My choice for Squamous Cell Carcinoma was guided by the central location of the tumor. To me, that didn’t look like the cavity you’d get with abscess but a huge tumor.

I don’t think it was cavitary; I think that was just the bronchus. I think abscesses tend to be smaller, and wouldn’t affect the surrounding parenchyma much. I wasn’t super confident in picking squamous cell carcinoma, but I did know that squamous cell carcinoma tends to be a centrally-located lung tumor.
