Key Points

Describe a case of uterine actinomycosis mimicking endometrial cancer in a patient with prolonged intrauterine device (IUD) use and identify the causative bacterial species via microbiome analysis.
Evaluated a patient presenting with an intrauterine mass suspected to be endometrial cancer on imaging following long-term IUD placement.
Performed cytological evaluation and bacterial flora analysis on an intrauterine lavage specimen.
Cytological examination excluded malignancy and confirmed a diagnosis of uterine actinomycosis.
Microbiological bacterial flora analysis detected Actinomyces mediterranea as the causative organism rather than the typical pathogen Actinomyces israelii.

Implication

Case report reveals Actinomyces mediterranea mimicking endometrial cancer in a long-term IUD user, highlighting the diagnostic value of microbiome analysis for uterine actinomycosis.

Abstract

背景：放線菌症は主に嫌気性グラム陽性桿菌Actinomyces israelliによる慢性化膿性肉芽腫性感染症であり，子宮内避妊器具（intrauterine device：IUD）の長期留置と関連が示唆されている．今回画像上は子宮体癌が疑われたが細胞診で子宮放線菌症を診断し，菌叢解析で別の起因菌が示唆された 1 例を経験した．
