I read with great interest the work by Fang, Zhou, Jin and Hu, dealing with perivascular epithelioid cell tumour (angiomyolipoma) of the liver[1]. It is right that, in mesenchymal tissues, the tumour is common in the uterus. The most frequent localization generally is, however, in the kidney[23]. In the liver, 110 cases had been described by 1999[3].
It is true that the malignant cases are much fewer.
Our interest in this entity was arisen, when we scrutinized a hepatic tumour, described from our department as an oncocytic adenoma[4]. However, the tumour later turned out to be positive for the melanocytic marker HMB-45 and is in fact a perivascular epithelioid cell tumour. The journal refused to publish the revised diagnosis!
