Elevated carbohydrate antigen 19-9 in patients with true (epithelial) splenic cysts - Rare or Undiscovered?
M Soudack | A Ben-Nun | C Toledano
antigen 19-9 is a well known marker for pancreatic adenocarcinoma.
However, its limitation is its nonspecificity, because
elevated levels may be encountered in other gastrointestinal
disorders, both benign and malignant. The following
case is a patient with a true (epithelial) splenic cyst
with elevated serum levels of carbohydrate antigen 19-9.
