Synchronous adenocarcinoma and echinococcosis in the same ovary: a rare clinical entity.

Background: Serous adenocarcinoma is the most common subtype of ovarian carcinoma, while ovarian echinococcosis is a rare disease of the female genital system. The simultaneous presence of adenocarcinoma and echinococcosis in the same ovary is extremely rare and little data exist regarding diagnosis and treatment approach.

Materials And Methods: In the present paper, we report a rare case of a 66-year-old Greek Caucasian woman of rural origin, with an adnexal mass, ascitic and pleural fluid. The patient underwent exploratory laparotomy following neoadjuvant chemotherapy, based on positive for malignancy pleural and ascitic fluid cytology results.

Results: Histological examination of the surgical specimen indicated the synchronous presence of echinococcosis and adenocarcinoma in the same ovary.

Conclusions: Ovarian hydatid cyst is extremely rare, but should be suspected in patients with echinococcosis in other organs and those coming from endemic areas. Moreover, the disease could mimic ovarian cancer, as there are no specific symptoms and clinical signs. The coexistence of these two diseases in the same ovary, although rare, is possible. It seems that the presence of the hydatid cyst does not change the treatment approach of the malignancy so that surgery with neoadjuvant or adjuvant chemotherapy, according to the present guidelines, should be administered.
