Analysis on the clinicopathological characteristics of hepatobiliary mucinous cystic neoplasms / 肿瘤研究与临床

ABSTRACT

Objective To study the clinicopathological characteristics of hepatobiliary cystic neoplasms(cystadenoma and cystadenocarcinoma)in order to improve its diagnostic and therapeutic accuracy.Methods A retrospective analysis was done on the clinical materials of 9 cases of cystic biliary tumors hospitalized in the People's Hospital of Rizhao City from May 1993 to May 2007.All cases were confirmed by operation and pathologic biopsy.Results Six cases were biliary cystadenoma with muhilocular cyst.The other three cases were biliary cystadenocarcinoma,two with single cyst and one with multilocular cyst.Of the three cystadenocarcinorna,two cases had mural nodules and one case had papillary excrescences and cystic wall thickening.Irregular thickening of internal sept.was shown in the multilocular cyst cases.Two had calcification.Enhancement of the wall.internal septa and nlasses were seen in all the malignant tumors on CT scans. Metastatic lymph node was found in one cage. Conclusion There were no special clinical characteristics in difierentiation between hiliary cystadenoma and cystadenocarcinoma. Single cyst, mural nodules and papillary excrescences,irregular thickening of cystic wall and internal septa,coarse calcification and metastatic lymph node increase the likelihood of the diagnosis of the malignant tumors.But the diagnostic differentiation between cystadenoma and cystadenocarcinoma depends on pathology.
