Immunohistochemical studies are increasingly used to assist the diagnostic evaluation of breast lesions. The activity will emphasize potential pitfalls in interpretation and will discuss both common as well as less recognized (but often more challenging) sources of diagnostic error. You will learn correlative morphologic features to help you interpret confusing or indeterminate IHC results. You will also gain an understanding of the appropriate settings in which these IHC studies may be diagnostically helpful and an appreciation of their uses and limitations in daily practice.
After you complete the activity, you will be presented with a 5-question posttest.
As a result of participating in this activity, you should be able to:
- Interpret commonly used immunohistochemical studies.
- Recognize potential interpretative pitfalls.
- Utilize correlative morphologic features to avoid misdiagnosis.
