Lungs Adenocarcinoma versus Bronchoalveolar Carcinoma


Bronchoalveolar carcinoma is a subtype of adenocarcinoma of the lung, the point is both occur peripherally in non-smokers, how to differentiate between them in exam?

I have encountered a question in USMLE world and the correct answer was adenocarcinoma not bronchoalveolar (which is clearly stated in FA that it isn't linked to smoking) based on a non-smoker peripheral lesion in the lung that proved malignant!!!!!

What do u guys think?

Peripheral mass lesion in a nonsmoker=Adenocarcinoma
Peripheral lesion with appearance of pneumonia-like consolidation on CXR= Bronchoalveolar carcinoma.

Bottomline is, don't pick bronchoalveolar carcinoma unless an obvious hint is given (x ray appearance, histologic appearance).
