刚才查了一下， 的确有合体巨细胞肝细胞癌的类型。请看如下的个案报道。
Hepatocellular carcinoma, syncytial giant cell: a novel variant in children: a case report.

Abstract

We report the clinicopathologic features of an unusual HCC occurring in an infant who presented with features of Cushing's syndrome due to bilateral adrenal hyperplasia. The tumor is characterized by epithelial syncytial giant cells. Giant cell carcinoma of the liver has been previously reported, but the cells were osteoclast-like (ie, mesenchymal type) and not epithelial type as it is in this patient. We propose to use the term HCC, syncytial giant cell type, to denote this apparently novel lesion.

建议： 再做点工作后，可以发个个案了。
