CA-19-9 PRODUCTION BY A CYSTADENOMA WITH MESENCHYMAL STROMA OF THE COMMON HEPATIC DUCT - A CASE-REPORT

A case of a CA 19-9 producing cystadenoma with mesenchymal stroma orig inating from the common hepatic duct is presented, with a review of th e literature. The findings of ultrasound and CT scans and the endoscop ic retrograde cholangiopancreatography picture allowed the establishme nt of a confident pre-operative diagnosis. Although there was an eleva tion of CA 19-9 serum levels, the resected specimen did not show any m alignant focus at pathologic examination. After surgical excision, CA 19-9 serum levels returned to normal.
