F131 - Dermatopathology Case Challenge: Recognizing Mimics and Masqueraders

Monday, March 4; 3:30 PM - 5:30 PM

Learning Objectives

Following this course, the attendee should be able to:

  • Identify diagnostic entities that present as mimics in dermatopathology.
  • Recognize clinical and histopathologic features that can help avoid diagnostic pitfalls when faced with a dermatopathologic mimic.
  • Utilize ancillary tests when appropriate to enhance diagnostic accuracy in challenging dermatopathologic cases.


Diagnostic mimics in dermatopathology pose a potential pitfall in the provision of accurate diagnostic interpretation of patient biopsies. This session intends to provide dermatopathologists, dermatologists, and those in training with enhanced awareness of both common and novel mimics that may be encountered in dermatopathologic practice. An interactive case-based format will be utilized and speakers will describe glass slide masqueraders that they have faced, ancillary tools employed, and the lessons learned in reaching the correct interpretation. Both inflammatory and neoplastic dermatopathologic cases will be presented.
