🩸Short #HemePath AML subtype #PathTweetorial 🧵

This is AML w/ t(6;9). Can be a/w basophilia, but not always (couldn’t find in this case)

Review question: AML with t(6;9) is strongly a/w another genetic abnormality- Poll ⬇️

P.S. Always learning- feedback welcome!

A 65 year old male presented with low urine output and bone pain. On further investigation serum creatinine was high and the patient had low hemoglobin. Bone marrow biopsy showed finding in the image. What is your diagnosis? #pathtwitter #pathtweetorial #pathresidents #pathboards

#TGIF ! A pretty and not-subtle case of alpha-1 antitrypsin (A1AT) deficiency on liver biopsy.
✳️ Normal hepatocytes produce A1AT, so look for A1AT globules and overexpression on IHC (not necessary in this exuberant case). #GIpath #liverpath #pathboards
My first #PathTweetorial 👇

A 60 year old man presented with weakness. Laboratory studies were unremarkable except for absolute lympocytosis in the peripheral blood.Bone marrow biopsy showed finding in the image. What is your diagnosis? #pathtweetorial #pathboards #hematology #hematology boards #pathresident

In my last video, I briefly discussed my method for approaching & describing unknowns cases...

I also figured that it would make a great #pathtweetorial !
