초록
Metaplastic breast carcinoma is uncommon, constitutes ≤5% of all breast cancers, and is classified into various subtypes with varying incidences. Of these subtypes, spindle cell carcinoma represents approximately 0.3% of all invasive breast carcinomas in women. The spindle cell carcinoma subtype of metaplastic breast carcinoma is typically triple negative and has distinct clinical, radiological, and pathological characteristics. To date, there is no effective treatment for this malignancy. Herein, we report a case of spindle cell carcinoma of the breast in a 71 year-old man who presented with a palpable mass in his left breast. Breast ultrasonography revealed a 1.1×2.6 cm hypoechoic well-demarcated ovoid mass. The patient underwent excisional biopsy. Pathological findings indicated a diagnosis of spindle cell carcinoma of the breast, and the patient underwent a modified radical mastectomy. The final pathological report indicated a 6.5×3.0 cm malignant spindle cell tumor.
