Actinomycosis is a chronic suppurative and granulomatous disease caused primarily by Actinomyces israelii.
Recently, due to the widespread use of antibiotics, the incidence of actinomycosis is decreasing and demonstration of sulfur granules is becoming difficult. This situation makes diagnosis of actinomycosis difficult.
In this report, we present a case of actinomycosis which was suspected as a malignant tumor from the clinical and radiogical findings but which was later histopathologically diagnosed as actinomycosis.
