Breast - Granular cell tumor They are inhibin positive, maybe a better stain that CD68 They are S100 and SOX10 positive CK and ER negative Pitfall ⚠️ - They can look compressed/elongated (pic 3) instead of epithelioid like cells - They can look like muscle (pic 4) Dr. Cimino-Mathews #BreastPath #PathX #Pathtwitter #USCAP #pathology

🚪 Every diffuse glioma must pass through the IDH Gate. Once you see it this way, you'll never forget the WHO classification of diffuse gliomas again. 🧠 Would love your feedback! 🎥 youtu.be/HFWUTw-GPN8 #Pathagonia #Neuropathology #Pathology #MedicalEducation #MedTwitter

@pacobravop Yep. Leish on left. Histo on right!

@Path4People Leish, but not 100% sure. It looks like they have a kinetoplast

You cannot definitively speciate it on H&E BUT based on morphology, which is Histoplasmosis v. Leishmania? #pathx #pathology #microx #microbiology #pathtwitter #pathcritters

@PathDocBoston 😂 😂 please do!

@Path4People The "Thymocyte" is inspirational. I may go for "Atrophic Thymocyte" in mine. Up for consideration.

60s M with a renal mass. What is your diagnosis? #PathTwitter @MGBpathology @MGHPathology

I always worry about missing #AIS on #papsmear (s). Then I see one and am reminded of the ABUNDANCE of material with classic features: ☢️elongated hyperchromatic nuclei 🦅feathering 🍳saucepan handles (elongated cytoplasm) 🤪crazy pavement (disorganised) #gynpath

@smlungpathguy Good point. Thank you, Sanjay!

@Path4People In real life there is also location (lung vs skin etc) and location (what is common where you practice). Add GMS to that and you have 100% accuracy in telling these 2 apart

@capo_cari Interesting. Didn’t know that horses can get leishmaniasis as well!

@Path4People Years ago, B4 I was a histotech, a recently imported horse from the Dominican Republic, that I was taking care of, develop lumps on his neck. The vet biopsied thinking glanders and was surprised by leishmaniasis.
