We report a case of abdominal actinomycosis in a young woman wearing an int
rauterine contraceptive device. The patient presented with right lower abdo
minal pain. A diagnostic laparoscopy was performed. Intraoperatively two pe
rforations of the sigma were detected, a sigmoidectomy was performed. Posto
peratively no problems occurred. Histology revealed an abdominal actinomyco
sis. In the literature only some case reports are published dealing with ab
dominal actinomycosis. Women wearing intrauterine contraceptive devices see
m to have a higher risk of actinomycosis. In unproblematic cases antibiotic
therapy is the treatment of choice. In cases of doubt as in our case surge
ry is recommended to confirm the diagnosis.
