Anatomical Pathology residency: Western University, 2015, followed by Surgical Pathology fellowship (Western University, 2016) with a focus in Gastrointestinal pathology. First job (2016): Western Memorial Hospital, Corner Brook NL in the beautiful Humber valley- an awesome experience, solidifying my anatomical pathology residency knowledge in a general anatomical pathology practice. I invite you to join me on Twitter @redsnapperpath with the global Dermatopathology community- #dermpath #dermtwitter #dermatology #pathtwitter

    I am originally from Ottawa, Ontario but have lived on multiple continents. I obtained my medical degree from the University of Witwatersrand, South Africa. I practiced as a family doctor and emergency physician before returning to academic medicine as a registrar in Anatomical Pathology at Wits University. I returned to Canada in 2014, and completed residency training in General Pathology. I then obtained a fellowship in dermatopathology in Halifax, Nova Scotia, before returning to Saskatoon, where I have been working at Saskatoon City Hospital since August, 2021. My academic interests include dermatopathology, breast pathology, and medical education.

    Dr Karen Naert is a dermatopathologist with Alberta Precision Labs and the University of Calgary in Calgary, Alberta. She completed anatomic pathology residency at the University of Calgary followed by dermatopathology fellowship training at UHN in Toronto.

    I was born and raised in Calgary, Alberta. I obtained my Bachelor of Science with a major in neuroscience from the University of Lethbridge. I then attended medical school in the Caribbean, at the Medical University of the Americas, on the island of Nevis, in the West Indies. I then completed my pathology residency (AP/CP) at the University of Arkansas for Medical Sciences (UAMS), in Little Rock, Arkansas. Next I did a fellowship in dermatopathology also at UAMS, followed by a year of academic practice. Most recently, my family (my husband, 2 children, 2 cats and 1 dog), moved back to Canada to establish our lives here in Saskatoon. I have been working at Saskatoon City Hospital since August 2021.

We would like to present a case based presentation of challenging cutaneous spitzoid lesions from our consultation services in Saskatoon and Calgary.
This course will be open for not only Dermatopathologists, but also all Anatomical Pathologists who sign out skin in their daily practice.

We believe this would be very useful, in particular for those without Dematopathology training and who sign out skin in their practice as this category of melanocytic lesions are ever expanding, becoming increasingly complex and prone to misdiagnosis (under or over calling). As well, and unfortunately (perhaps), to correctly classify these lesions, the ancillary methods may not be available to all laboratories in Canada. These challenges will also be discussed in this workshop.

All participants will receive the digital cases prior to the workshop. We encourage a highly interactive session!


  • Demonstrate the breadth of cutaneous spitzoid lesions including benign, intermediate and malignant examples
  • Share and discuss new immunohistochemical and molecular methods required to evaluate and correctly classify spitzoid lesions
  • Discuss the value of access to Dermatopathologists in diagnosing cutaneous spitzoid lesions
  • Highlight the fiscal challenges for laboratories in utilising comprehensive
  • Dermatopathology consultation methods in correctly classifying cutaneous spitzoid lesions
