  2. The A-to-Z Atlas of Head and Neck pathology

An A-to-Z atlas of interesting head and neck pathology, curated and contributed by Dr. Bin Xu . This is a permanent archive from the same effort shared on Twitter during August of 2018, by Dr. Xu. One new letter each day with matching cases.

The scope of head and neck pathology is incredibly diverse, given the wide complexity of organs and specialized structures in this group of sites. This alphabetical trip through some interesting and common pathologies has been curated and shared by Dr. Xu with pathology trainees and veteran practicing pathologists in mind. An excellent effort indeed and I hope you find it as useful and educational as I did. - Chandra Krishnan
