Abstract

Dermatopathology education meaningfully relies on consultation of books, which are expensive, quickly outdated and have limited possibilities. In recent years, virtual microscopy, a method that enables examination of digitized microscopy samples, has earn interest because of its possibilities in terms of interaction, availability, usability, low costs and adaptation to multiple clinic scenarios. This work introduces a customized low-cost system for consultation of dermatopathology samples. First, physical slides are digitized using an optical microscope coupled to a digital camera controlled by a custom-motorized scanner. Then, digitized images are automatically stitched to assembly the Whole Slide Image (WSI). A web application, developed using open source tools, gives access to such WSI and allows users to interact with the content by panning and zooming. The application also allows to hand-free annotate specific regions. A set of 100 dermatopathology slides, provided by the Pathology Department of the Universidad Nacional de Colombia, representing basic lesions and inflammatory skin diseases (based on Ackerman patterns) were digitized. Each WSI contains diagnosis and annotations of relevant regions. The platform is currently being used by trainees who highlight the benefits of this kind of tools that complement their training and help to improve their diagnostic skills.
