RESUMO
This manuscript commemorates the 100th anniversary of APMIS, highlighting its evolution from a regional journal, founded in 1924 as Acta Pathologica et Microbiologica Scandinavica, to an international platform fostering global collaboration in pathology, microbiology, and immunology. The journal's inception was driven by Ulrik Quensel's vision in 1919, leading to the establishment of the Northern Pathological Society and the launch of the journal in 1924. APMIS has consistently published landmark research, including significant contributions from prominent. These studies have advanced understanding in fields such as pathology, microbiology, and immunology. The journal expanded its scope in the 1970s to include immunology, rebranding as APMIS in the mid-1980s. Recent decades have seen a continued commitment to cutting-edge research and an increasing impact factor. As APMIS transitions to an Open Access model under Wiley, it will be renamed the PMI Journal (Pathology, Microbiology, and Immunology) to reflect its global reach and dedication to scientific excellence. This centennial celebration acknowledges the contributions of editors, authors, and readers, looking forward to future advancements in biomedical research.
