This video was more informative and interesting than my whole histology course in the 2nd year

Thank you, that is really encouraging to hear. Spread the word!

Thanks for the video...
Very informative to students..

[@shaharyarsheikh6878]

Very nice description but please remove music from the start and ending , it gets very loud in contrast to your own voice . Blew my speakers

[@Christynmaine]

I’m assured my pulmonary granulomas are not cancerous but they lit up under a PET scan. Does this mean I am infectious? What else can cause this?

[@Rachie-nj3oi]

So I've just been told I have glanduloma from a chest xray.
Said it might be tb or from an old infection.
I never had my tb vaccination.
Do I need to worry about this? I'm in pain everyday for the last 4 years. Is there any treatment or does it decrease life expectancy?

[@cherylcampbell7495]

I have one in my brain from valley fever, at age 12. It’s in a hard shell non malignant.

Thank you for video

[@veronicanoordzee6440]

@ 3:55 This means that ONLY THE SYMPTOMS can be treated with medication; sometimes over many years.

[@adamborg1]

Why is the tissue inside the granuloma so loose sometimes? As with the one in Mb Crohn of the last slide 4:32? It seems dense sometimes and loose other times. The looser the older? Loose because of apoptosis? Fat???

[@Pathologyminitutorials]

Granulomas do vary in appearance a lot. I would think older granulomas would be more dense when they become fibrosed.

A bit unfortunate that you didn't mark the different cells on your illustrations. This might be shocking to you, but we are not all pathology-students ;-) Thanks!

[@Pathologyminitutorials]

I will bear this in mind for future videos, thank you for your helpful comment.

Great video! Helped a lot, thank you so much!

My pleasure, thank you for the feedback! Have a great day and stay safe.

[@preetam_laskar]

I'm diagnosed with vocal cord granuloma, is it a serious issue or a common curable disease, feeling scared..

[@flaminmongrel6955]

granulomas are not malignant so i don't think its that serious but you should consult your doctor instead.

[@lenababyyy1482]

Should I goto the dr orrrr

[@lenababyyy1482]

How is Ghon's focus different from granuloma in tuberculosis?

Thank you for this video. I loath every microbe that causes any effect to humans, I wish to eradicate them all.
Many thanks,

[@cnacma]

There are literally trillions of beneficial microbes in our body that we couldn’t live without

[@yousefas4417]

Douglas Meyer Thank you for your reply. I obviously do not mean our loving microbiota as part of microbes that harm the body. Then again, opportunist infections are a thing. Perhaps you think differently than me because you were born via c section?

[@cnacma]

Yousef A S I was born analy

Does granoloma become benign or malignant

[@Pathologyminitutorials]

No!
