Neuroblastoma Tumor Atlas

The Informatics & Communication Committee, on behalf of the SPP, would like to introduce the first of several digital pediatric atlases - the Atlas of Neuroblastic Tumors. The atlas represents an annotated walkthrough neuroblastic tumors using examples from the central review files is now available to visitors to the SPP website.

Members are encouraged to visit the atlas to review classic images and descriptions of different neuroblastic tumors. We hope this provides a valuable reference and teaching tool for residents and fellow trainees. 

The Informatics & Communications Committee would like to thank the members of the International Neuroblastoma Pathology Committee for contributing this atlas.
