title: Intrauterine device-associated actinomycosis simulating pelvic malignancy.
abstract: We describe pelvic and rectal actinomycosis in a patient with an intrauterine contraceptive device. The presentation was that of an indolent, noninfectious process which mimicked a pelvic malignancy. As in many cases of pelvic actinomycosis, the diagnosis was not suspected preoperatively. Moreover, suppurative disease progressed despite removal of the intrauterine device. In patients who have intrauterine contraceptive devices or who have had them removed recently, abdominal pain, recurrent vaginal bleeding or adnexal masses should prompt a diligent search for potentially pathogenic actinomyces in the genital tract.
