Abstract

Two histologic types of mammary cancer were encountered in an aged captive California sea lion (Zalophus californianus). A cancer with myoepithelial cell proliferation, which had metastasized to distant viscera, was located in the left cranial mammary region. Another cancer without myoepithelial cell proliferation was located in the right posterior mammary region, formed secondary nodules, and had metastasized to a regional lymph node. The presence of two different neoplasms in this sea lion is unusual.
