1. How do we tell primary lung cancer from metastatic cancers from other sites?
It’s correct to say we should use all available clinical, radiologic and pathologic information, but that’s too vague to be helpful in a practical sense.
Here I offer some tips. #tweetorial2. This #pathtweetorial is applicable mainly to #pulmpath . The principles in each organ are different. A carcinoma in a lymph node is a metastasis by definition. Not so in lung or colon.
IMHO it’s a mistake to approach a carcinoma in the lung as carcinoma of unknown primary

1/ How about a #Tweetorial on immunotherapy in quiz and answer form? Let’s try it! I’ll post a quiz in one tweet and then the answer in the next, and so on. Scroll down to follow the thread!
How about a #Tweetorial with no ending? A document that can be added to at any time? Can it work? Let’s find out!

This #pathtweetorial will address the entity know as “talc granulomatosis” and review the literature, including old papers!
#pathology#pulmpath#granuloma2/ I did a quick search to find the first time “talc granulomatosis” was used as a term for lung lesions caused by excipients in pills, and came across this 1970 paper. Were Hopkins and Taylor the first to coin the term? Correct me if I’m wrong @yro854

Mini #tweetorial for anyone who wants to learn how to do a good PowerPoint presentation:
Tip 1: Look and sound bored. Sigh a lot.
Tip 2:
Look towards your PowerPoint and away from your audience. This way they will appreciate the back of your haircut and everyone can avoid awkward eye contact

1/ This is the beginning of a #tweetorial or #pathtweetorial on a mystery topic. Fear not, it’ll become evident soon what we’re talking about. But first I’ll show you an image. These serpiginous fibroblast plugs are diagnostic if organizing pneumonia (formerly BOOP) 2/ In MOST cases of organizing pneumonia seen on lung biopsy, the etiology is not evident on histology. But sometimes, there is a clue. Examine this pic closely and then see if you can answer the quiz in the next tweet in this thread.

What happens after you inhale Histoplasma into your lungs? Is #histoplasmosis always a deadly disease?
You are at risk if you live in the Ohio or Mississippi River valleys, go spelunking, or work with chicken coops 2/
Many (maybe most) people who inhale Histoplasma remain asymptomatic. Many have symptoms that mimic “the flu” and are treated as such. Only a minority of immunocompetent folks are seriously and acutely ill at first exposure. This is called acute pulmonary histoplasmosis.

1/ It’s time for a #tweetorial on hypersensitivity pneumonitis. It’s a greatly misunderstood entity. Potentially treatable, so can be very good news. OTOH, misdiagnosing UIP as chronic hypersensitivity pneumonitis can be very bad.
Follow this thread for a #pathtweetorial2/
Let’s start with a poll regarding a common misconception. What is the predominant inflammatory cell in hypersensitivity pneumonitis?

Tweetorial on carcinoid tumor of the lung. I’ll add to it little by little every week 😊
#pathology #pulmpath
1/ Carcinoid tumor is the lower grade end of the spectrum of neuroendocrine tumors in the lung.
Caution: lung terminology is different from GI tract terminology
2/
In the lung, the terminology is
✴️ Typical carcinoid tumor
✴️ Atypical carcinoid tumor
✴️ Small cell carcinoma
✴️ Large cell neuroendocrine carcinoma
We don’t terms such as “well differentiated NET” because...this is #pulmpath and we are special 😜
Based on the above, what is your initial thought?
2. 
@kriyer68 and @ariella8 you guys are on top of your game!
