Lookingbill and Marks’ Principles of Dermatology is a textbook by Elsevier that is considered a great resource for introductory material in the field of dermatology. The text covers a full range of skin diseases and can be a great resource to quickly reference. The textbook has now also been converted to an app format by Usatine Media for portable use.

User Interface

The textbook opens with a table of contents that is separated by larger subheadings to categorize the chapters. The main page also has a menu bar along the bottom of the screen that allows users to search the textbook, look at bookmarks and read their previous notes from the text.

The app also allows the user to take notes that are attached to each chapter. Unfortunately, the notes cannot be added to specific subsections of the app as would be possible with a physical textbook. The app also has the option to bookmark sections that can be retrieved from the bookmark tab on the main screen.

The app also includes a self- assessment section that has 17 cases. Each case presents an image of a disease and asks for the differential diagnosis, work-up and treatment.
