[Pelvic actinomycosis abscess and intrauterine device]

A case of association between IUD and a left tubal actinomycotic abscess is presented. The 45 year old patient was wearing an IUD for five years. The symptomatology was mainly that of pelvic pain with an associated mass in the left iliac fossa. The working diagnosis was that of a digestive tumor or an adnexal mass. The surgical procedure allowed to identify an inflammatory reaction with a pseudotumoral abscess formation in the left fallopian tube. The etiology was confirmed by the pathology and bacteriology reports. Treatment consists in surgical extirpation of the infected structures and long term antibacterial therapy. Actinomycosis is a rare but potentially serious pelvic disease. It may involve various organs and readily takes on the aspect of tumor formation.
