The National Toxicology Program Nonneoplastic Lesion Atlas

932 views

Published on

The National Toxicology Program (NTP)’s Nonneoplastic Lesion Atlas is a valuable, web-based resource with thousands of high-quality, enlargeable images, diagnostic
guidelines, and preferred NTP terminology for numerous nonneoplastic rodent lesions. The atlas will be used by the NTP and its many pathology partners to standardize lesion diagnosis, terminology, and the way lesions are recorded in NTP studies. The goal is to improve the consistency and accuracy of the diagnosis of nonneoplastic lesions between pathologists and laboratories to improve the organization and utility of the NTP’s nonneoplastic lesion database and, ultimately, our understanding of nonneoplastic lesions. The NTP Nonneoplastic Lesion Atlas is a living document that complements the INHAND publications. In fact, one of the aims of the atlas is to align the NTP terminology with that of the INHAND publications as much as possible. The atlas is also a useful training tool for pathology residents and can be used by any organization to improve their own nonneoplastic lesion database. A total of 56 organs organized into 13 organ systems will be included in the completed project. The atlas is free to the public at http://ntp.niehs.nih.gov/nnl.
