Answer:

caseous necrosis

Explanation:

The pathologic process that most likely occurred to this nodule would be caseous necrosis. This occurs at the time of death of a some cells but it is a very unique scenario in which the cell maintains a soft and white proteinaceous dead cell mass, just like in this scenario. This type of cell death usually occurs in lymph nodes but can occur in any cell in the body including in the lung.
