An extremely rare cause of acute abdomen in pregnancy: ruptured pancreatic mucinous cystadenocarcinoma.

Pancreatic cystadenocarcinoma is an extremely rare neoplasm in pregnancy. To our knowledge, there have been 2 published cases of pancreatic mucinous cystadenocarcinoma (PMC) during pregnancy in the literature; one of which was reported to have ruptured into the abdominal cavity. We present a second case of ruptured PMC resulting in acute abdomen in 36 weeks of pregnancy. Rupture of mucinous cystic neoplasms of pancreas including PMC should be remembered in acute abdomen during pregnancy.
