About the American Registry of Pathology Press

The American Registry of Pathology (ARP) is dedicated to its mission to advance, educate, and connect the field of pathology by providing the best educational content and expertise. To help fulfill this mission, ARP Press publishes atlases of tumor and non-tumor pathology, also known as the AFIP Fascicles.

History of the AFIP/ARP Fascicles

The Atlas of Tumor Pathology has a long and distinguished history. It was first conceived at a cancer research meeting held in St. Louis in September 1947, as an attempt to standardize the nomenclature of neoplastic diseases. The first series was sponsored by the National Academy of Sciences-National Research Council. Many of the illustrations were provided by the Armed Forces Institute of Pathology (AFIP), which was also responsible for the final printing. ARP purchased the Fascicles from the Government Printing Office and sold them virtually at cost.

They quickly became among the most influential publications on tumor pathology, primarily because of their high quality, but also because their low cost made them easily accessible to pathologists and other students of oncology.

Upon completion of the first series, the National Academy of Sciences-National Research Council handed further pursuit of the project over to the newly created Universities Associated for Research and Education in Pathology (UAREP). Once the equally successful second series was complete, ARP, UAREP, and AFIP decided to embark on a third series, which was then followed by the fourth series. During production of the fourth series of tumor pathology, a concurrent series focused on non-tumor pathology was launched. In preparing for the subsequent series, the two were merged so the fifth series includes both tumor and non-tumor pathology.

Since 2011, when the AFIP merged into the Joint Pathology Center and only available to government and military colleagues, ARP has remained the home for the fascicles. We continue the work of those who first conceived of these volumes.

As with the previous series, our goal is to provide the practicing pathologist with thorough, concise and up-to-date information on the nomenclature and classification; epidemiologic, clinical, and pathogenetic features; and, most importantly, guidance in the diagnosis of the tumors and tumor-like lesions of all major organ systems and body sites.

The ongoing efforts of the editor-in-chief, Editorial Advisory Board, reviewers, editorial and production staff, and individual Fascicle authors ensure that this series is a worthy successor to the previous four.
