Abstract
Mucinous carcinoma of the breast has histologically distinct features and constitutes 1-3% of all breast cancers. It produces variable amounts of extracellular epithelial mucin and clinically its prognosis is far better than for other types of invasive carcinoma. On the other hand, coarse calcification is a common mammographic feature of benign tumors. There have been few reported cases of breast cancer containing coarse calcification. We present a unique 40 year-old female case of mucinous carcinoma of the breast accompanied by coarse calcification on mammography, which was mimicking fibroadenoma and an unusual variant of breast cancer. This case illustrates the importance of bearing in mind that mucinous carcinoma may demonstrate coarse calcification.

We present a case of mucinous carcinoma of the breast accompanied by coarse calcification that was evident on mammography, and discuss the mammographic and pathological findings
Coarse calcification is a well-known feature of fibroadenoma with hyalinization, and is rarely seen in breast cancer
Summary
Coarse calcification is a common mammographic feature of benign tumors such as fibroadenoma. Mammographic calcifications associated with malignancy are usually found within ducts and lobules, and do not grow into coarse calcifications. There have been few reported cases of breast cancer containing coarse calcification. We present a case of mucinous carcinoma of the breast accompanied by coarse calcification that was evident on mammography, and discuss the mammographic and pathological findings
