[The lung and benign diseases of the ovary].

Two main benign diseases of the ovary which can simulate advanced stage cancer of the ovary are described. The first is Meigs' syndrome, a triad of benign ovarian tumor, usually an ovarian fibroma, ascitis, and pleural effusion with complete disappearance of serous exsudative effusions with surgical resection of the ovarian tumor. The second is ovarian hyperstimulation syndrome following ovulation induction with exogenous gonotropins for the treatment of infertility. This syndrome associates significant ovarian enlargement, hyperestrogenism and latent or clinically patent serous exsudative effusions; it usually resolves with suggestive measures and rest.
