Actinomycosis is an uncommon but curable chronic infection caused by Actinomyces spp. The cervicofacial region is the most susceptible to infection; however, other sites may also become infected. Data on the current prevalence of this rare disease in Riyadh, Saudi Arabia is lacking. We herein report a case series of four patients with actinomycosis from a single tertiary care center in Riyadh, Saudi Arabia.Three patients presented to us with slowly progressing actinomycosis and one patient developed an acute abdomen, secondary to viscus perforation. Two of the patients had cervicofacial disease, including hard palate actinomycosis. Tissue cultures were sent for three patients; however, tests for actinomycosis were negative. Subsequently, the diagnosis was made through histopathological examination. Therapy involved a combination of surgical resection and debridement and prolonged antimicrobial treatment tailored to each patient.The cases reported in this series highlight the difficulty in diagnosing actinomycosis. For most patients, the diagnosis was delayed or accidentally discovered on histopathological examination. We conclude that increased awareness among physicians is needed for early diagnosis and treatment of actinomycosis.
