Product definition in a case of myoepithelioma.
One case of myoepithelioma was studied by immunohistochemical and histochemical methods to identify the cell products of this tumor. The myoepithelioma had two cell types: plasmacytoid cells and spindle cells. The tumor myoepithelial cells produced the same cell products as did the normal myoepithelial cells but in variable amounts, possibly related to stages of differentiation. As no exocrine cell products could be identified in this neoplasm, it is considered a "true" myoepithelioma.
