Pregnant woman with vaginal bleeding

A 28-year old woman, 28 weeks pregnant, sought medical attention when she first experienced vaginal bleeding. She did not have a history of uterine contractions. Physical examination revealed a well-developed, obviously pregnant woman in no acute distress, with active oozing of blood from the vaginal outlet. Pelvic examination revealed a large, exophytic mass on the left side of the cervix. Bright red blood was present in the endocervical canal. Radiologic examination demonstrated a 5 cm mass involving the endocervix and ectocervix. There was no evidence of direct tumor extension into the parametrium. The pelvic lymph nodes were slightly enlarged, raising the possibility of nodal involvement by a tumor. A radical hysterectomy was performed, following the delivery of a healthy baby by C-section at 31 weeks gestation.
