'''Desmoplasia''' | '''Desmoplasia''' is the formation of fibrous connective tissue.<ref>URL: [http://www.merriam-webster.com/medical/desmoplasia http://www.merriam-webster.com/medical/desmoplasia]. Accessed on: 2 May 2013.</ref> It is also known as the '''desmoplastic response''', '''desmoplastic stroma''', '''desmoplastic stromal response''', and '''stromal response'''. | ||
It is a stromal change that in the context of dysplasia supports the diagnosis of an invasive [[carcinoma]]. | |||

Features: | |||
* | *Increased stromal cellularity - '''key feature'''. | ||
* | **Large (plump) spindle cells (fibroblasts)‡ with (large) nuclei that are pale in relation to the tumour cells. | ||
*Edema - pale spaces between the cells - may be apparent at low power.<ref>{{Ref TPoSP|15}}</ref> | |||
Note: | |||
*‡ Large (plump) spindle cells: the nuclei have approximately the width of a resting lymphocyte. | |||
