Diagnosis of an extremely rare pleomorphic adenoma of the breast with core needle biopsy: A case report.

ABSTRACT:

Introduction

Pleomorphic adenoma (PA) rarely originates in the mammary gland. This tumor is a benign mixed tumor and is commonly found in the salivary glands, but rarely shows findings similar to those of breast cancer. The tumor is misdiagnosed in 30-50% of the patients, including overdiagnosis of malignancy preoperatively, leading to unnecessary surgery for breast cancer.

Case presentation

The present patient was a 45-year-old woman who exhibited no subjective symptoms. She visited the Takahashi Breast and Gastroenterology Clinic for breast cancer screening. A mass measuring 1.5 cm was palpated in the E region of the left breast. Mammography (MMG) showed a tumor shadow in the left S region. There was a high-density area inside the tumor, suggesting bone or cartilage format
