Actinomycotic endometritis, often linked to intrauterine devices, requires prompt treatment. Early removal of the device and antibiotics are crucial for effective management and preventing complications.

Area of Science:

  • Gynecologic pathology
  • Infectious diseases

Background:

  • Actinomycotic endometritis is a rare condition.
  • Intrauterine devices (IUDs) are a known risk factor.

Purpose of the Study:

  • To analyze the clinical characteristics, diagnosis, and management of actinomycotic endometritis.
  • To evaluate treatment outcomes and identify factors influencing recovery.

Main Methods:

  • Retrospective review of 7 cases of actinomycotic endometritis from 28,906 endometrial biopsies over 10 years.
  • Histopathological analysis using Gram, Gomori methenamine silver, and Fite stains.
  • Clinical data review including patient demographics, symptoms, IUD use, treatment, and follow-up.

Main Results:

  • Seven cases identified in patients aged 44-85 years, with long-term IUD use (7-44 years).

  • Symptoms included abnormal uterine bleeding, malodor, prolapse, and pelvic inflammatory disease.
  • Histology showed Actinomyces-like organisms with suppurative and inflammatory reactions; culture positive in only one case.
  • Treatment involved IUD removal and antibiotics (10-30 days); delayed IUD removal prolonged infection.
  • Surgical interventions (hysterectomy, salpingo-oophorectomy) were necessary for tubo-ovarian and pelvic abscesses.

    • Conclusions:

    • Actinomycotic endometritis is associated with long-term IUD use and presents with diverse gynecologic symptoms.
    • Prompt IUD removal combined with antibiotic therapy is the mainstay of treatment.
    • Delayed diagnosis or IUD removal can lead to severe complications like abscess formation, necessitating surgical intervention.
