A Rare Case of Gestational Choriocarcinoma Presenting as Cornual Ectopic Pregnancy.

BACKGROUND

Choriocarcinoma associated with cornual pregnancy is extremely rare. To our knowledge, only three other cases have been reported in the literature.

CASE: A 38-year-old woman was found to have a left cornual ectopic pregnancy on ultrasound after presenting with abdominal pain, irregular vaginal bleeding, and a positive pregnancy test. Laparoscopy confirmed the diagnosis and she underwent total abdominal hysterectomy. Three weeks later, she presented with vaginal bleeding. A solid ulcerating lesion was found arising from the vaginal wall and biopsy revealed metastatic gestational choriocarcinoma.

CONCLUSION

Careful histopathological examination of the surgical specimen and diligent monitoring of β-human chorionic gonadotropin to zero is crucial to prevent potentially missing this very malignant, but highly curable disease. Early systemic metastases are common and presentation can include bleeding from vaginal metastases.
