BACKGROUND Hepatic angiomyolipoma (HAML) is a rare hepatic mesenchymal tumor. This study was designed to explore its clinical features. METHODS Clinical data from 26 patients who had been pathologically confirmed with HAML and had received surgical resection at our hospital were analyzed retrospectively. RESULTS HAML was seen more frequently in females (18/26) in this series, and most of the patients presented no significant symptoms except for one who had a spontaneous rupture hemorrhage. Serum alpha-fetoprotein (AFP), carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) were negative in all patients. Imaging presentations were diverse. Pre-operative diagnosis was made in only 3 patients. Pathological study showed that the tumor was composed of adipose tissue, smooth muscle and blood vessels in different proportions. One patient showed hepatic vessel invasion. HMB-45 immunohistochemical staining was positive in all tumors. All patients underwent surgical resection without significant complications. Except for one patient who died 14 months after operation because of recurrent disease, no tumor recurrence was observed in the remaining 25 patients during a 2-3 years follow-up. CONCLUSIONS Pre-operative diagnosis of HAML is difficult. There are potential risks of spontaneous rupture and malignant transformation. Surgical resection is the treatment of choice for HAML.

D009363 Neoplasm Proteins Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.
