Abstract: Pelvic actinomycosis is a rare infectious disease involving the female reproductive tract. Most of the patients carry an intrauterine device, having some non-specific clinical symptoms and manifestations such as fever, abdominal pain, discharge, and pelvic mass. The diagnosis of actinomycosis highly depends on discoveries of pathology and microbiology. Drug therapy is a basic choice of treatment. Surgeries were applied to severe necrosis and formation of sinus or fistula. Generally, patients with pelvic actinomycosis have a good prognosis.
