RESUMO
Since 70 years ago, the possibility that the etiology of Gravidic Toxemia is inmunologic has been studied. Several researchers agree in the disminution of the levels of IgG with no modifications on the levels of complement fractions. The determination of IgA, IgM, IgC, C3 and C4 was made on fifteen pacients with gravidic toxemia and fifteen pacients that presented no complicated pregnancy. The results are the same as the reported facts like disminution of IgG, it was observed also, a disminution on the complement fractions C3 and C4. The research let us stabblish the posibility of a sikness caused by immune complexs having as an antigenic stimulations the trofoblast.

Benign tumors of smooth muscle are relatively common in the genitourinary and gastrointestinal tracts. Retroperitoneal leiomyoma is a rare. A case of a 37 year old woman with diagnostic of leiomyoma of the uterus with the finding of retroperitoneal leiomyoma is presented.

A case of a 41 years old woman with a benign mesothelioma of the superficial epithelium of the ovary, is presented. The tumor was expanded at the bottom of the cul de sac. It did not invade the rectum, uterus or vagina and it has not been recurrent, and there are not metastasis after y 6 years post operatively. Morphologically, the neoplasia is created by papillae invested with cells of mesothelial appearance, which contain a small amount of glycogen and acids mucopolysaccharide. With immunoperoxidase keratin is shown and at the electronic microscope some desmosomes and microvillus, are identified. The histogenesis of the tumor examined, and the differential diagnosis between mesothelioma and superficial papillary carcinoma of the ovary, is considered.
