Diagnosis and treatment of hepatic angiomyolipoma.

BackgroundHepatic angiomyolipoma (HAML) is a rare liver tumor. This paper summarized the clinical, radiological and pathological features of HAML.MethodsSeventeen cases of HAML were analyzed retrospectively. All patients were subjected to surgical resection of tumor, one of which was performed emergency surgery because of hemorrhage of tumor.ResultsThere are 13 females and 4 males, most of whom were asymptotic except 4 had minimal abdominal discomfort. US, CT and/or MRI were taken and corresponding data was comprehensively analyzed with other clinical signs and symptoms. Correct preoperative diagnosis was able to be achieved in 9 patients. Pathological analysis and immunohistochemistry of HMB-45 was used as final diagnosis. All patients were followed up and survived without recurrence.ConclusionsPreoperative diagnosis of HAML can be benefited from comprehensive analysis of clinical manifestations. The malignant potential and fast growth of tumor suggested surgical removal of tumor while it was diagnosed.
