the bottom line fr mesothelioma is exposure , the'll always mention that in the ques. the pt may or may not be a smoker .

hi spring09...asbestos exposure also causes adenocarcinoma....the question should say in my view columnar like cells(epitheloid form of mesothelioma) ...not columnar cells (which refers to adenocarcinoma.....

[ArchivalUser]

its cc mesothelioma due to location and also long villi which are present in meso as compared to short in adeno

yes i agree with long villi ....but i cant find any article which says columnar cells in mesothelioma...

[ArchivalUser]

ur right yeabiruh...
this is wat goljan says ... asbestos + smoking = primary lung cancer(most common)
but he also says , meso typically takes 25-30 yrs , while adeno takes about 10 yrs to develop.
i'm confused , if i go by the history !!

No offense but question is not written properly...what i mean is that its part from here and part from there put togather with dual diffrentation.....I would also answer this as mesothelioma...I look at as this being 75% percent toward mesothelioma as compare to 25% toward adenocarcinoma.... If we get qeustion like these in USMLE...then we'll all end up pulling our hair all day at the exam...Yeabiruh is right
Adenocarcinoma - columnar cells and cubiodal epithelium in mesothelioma...again i hope i didnt hurt anyone's feeling...

timbucktoo you are right. We have to pull our hair :-) But probably these type of question will be less than 5 in the whole exam !!! I don't know. Like you will see at NBME there are lots of controversial questions. Anyway, I just copy and paste the q from qBank. This question made me really really confused.

From UWorld:

Cells of adenocarcinoma, which can show glandular or papillary elements, have short and plump microvilli that distinguish adenocarcinoma from mesothelioma
