Description	skin anaplastic carcinoma
Age at Necropsy	688 days
Notes	This is a skin cancer, possibly from the mammary gland from a 688 day old female SWR/J mouse. There are nests of locally invasive epithelial cells that are poorly defined with a very high mitotic index. There are extensive areas of necrosis. This is an anaplastic carcinoma. Immunohistochemical analysis is needed to define the cell type of origin.
