	Histobank ID #1406 H&E stained slide showing an area of squamous metaplasia in an otherwise poorly differentiated ductal carcinoma of the breast (NOS). Note the nests of pale pink tumor cells in the center and the more poorly differentiated cells of the rest of the tumor. This type of squamouns metaplasia is very common in murine mammary tumors but not in human. Diagnosis: poorly differentiated breast cancer with squamous metaplasia		Histobank ID #1404 H&E stained slide showing an area of squamous metaplasia in an otherwise poorly differentiated ductal carcinoma of the breast (NOS). Note the nests of pale pink tumor cells in the center and the more poorly differentiated cells of the rest of the tumor. This type of squamouns metaplasia is very common in murine mammary tumors but not in human. Diagnosis: poorly differentiated breast cancer with squamous metaplasia

	Histobank ID #1405 H&E stained slide showing an area of squamous metaplasia in an otherwise poorly differentiated ductal carcinoma of the breast (NOS). Note the nests of pale pink tumor cells in the center in contrast to the more poorly differentiated cells darker staining cells of the rest of the tumor. This type of squamouns metaplasia is very common in murine mammary tumors but not in human. Diagnosis: poorly differentiated breast cancer with squamous metaplasia		Histobank ID #1407 H&E stained slide showing an area of squamous metaplasia in an otherwise poorly differentiated ductal carcinoma of the breast (NOS). Note the nests of pale pink tumor cells in the center. The bright pink cytoplasm is keratin (dyskeratosis). One can find slender strands of cytoplasm running parallel to the rigid membranes of two adjacent cells. This type of squamouns metaplasia is very common in murine mammary tumors but not in human.
