[Pelvic actinomycosis: two cases]. / Actinomycose pelvienne: à propos de deux cas.

INTRODUCTION: Actinomycosis is a chronic suppurative granulomatous disease caused by different Actinomyces species, mostly bacillus: the Actinomyces israeli. The pelvis location of this infection is rare. OBSERVATIONS: We report two cases of actinomycosis that were diagnosed after the surgical treatment of a suspected ovarian tumor and a suspected acute peritonitis. Diagnosis in both cases was based on the histopathologic findings. CONCLUSION: The incidence of pelvic actinomycosis is increasing since 1960 related to the frequent use of intra uterine device. The clinical symptomatology is not specific, simulating a neoplastic or an inflammatory process. The treatment combines operative and antibiotic therapy.
