A study of the experience of seven years at the "Hospital General de Arequipa", Teaching Unit of the School of Medicine of Arequipa, reveals an over all incidence of maternal mortality of 1.8 per thousand live births and 1.46% if all obstetric cases are considered (30,726). There is a definite tendency for improvement with maternal mortality descending to 1.16% live births in 1967. The causes of death in order of importance are infection (33%) toxemia (24%) and hemorrhage (15%). The high incidence of maternal mortality is related to socio-economic factors and the inadequate provision of health care at the prenatal stage.

We know that any segment of the genital tract, can be a vice seat position or dystopia, this is a waste of anatomical relationship to its location and its attachment and support structures. Some of these dystopias have greater clinical significance, for example if it happens in the fallopian tubes; however with regard to the uterus, they have sufficient seniority in Gynecology for study.

The authors have studied three cases of dysgerminoma of the ovary occurred between 171 ovarian tumors at the Hospital General of Arequipa, Perú; this number means an incidence of 9.67% between the 31 malignant tumors of the ovary. All the women were between 14-20 years of age and did not present menstrual disturbance; the clinical picture was abdominal distension and pain and none of hem presented virilization; the surgical treatment, in two cases was conservative, however, the verified survival was 3 years in these two patients.

This work represents a clinical-statistical study of the IU E. in the Gynecology Service of the General Hospital of Arequipa and comprises all cases operated from 1965 until 1970 included, totaling 151 cases and a total of 2,414 patients hospitalized in this service, representing a incidence of 6.2%.
