Liver Abscess With a Markedly High Level of Carbohydrate Antigen 19-9
نویسندگان
چکیده
Serological tumor markers are useful for detection of malignancies and evaluation of disease progression. However, some markers are rarely elevated in patients with benign diseases and without malignancies. We herein present a case of a liver abscess with a highly elevated carbohydrate antigen (CA 19-9) level in both the serum and abscess fluid. The serological level of CA 19-9 decreased with treatment. Although CA 19-9 is known to be a specific tumor marker, high serum levels of CA 19-9 can be observed in patients with pyogenic liver abscesses. CA 19-9 may also be a marker for treatment response in patients with liver abscesses.

Carbohydrate antigen 19-9 is most valuable as a serum marker for pancreatic and biliary cancer, but increased concentrations occur in several other gastrointestinal malignancies. A carbohydrate antigen 19-9 value of >1,000 U/ml usually indicates a digestive cancer and has been reported to have a specificity greater than 99% for pancreatic cancer; nevertheless, false-positive results owing to be...

Here we report the first case of carbohydrate antigen (CA) 19-9-producing early gastric adenocarcinoma arising in polyp. A solitary pedunculated polyp lesion of the stomach, measuring 26 × 20 × 20 mm, was noticed in a 76-year-old Japanese woman due to an abdominal disorder, associated with a markedly high serum CA19-9 level (2,172.6 U/ml). After endoscopic mucosal resection was performed, the C...

Elevated carbohydrate antigen 19-9 (CA19-9) beyond 1000 U/L occurs in nonneoplastic conditions which is causing questioning of the use of CA19-9 as a marker for screening. We report a case where a 51-year-old male with Mirrizi Syndrome (MS) presented with markedly increased CA19-9 level (4,618 U/mL). MS is a rare complication characterized by compression of the common bile or hepatic duct cause...

Serum Carbohydrate Antigen, CA19-9, is a carbohydrate antigen whose usage -as a tumor marker- in pancreatic and bile ducts malignancies is commonly increasing. Sensitivity and specificity of this antigen in the diagnosis of malignancies is 70-90% and 68-91%, respectively. CA19-9 can also rise in other disorders and in few of benign conditions including cholangitis, due to other causes, e.g. cho...
متن کاملAcute Cholecystitis with Significantly Elevated Levels of Serum Carbohydrate Antigen 19-9
Serum carbohydrate antigen 19-9 (CA 19-9), a marker of malignant tumors, is generally slightly elevated in benign conditions. We report a case of acute cholecystitis with a significantly elevated level of serum CA 19-9 based on positron emission tomography (PET)-computed tomography (CT) findings. A 65-year-old woman presented with abdominal pain and fever. A CT image revealed an enlarged gallbl...
