Vaginal metaplasia of the bladder associated with ectopic ureterocele. A clinicopathologic study of two cases.

We report two cases of vaginal metaplasia associated with ectopic ureterocele with complete ureteric duplication. The theories proposed to explain this metaplastic change are briefly reviewed. This previously unreported association with ectopic ureterocele suggests that this may an example of heteroplasia, and that this relationship could be more than casual.
