Wilms' tumor of the endocervix

We report a case of primary Wilms' tumor of the endocervix in a 13-year-old girl. The tumor was polypoid, filled the vagina, and was attached to the endocervix by a stalk. Microscopic examination disclosed blastematous, epithelial, and stromal elements characteristic of Wilms' tumor. The patient's kidneys were normal on intravenous pyelographic examination and on palpation at laparotomy, and she has remained free of disease for 9.6 years after hysterectomy.
