Vaginal Adenocarcinoma in a Gravida with Prenatal DES Exposure

Abstract

The article presents a case of a young pregnant woman with vaginal carcinoma who had been exposed to diethylstilbestrol (DES) in utero. Surgical excision of the lesion was attempted but failed. Interstitial irradiation was then applied and proved successful. The patient's infant, as well as two subsequent children, were delivered by cesarean section after normal pregnancies. There was no evidence of metastatic disease or recurrence in 11½ years following the initial diagnosis. Since 1965, a rising incidence of vaginal adenocarcinoma in women who were exposed to (DES) in utero has been reported. These women should be examined regularly after menarche for prompt evaluation and treatment of precancerous lesions such as adenosis, cervical erosion or transverse ridges. Since most of these patients are young, a conservative treatment is recommended. Extensive surgery and pelvic irradiation is indicated, however, in the cases of widespread disease.
