Gastrointestinal bleeding caused by ileal metastasis of a tubal complete mole: a case report.

BACKGROUND

Tubal hydatidiform mole is known to be an extremely rare disease, moreover, gastrointestinal metastasis from an ectopic complete mole has never been reported.

MATERIALS AND

METHODS

A 33-year-old woman presented with gastrointestinal bleeding. She had undergone laparoscopic left salpingectomy for a tubal complete mole a month earlier. An ileal invasion of mole was identified. The patient received nine cycles of adjuvant methotrexate chemotherapy after small bowel resection and anastomosis. She was been without recurrence 20 months after therapy.

DISCUSSION: Gestational trophoblastic diseases in ectopic pregnancy are rare and gastrointestinal tract metastasis is very infrequent. There have been a few case reports of choriocarcinoma presenting gastrointestinal tract metastasis. To our knowledge, this is the first report of molar pregnancy in a Fallopian tube with ileal metastasis.

CONCLUSION

Ectopic molar pregnancy with gastrointestinal metastasis carries a high risk of intestinal perforation and uncontrollable gastrointestinal bleeding. Despite its rarity, gastrointestinal metastasis should nevertheless be considered a possible cause for gastrointestinal bleeding in ectopic molar pregnancy patients after elimination of the more common etiologies.
