Highly-illustrated pathology atlases that provide guidance in the diagnosis of tumors and tumor-like lesions

Since 1921, the American Registry of Pathology (ARP) and its associated entities, ARP Sciences and ARP Press, have worked to serve the needs of the U.S. military and civilian populations by advancing health and forensic sciences. Since 2001, ARP’s work has evolved and it became the primary partner to the U.S. Department of Defense in developing the world’s most sophisticated toxicology and DNA testing and forensics laboratory.

ARP Press provides medical publications to assist medical students, residents, fellows, pathologists, physicians, and researchers with their work. Their major series include ARP-AFIP Atlas of Non-Tumor Pathology, Series I and ARP-AFIP Atlas of Tumor Pathology, Series IV. In addition, they have a series of Special Publications on various topics such as Advanced Laboratory Methods in Histotechnology & Pathology.
