[Oncocytic presentation of a primary epithelioid leiomyosarcoma of the liver].
We report an epithelioid leiomyosarcoma of the liver with oncocytic differentiation. Initially misdiagnosed as an oncocytic endocrine tumor, analysis of the whole liver after transplantation permits rectification of the diagnosis. This observation outlines the fact that oncocytic differentiation is not restricted to epithelial cells but can also be encountered in cells of mesenchymal lineage.
