Three cases of ovarian actinomycosis with literature review.

Background: Actinomycosis is an actinomycete infection, a rare zoonotic disease characterized by chronic suppurative inflammation and granulomatous inflammation. When injury occurs to the mucosa where parasites are present, actinomycetes can invade the mucosa. Widespread use of intrauterine devices (IUDs) has increased the incidence rate of pelvic actinomycosis among women.

Primary vaginal clear cell adenocarcinoma accompanied by Herlyn-Werner-Wunderlich syndrome without prenatal diethylstilbestrol exposure: a case report.

We report a rare case of a 40 years old woman with primary vaginal clear cell adenocarcinoma (CCA) accompanied by Herlyn-Werner-Wunderlich syndrome (HWWS) and without any prenatal diethylstilbestrol exposure. Pathological results indicated that the CCA was surrounded by adenosis and that there was a benign to malignant transformation of several glands in the epithelium, so the CCA was believed to have arisen from the adenosis. The literature review disclosed that genitourinary anomalies might be associated with an increased risk of adenocarcinoma, but the mechanism was not clear.
