ABSTRACT
Malignant transformation of struma ovarii is exceptional (less than 1%). The histolological diagnosis of malignancy is difficult especially in the well differentiated forms. Immunohistochemistry is highly contributive in the anaplastic forms. The prognosis is relatively favorable except for the metastatic and undifferentiated forms. We report a case of malignant struma ovarii with metastasis observed in a 65-year-old woman who died rapidly from her disease. In light of this observation, we discuss the diagnositic, management and outcome features of these particular tumors.

Ectopic localization of oxyuriasis is rare and frequently does not cause clinical problems. It has been reported in the vagina, endometrium, fallopian tube, peritoneal surface and ovary; In these localizations it often causes pseudo-tumoral granulomas. The aim of our study was to describe etiopathogenic and clinical criteria of this rare pathology. We report one case of endometrial enterobiasis which developed in a 28-year-old women and two cases of tubo-ovarian pseudotumoral abscesses containing the ova of enterobius which appeared as a latero-uterin mass in women aged 28 and 38 years. Enterobius vermicularis may cause tubo-ovarian abscess formation with necrotizing epitheloid granulomas mimicking tumors. Antihelminth therapies are successful.
