Hyperamylasemia with papillary serous cystadenocarcinoma of the ovary.

High levels of serum amylase and CA19.9 were noted in a patient with papillary serous cystadenocarcinoma of the ovary. Electrophoresis identified isoamylases of salivary type. Both markers decreased rapidly after removal of the ovarian tumour. These considerations argue in favor of the early detection of amylase isoenzymes in patients in whom history, objective signs, and routine diagnostic studies fail to disclose a pancreatic disease.
