Cervical adenocarcinoma in situ recurring as vaginal adenocarcinoma 16 years after hysterectomy.

ABSTRACT

We report a case in which a vaginal adenocarcinoma was discovered in a 67-year-old woman 16 years after hysterectomy for cervical adenocarcinoma in situ. Both the vaginal and cervical lesions exhibited morphologic and immunohistochemical (CDX2-positive) features of intestinal differentiation. Linear array human papillomavirus genotyping demonstrated the vaginal adenocarcinoma to contain human papillomavirus 45. We believe the vaginal adenocarcinoma to be related to the cervical adenocarcinoma in situ and to represent recurrence of this. This is an extremely rare phenomenon with, as far as we are aware, only one previous report in the literature.
