Metaplastic carcinoma arising in fibroadenoma of breast

Metaplastic carcinoma accounts for less than %1 of all malignant breast lesions. It has a more aggressive behaviour and worse prognosis than other breast carcinomas. Clinically metaplastic carcinomas are more common in women more than 50 years old and usually present as palpable masses. The purpose of this study was to investigate the mammographic, sonographic and magnetic resonance imaging findings of metaplastic carcinoma of the breast and to correlate the radiologic features with clinical and histopathologic findings. We present the clinical and radiological findings of 35 year old woman whose histopathologic diagnosis is metaplastic carcinoma.
