuable in providing insights into the management of such uncommon and challenging cases, given the high frequency of recurrence and the difficulties associated with understanding the clinical and morphological features of this disease.
