Great find
Format: Paperback
I love this card deck. It has great picture quality of each dx with different areas of the body it can appear on. It has treatment plan for each. Lists different topical steroids and strength. I just wish the paper themselves was thicker.

Great resource!
Format: Paperback
This dermatology resource is great. Created by some of the authors that wrote very good dermatology books. This deck is very colorful and has a lot of explanations. It shows different stages of the various skin conditions. It also gives detailed things to look for and treatment recommendations on the back of each card. Only negative is that the pages are a bit thin. Overall great resource!
