The internet is increasingly being used to distribute knowledge in medicine in novel and unconventional ways. In this article, we give a brief introduction into the website www.derm101.com, which was founded by A. B. Ackerman for the purpose of teaching dermatology and dermatopathology. A clinical atlas, online books such as the 3rd edition of his volume "Histologic diagnosis of inflammatory skin diseases", works on clues and differential diagnoses in dermatopathology, a resource on therapeutic strategies in dermatology, a video lecture library on controversial issues in dermatology, the quarterly online journal Dermatopathology: Practical and Conceptual and much more can be found on derm101.com. The site is enriched with new contents biweekly and offers several interactive teaching devices. Currently, www.derm101.com is the most comprehensive online library of dermatology resources.
