📢 #Pathology #tweetorial alert!
⚕️ Dx: Plexiform #Schwannoma (aka neurilemmoma)

🔬 Multiple (2-50) nodules or foci of fascicular expansion.
🔬Biphasic: dense hypercellular areas (Antoni A) + loose hypocellular areas (Antoni B)

A plexiform multinodularity is typical of plexiform schwannoma on gross examination.
Usually sporadic (90%)
NF2 associated (5%)

NF2 gene on 22q12 ➡️ merlin.
Plexiform neurofibroma is associated with germline mutation of NF1 (17q11.2 ➡️neurofibromin)…

So the tumor is completely encased in the muscle, not contiguous with the compact bone.

1. #Breastpath Hey all, myofibroblastomas are really sweet. Let’s learn about them. @ADamronMD @TheKarenPinto @KRoSlideReview @Chucktowndoc @jennpincus @LizaMQuintana @drkennethtang @dr_MPrieto
2. Clinical: Uncommon tumors. Well circumscribed, may slowly enlarge over time. Size usu. up to 4cm. Historically (and on boards/RISE exams presently)more common in men, but now seem to occur equally in men and women.
3. A couple annotated low power pics.

What better way to kick-start the new year🎇than with a tweetorial/#RolaCoaster ?
Specifically made for the #pathtwitter family💝
Hope you enjoy the🎢!

Can you tell these 2 giant-cell rich lesions apart❓🧐

Answer is coming in Part2️⃣ of this #Tweetorial

▪️Why is this distinction difficult❓🤔
- Location is unknown
- Architecture not appreciated
- Age unknown

- Radiology is 🔑
(closest thing to gross
specimen is the black/

Painless hemiscrotal mass in a child, complex hydrocele on ultrasound.

Testis mass + smear... Fight!

#pedipath #gupath #cytopath
Rhabdomyosarcoma is indeed the top-level diagnosis... but more importantly, what type??

Note: several H&E patterns here that correspond nicely to the patterns on cytology.

#pedipath #gupath #pathology
Note the multiple patterns here - and see how they relate to myogenin staining.
This is an uncommon example of mixed-histology rhabdomyosarcoma.

Classic Embryonal - variable myogenin
Dense Emb/Solid Alveolar - strong, diffuse myogenin
Sclerosing - Weak/absent myogenin

Last night I posted this lovely gross picture; I’m now adding a couple of histologic images. Kudos to @kriyer68 and @DrAldehyde for being the first to submit the correct answer- this is indeed a synovial sarcoma! Not a bad time for a #Tweetorial #BSTPath
Synovial sarcoma is actually uncommon in joint cavities & does not recapitulate synovium in any way. Its rare amongst soft tissue sarcomas, representing only 5-10% of the cases. The disease is most prevalent in teenagers & young adults; 50% of cases are seen in pediatric patients
These most commonly present as pain in the affected site with an associated mass. In many cases the duration of symptoms is 2-5 years. They are seen most commonly in the extremities and are often associated with tendons. #BSTPath
