Use of Immunohistochemistry to Determine Malignancy Type and Help Determine Site of Origin of Metastatic Tumors

Recorded On: 03/25/2020

Registration Closed

Immunohistochemical stains are essential for the correct classification of poorly-differentiated tumors and also play an important role in identifying the most likely site of origin of metastatic tumors. This webinar will discuss commonly used antibodies and algorithms used when diagnosing these difficult tumors. A better understanding of the use of these antibodies allows for an appreciation of the critical role of the immunohistochemistry lab in producing quality slides for these cases. Patterns of staining and choice of antibody clones are essential factors and will be discussed as well.

CEUs: This histology course is worth 1 continuing education credit. Course is available for 365 days from date of purchase.

Medical Director

Dr. Zuehl is a pathologist who specializes in breast pathology and immunohistochemical stains. Since immunohistochemistry involves all aspects of histology, he has a keen interest in all of the histology lab including fixation, processing and histology. He received his medical degree from the University of Wisconsin and his pathology residency was with the U.S. Navy at Walter Reed Hospital in Bethesda, Maryland. Since his father was a pathologist and mother a histotechnician, he blames his childhood exposure to formalin, xylene, and a mistrust of surgeons for his career choice.
