Mesonephric adenocarcinoma of the vagina with a 3-year follow-up.

BACKGROUND

Mesonephric adenocarcinoma of the vagina is exceedingly rare, with only one well-documented case in the literature. Little is known regarding clinical presentation, pathological characteristics, therapy, or prognosis of the vaginal mesonephric adenocarcinoma.

CASE: A 55-year-old woman presented with a polypoid mass at the right vaginal apex, extending to the right paravaginal tissue. The tumor was an adenocarcinoma with ductal and tubular pattern arising in a background of mesonephric remnants. Tumor cells showed immunoreactivity for pankeratin, epithelial membrane antigen (EMA), and calretinin. The right fallopian tube and one paravaginal lymph node were positive for metastases. The patient is disease-free 3 years after surgery, radiation therapy, and chemotherapy.

CONCLUSION

We report the second case of mesonephric adenocarcinoma of the vagina with metastasis to the right fallopian tube and to one paravaginal lymph node.
