Background: Primary vaginal clear cell adenocarcinoma (CCA) is a rare gynecological malignancy occurring predominantly in young females with a history of diethylstilbestrol exposure in utero. Vaginal CCA commonly metastasizes to the lungs and the supraclavicular lymph nodes; however we present a rare case of diethylstilbestrol-induced vaginal CCA with cerebral metastases.
Case description: A 43-year-old woman with prenatal diethylstilbestrol exposure and history of vaginal CCA treatment 8 years prior to current presentation noted new onset headache and dizziness. MRI showed an enhancing mass in the right frontal lobe. Histopathology was consistent with CCA.
Conclusions: This case report highlights the necessity of close extended follow-up in patients with a history of vaginal CCA and demonstrates the potential for spread of primary vaginal CCA to the brain.
