[Uterine leiomyoma: pathology and epidemiology].

Two hundred biopsy reports with uterine myoma histopathological diagnosis were studied 67% of the cases were between 41-50 years of age. Premenopausic patients showed an average number of myomas almost three times higher than the postmenopausic women. The most frequent myoma were those within the walls with a size less than 2 cm. Chronic inespecific cervixitis was the most frequent finding in the cervix pathology, with in 1.5% of the cases. In 2 cases (1%) endometrial adenocarcinoma was found. In 60.5% of the cases one or both tubes and ovaries were removed neither case had malignant alterations. In 51 cases (25.2%) the myoma presented some type of degeneration, the most frequent being the cellular type, 16 out of 200, which represented 8% of the cases; it was considered as presarcomatose type. Presurgical clinical behavior is discussed considering the analysis of these figures and the perspectives of the conservative treatment with the use of new no ablative technique.
