Rereleased Activity
This activity was originally released as Use of Immunohistochemistry in the Diagnosis of Breast Lesions (SAM eligible) and was available between June 30, 2011 and June 30, 2014. The content was reviewed in March, 2014 and an updated version of the activity, with the same title, was available between July 1, 2014 and June 30, 2017. The content was reviewed in January 2017. If you completed previous versions, you are NOT eligible to claim CME/SAM credit for completing this updated version.

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 immunohistochemical results. You will also gain an understanding of the appropriate settings in which these immunohistochemical 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 post-test.

After completing this SAM eligible activity and post-test, you should be able to:

  1. Interpret commonly used immunohistochemical studies.
  2. Recognize potential interpretative pitfalls.
  3. Utilize correlative morphologic features to avoid misdiagnosis.
