title: [Epithelioid cell. Ultrastructural data during various pathological conditions].
abstract: A morphological study permitted us to show that the epithelioid cell is an active cell, the characteristic vesicles of which seem to be linked to the presence of a glycoprotein substance which passes through the Golgi apparatus and becomes accumlated in the lysosomes owing to their richness in acid phosphatase. A fraction of this substance may be secreted into the extra-cellular medium, without it being possible to determine its precise nature and whether this function is carried out only by this cell.
