The International Journal of Surgical Pathology ( IJSP ) focuses on diagnostic histopathology and publishes 8 issues per year. Articles include original surgical pathology research in all major organ systems, as well as reviews and controversies in the practice of histopathology. Case reports may be considered but should bring new information to the practice of pathology, such as new deceptive morphologic patterns, emerging immunohistochemical markers, or previously unrecognized genetic alterations. “Brief Report” articles are formatted as a letter and may contain a brief description of original research or a case report. The Editorial Board includes subspecialty experts in histopathology from around the world. Proposals for special issues coordinated by a Guest Editor are considered, with emphasis on timely topics on a specific theme or organ system in surgical pathology. ( Note: IJSP does not publish articles describing surgery techniques or clinical treatment, unless the focus is on the resulting histopathology specimens. Basic science articles, especially involving animal models or cell lines, are not considered.) Common topics covered by the Journal include: Novel genetic alterations in tumor types Head and neck and thyroid tumors Soft tissue tumors Genitourinary pathology Gastrointestinal / hepatobiliary pathology Breast tumors and tumor-like conditions Thoracic / pulmonary pathology Gynecologic pathology Brain tumor pathology Immunohistochemical markers for diagnosis and differential diagnosis Novel techniques in the practice of histopathology Reviews highlighting diagnosis and differential diagnosis of emerging and challenging entities in surgical pathology This journal is a member of the Committee on Publication Ethics (COPE). International Journal of Surgical Pathology is an official journal of the Italian Society of Anatomic Pathology and Diagnostic Cytopathology (SIAPEC) and of the Spanish and Hong King Divisions of the International Academy of Pathology (IAP). The following divisions of the IAP as well as additional societies are supporting sponsors of IJSP : Bolivian, Romanian, Brazilian, Australian, Portuguese, and Puerto Rican Divisions of the International Academy of Pathology, the Argentine Society of Pathology, the Brazilian Society of Pathology, and the Korean Society of Pathologists.
