Cytologic findings in female and male offspring of DES treated mothers.

Data on vaginal, cervical, and endocervical samples and urine specimens of 84 female offspring exposed to diethylstilbestrol in utero and 43 controls have been presented. The colposcopic and histopathologic findings were correlated with the cytologic findings. Our preliminary findings indicate that the cytologic technique is reliable as screening test for vaginal epithelial changes in the DES-exposed females provided the sampling procedure is adequate. In 79 male patients, 42 DES-exposed and 37 controls, the pre-massage urine, the prostatic fluid, the post-massage urine and aspirate of cysts of the epididymis when existing were examined by cytologic techniques. No tumor cells were found in the cytologic specimens of the exposed and unexposed male and female offspring.
