Abdominal wall actinomycosis simulating a malignant neoplasm: Case report and review of the literature.

Abdominal wall actinomycosis is a rare disease frequently associated with the presence of an intra uterine device. We report on a case of a 47-year-old woman who had used an intrauterine device for many years and had removed it about a month prior to the identification of an abdominal wall abscess caused by Actinomyces israelii. The abscess mimicked a malignancy and the patient underwent a demolitive surgical treatment. The diagnosis was obtained only after histopathological examination. Postoperatively, the patient developed an infection of the wound which was treated with daily medication. The combination of long-term high dose antibiotic therapy with surgery led to successful treatment.
