![his subpleural lesion consists mostly of pigmented scar tissue with gray-tan tumor seen predominantly at the periphery.The visceral pleura overlying the tumor is retracted due to traction by underlying scar tissue. This is a good example of what has been called "scar carcinoma". In almost all cases of this type the scar is not a pre-existing lesion but rather represents a desmoplastic reponse to the tumor cells. The basal visceral pleura is involved by tumor[4]](/images/9/97/Lung_adenocarcinoma1.jpg)
