Myoepithelial carcinoma arising in a benign myoepithelioma: immunohistochemical, ultrastructural, and flow-cytometrical study.

abstract：:Mitochondrial abnormalities have received relatively little attention in the ultrastructural evaluation of paragangliomas. Review of the few literature references dealing with this issue, however, reveals that quantitative and qualitative changes of these organelles occur in that context. A bladder paraganglioma is de...
