[Pelvic tumoral actinomycosis: a difficult diagnosis. Two case reports].

Abstract

Two cases of intra-uterine device-associated occlusive pelvic pseudo-tumoural actinomycosis are presented. A pre-operative diagnosis of ovarian carcinoma was considered in both cases and lead to a wide and difficult surgery. Actinomycosis was confirmed by the postoperative histopathologic examination, and the patients were successfully treated with penicillin. The difficulties and limits of the clinical and histopathological diagnosis are exposed. The interest of the pre and intra-operative diagnosis which can avoid an extensive surgery with high morbidity is highlighted.
