"Histopathology"
"Histologically desmoplasia may involve very few cells or an abundance of them. The oligocellular form comprises a very low number of spindled tumour cells, thinly dispersed (usually as single cells) in a fascicular pattern, separated by bundles of sclerotic collagen, forming an extensive extracellular matrix. Whereas, the multicellular form demonstrates a large number of cells, including fibroblasts, vascular and immune cells, with a general lack of extracellular stroma 1,2."
