Metaplastic Carcinoma of the Breast with Chondroid Calcification: A Case Report

Metaplastic carcinoma is a rare form of breast carcinoma in which a variety of metaplastic changes occur. These commonly involve squamous or spindle cells, but pure chondroid metaplasia is relatively uncommon. We report a case of metaplastic carcinoma of the breast which mainly involved chondroid metaplasia and in which chondroid calcifications were seen on mammograms.
