From what I understand of the term, histotoxic refers to an inability for cells to take up and use oxygen which is delivered to them, in spite of there being oxygen in abundance to use. You would normally get a situation like this, if the cell is incapable of taking on oxygen, because it has been blocked up with carbon dioxide or monoxide or something like that.
So, for example, you could have a decent amount of oxygen available, but if the cells that oxygen is trying to reach have been blocked up by the presence of carbon gases of various sorts, the oxygen will not be taken up, which causes obvious problems.
