Another case of matrix-producing metaplastic breast carcinoma. The tumor cells are in close contact with myxoid matrix. There is no spindle cell component.

Hormone receptor status: Like other subtypes of metaplastic carcinomas, matrix-producing breast carcinomas are negative for ER, PR, and AR. They are also negative for Her2.
