Primary hepatic mucoepidermoid carcinoma:clinicopathologic analysis of 4 cases and literature review
摘要
Abstract
Purpose To investigate the clinicopathological features of primary mucoepidermoid carcinoma of the liver(PMCL).Methods The history,clinical data,pathological diagnosis,differential diagnosis,treatment and prognosis of 4 patients with PMCL were retrospectively analyzed.Results All four tumors were located in the left half of the liver and were sol-itary.Microscopic examination showed that tumor cells were composed of three types of cells:epidermal like cells,interme-diate cells,and mucinous cells,with varying proportions.Im-munophenotype:tumor cells showed diffuse strong positivity for CA199 and CK19,while mucous cells showed focal positivity for CEA.CK7 mainly expressed in epidermal like cells and mucous cells,while CK5/6,p40,and p63 expressed in epidermal like cells and intermediate cells.Special staining with AB,PAS,and mucin carmine confirmed the presence of mucous cells,Ki67 proliferation index ranged from 30%to 40%.FISH testing:no MAML2 gene breakage or rearrangement was detected in 4 cases of PMCL,and MAML2 gene amplification occurred in 1 case of tumor.Conclusion The incidence of PMCL is low and present with non-specific clinical manifestations,which often leads to misdiagnosis.The diagnosis should be differentiated from bile duct adenocarcinoma and adenosquamous carcinoma.Moreover,there is currently no established standard treatment for PMCL and has a poor prognosis.关键词
