The challenging presentation of gastric cancer during pregnancy with krukenberg tumor: a case report.

UNLABELLED

The incidence of ovarian tumors in pregnancy is around 0.05%. Primary ovarian cancer and metastatic malignancy are rare in pregnancy, and women often delayed in diagnosis.

IMPORTANCE

This is the first case ever reported on gastric cancer diagnosed during pregnancy presenting with a Krukenberg tumor and mimic ovarian tumor torsion, cholecystitis. By reporting this case, we could sensitize physicians to be more vigilance of abnormal abdominal pain in pregnant women.

CASE PRESENTATION

A 30-year-old female came to our hospital at the 30th week of gestational age due to preterm uterine contraction and worsening abdominal pain. A cesarean section was performed due to preterm uterine contraction and intolerable abdominal pain suspected to be ovarian torsion. Microscopic examination of the ovarian specimen showed signet-ring cells. The patient was diagnosed with gastric adenocarcinoma at stage IV after complete surveillance. Postpartum chemotherapy consisted of oxaliplatin and high-dose 5-fluorouracil. The patient died 4 months after delivery.

CLINICAL DISCUSSION

Malignancies during pregnancy should be kept in mind while encountering atypical clinical presentations. Krukenburg tumor is rare in pregnancy and gastric cancer is the most common cause. Early diagnosis of the gastric cancer in the operable stage is the key to a better prognosis.

CONCLUSION

Diagnostic examinations for gastric cancer in pregnancy could be performed after first trimester. Treatment should be introduced after balancing maternal-fetal risks. Early diagnosis and intervention are crucial to decrease the high mortality rate of gastric cancer in pregnancy.
