We're trying something fun and new on Dermalogues this episode. It's our very first segment of "Derm Detectives." Think of it as the CDA's version of a true crime podcast. In it, dermatology residents present our two Derm Detectives, Dr Kerri Purdy and Dr Mark Kirchhof, with complex cases they've worked on. Will the Derm Detectives solve the case? Our residents in this episode are Dr Sam Armstrong and Dr Mike MacGillivary, both at Dalhousie University in Halifax.Dr Mark Kirchhof is the Division Head of Dermatology in the Faculty of Medicine at the University of Ottawa and The Ottawa Hospital.If you are a resident with a challenging case you'd like to test on the Derm Detectives, drop us an email at [email protected] (mailto:[email protected]) For more on the work of the CDA, please visit dermatology.ca  (http://dermatology.ca/)And for more great CDA Podcasts, check out JCMS Author Interviews, hosted by Dr Kirk Barber. Dermalogues is produced by the CDA and David McGuffin of Explore Podcast Productions.  Our theme music is by Lee Rosevere
