Abstract
- Objective To explore the histological morphous,immunohistochemical and clinical features,differential diagnosis and prognosis of hepatic inflammatory angiomyolipoma(AML).Methods The clinical and pathological data of 5 patients with inflammatory hepatic AML were retrospectively analyzed followed by follow-up.The typical tissue was observed by immunohistochemical staining.Results Five patients(1 male and 4 females) aged from 21 to 48 years.Tumors were situated in left lobe of liver in 3 patients,and in right lobe in 2 patients.The tumors had a diameter of 5.5-10.0cm averaged 7.5cm.Generally,the tumors were grey-white on cut surface,without hemorrhage,necrosis and cystic degeneration.Microscopically,the tumors were consisted of spindle and epithelioid myocytes,irregular thick-walled blood vessels and adipose tissue in different proportion.A prominent infiltration of inflammatory cells,including lymphocytes,plasmocytes and histiocytes,in the background was noted in all cases.No obvious atypia and mitotic figure,and no hemorrhage,necrosis and cystic degeneration were noted in the tumor cells.It was immunohistochemically revealed that the tumor cells of all the 5 patients were positive in HMB-45,Melan-A,SMA and Vimentin,while negative in CD21,CD35,CK18,CK19,hepatocyte paraffin-1,AFP,EMA and CK.All the patients were undergone local hepatectomy without recurrence during a 3 to 9 years follow-up.Conclusion Inflammatory hepatic AML is one of the sub-types of AML,demonstrating a similar benign biologic behavior with classical AML.
