[Morphological correlations between endometrial hyperplasias, uterine leiomyoma and ovarian associated lesions]

Morphological evaluation and correlation of endometrial hyperplasias, leiomyoma and ovarian estrogen producing lesions. 390 specimens of hysterectomy associated or not with ovarectomy were processed by routine technique and sections stained by H&E staining. 316 cases presented different degrees of endometrial hyperplasias associated with leiomyoma. In 117 from 170 cases the ovary presented estrogen secreting lesions (follicular cyst, polycystic ovary, stromal hyperplasia, granulosa cell tumours). The highest frequency of the uterine and ovarian lesions was in the decades 41-50 years, and 31-40 years. Leiomyoma and endometrial hyperplasia, develop in a hormonal context, most frequently characterized by micropolicystic ovaries. The risk is higher in the perimenopausal period. The most frequent type is simple hyperplasia suggesting a rare progression to highest grades and a possible protective role of leiomyoma as target tissue which capture estrogens.
