Thanks Vladimir. vtkExtractCells filter works out for me.

I think there's no way to do that directly. The reason is, probably, that
all the cells are enumerated, so if you remove a particular single cell,  
have to re-index all cells after it in the data structure.

The easiest way I've found so far is to use vtkExtractCells filter to  
all cells, except those you want to remove, into a new dataset.

Alternatively, you can apply a dirty hack by edge-collapsing your cell  
first, so
it disappears visually, then use some cleaning filter to actually remove
