Actinomycosis may be a chronic bacterial infection caused by Actinomyces, Gram-positive anaerobic bacteria. Its symptomatology imitates some malignant pelvic tumours, tuberculosis, or nocardiosis, causing abscesses and fistulas. Actinomycoses are opportunistic infections and need normal mucous barriers to be altered. No epidemiological studies are conducted to work out prevalence or incidence of such infections. Objective. To analyse the clinical cases of pelvic actinomycosis reported worldwide, to update the knowledge about the disease. Methods. a scientific review of worldwide pelvic actinomycosis cases between 1980 and 2014 was performed, utilising the PubMed, Scopus, and Google Scholar databases. the subsequent information was analysed: year, country, sort of study, number of cases, use of IUD (IUD), final and initial diagnosis, and method of diagnosis. Results. 63 articles met the search criteria, of which 55 reported clinical cases and eight reported cross-sectional studies. Conclusions.
