title: [Pelvic actinomycosis simulating adnexal malignant tumor].
abstract: The purpose of this report is to describe the case of a 35-year-old patient admitted to the National Oncology Institute in Rabat, Morocco for pelvic pain and deteriorating general status ongoing for 8 months. Clinical and ultrasonographic examination showed a heterogenous mass measuring 7 cm in maximum width located inferior and lateral to the inferior aspect of the right side of the uterus. These findings were suggestive of a malignant tumor of the right ovary. Ovariectomy and omentectomy were performed. Histological examination of surgical specimens demonstrated right tubo-ovarian actinomycosis associated with peritonitis. Genital tract actinomycosis is an uncommon finding in women of childbearing age. It is due to colonization by a pyogenic bacteria (Actinomyces) usually secondary to a gastrointestinal infection, e.g. ileocecum, and sometimes in association with the presence of an intrauterine device or foreign body. Based on this case report, the authors discuss abdominopelvic actinomyocosis with emphasis on tumor-like findings that can lead to misdiagnosis by clinicians and radiologists.
