At levels greater than 1000 U/ml, the tumor-associated antigen CA19-9 has a specificity approaching 100% for malignant disease. A 67-yr-old woman with known cholelithiasis presented with painless jaundice and a CA19-9 of 1320 U/ml. The diagnosis of Mirizzi's syndrome was made at laparotomy, and the postoperative level fell rapidly to normal. Mirizzi's syndrome should be included among the few benign disorders which can yield such elevations in the CA19-9.
