Background:
Hepatic angiomyolipoma (HAML) is a rare liver tumor. This paper summarized the clinical, radiological and pathological features of HAML.
Methods:
Seventeen 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.
Results:
There 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.
Conclusions:
Preoperative 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.
