A 52-Year-Old Woman Presenting With a Right Breast Mass: A Case Report.

We present the case of a 52-year-old female who presented with a rapidly enlarging right breast mass. An initial breast ultrasound showed a solid mass with cystic components and posterior acoustical enhancement and mammography showed a mass in the same area without calcifications. Biopsy of the lesion revealed spindle cell carcinoma of the breast. To date, the patient has undergone radiation therapy and simple mastectomy and will receive post-operative radiotherapy in the coming months.
