Hepatic angiomyolipoma with concomitant hepatocellular carcinomas.
Angiomyolipoma is a rare lipomatous tumor in the liver. Definitive preoperative diagnosis is becoming easier by the use of ultrasonography, computed tomography, and magnetic resonance imaging techniques. Nonsurgical treatment has been advocated for its benign nature. However, recently we encountered one case of hepatic angiomyolipoma with two concomitant hepatocellular carcinomas on a hepatitis B carrier. Although his serum alpha-fetoprotein was normal, under the above impression these lesions were resected. The pathologic findings showed a typical angiomyolipoma and two well-differentiated hepatocellular carcinomas with marked fatty metamorphosis. This is the first report of angiomyolipoma with concomitant hepatocellular carcinomas in the literature. Nonsurgical treatment of angiomyolipoma in an endemic area for hepatocellular carcinoma should proceed with caution because cases of fat-rich minute hepatocellular carcinomas will make the diagnosis difficult.
