[Genital actinomycosis and pelvic abscesses in a woman with a 13-year-old intrauterine device].

A 55-year-old woman who had had the same intrauterine device (IUD) for 13 years was referred to the gynaecology outpatient clinic due to constitutional symptoms, abdominal pain and vaginal discharge. Diagnostic imaging showed multiple pelvic abscesses, and severe chronic endometritis with Actinomyces was found in an endometrial biopsy. The patient underwent surgical drainage of the accessible abscesses and started long-term antibiotic treatment. This case report illustrates that actinomycosis is an important differential diagnosis in symptomatic women with IUD and suspected gynaecologic malignancy.
