Course Description: This course, the second in the dermatological specimens series, addresses the most common concerns of working with dermatology specimens and provides tips to create high quality slides for the dermatopathologist. Explored topics include optimal processing, sectioning, and recut protocols for skin biopsies, shaves, and excisions. The histomorphology of skin is reviewed and commonly used H&E and special stains are discussed. Possible sources of problems are also investigated and solutions are applied to prevent artifacts on skin sample slides.
