well it has to be Silicosis cos all the description is of PAP (Pulmonary Alveolar Proteinosis) which also looks like Silicosis but in silicosis normally on Autopsy we dont find a Golden appearence. this picture is more consistent with Lipid Pneumonias which is divided into 2 types Endogenous + Exogenous

it was quick 
as i remember that is squamous cell carcinoma, which obstructs bronchi and cause lipid pneumonia - destruction of lung tissue distal to the carcinoma
i just never heard about it before this q
