Pelvic actinomycosis in pregnancy: a case report and review of the literature.

The first reported case in Thailand of pelvic actinomycosis during pregnancy is presented. It occurred in a 38-year-old Thai female with a history of IUD wearing for 2 years until the symptoms of intermittent lower abdominal pain. She had a history of postcoital bleeding at 16 weeks' pregnancy and bleeding per vagina during labor at 40 weeks' pregnancy. Speculum examination showed an irregular, friable, easily bleeding mass (3-4 cm in diameter). The specimens of the mass at the posterior fornix were obtained for culture and pathological examination. Right tubo-ovarian complex measured 10 x 4 x 4 centimeters in diameter, extending through the cul-de-sac to the vaginal canal at the posterior fornix, was identified during exploratory laparotomy. Low transverse cesarean section was performed. The pathological diagnosis was actinomycosis of right fallopian tube and ovary. The patient was treated with tetracycline.
