Dedifferentiated chondrosarcoma metastasizing to the pancreas in pregnancy

Acute abdomen in pregnancy can present difficulties in both diagnosis and treatment. In this patient the presentation of an acute abdomen was due to some intraperitoneal hemorrhage complicating a pancreatic metastasis from a primary dedifferentiated chondrosarcoma arising from the right iliac bone. Neither the primary nor the secondary growths had been suspected previously.
