It highlights the significance of recognizing biphasic cellular elements and the overall architecture of the tumor in combination with immunohistochemistry during the diagnosis of AMEs. Topics include microscopic pathology and immunohistochemistry; differential diagnosis; and biologic behavior and treatment.
