BST Path Education

All things bone and soft tissue pathology, here to help spread knowledge to the masses.

This is excellent

Largest description of a recently described #bstpath entity, in @AJSPjournal. Proud to be part of this multi-institutional collaboration.

Outstanding work

[Greg Charville @Greg_Charville]

This is "cutaneous" syncytial myoepithelioma...of bone!

@JMcMahonG with @SintawatWang recognized that these morphologically distinctive tumors occur in diverse anatomic locations, including bone.

They have recurrent EWSR1::PBX3 fusions too!

Osteosarcoma or chondrosarcoma? Not such a simple question! #BSTpath

[BST Path Education @PathBst]

Check out the latest and greatest from @SintawatWang, @MichaelMichal28, @Greg_Charville, @JMcMahonG, published in #VirchowsArchive:

Non-cutaneous syncytial myoepitheliomas are identical to cutaneous counterparts.
Awesome!

More #PediPath, another rare entity:
Child with large soft tissue thigh mass.
Diagnosis? Next steps?
#BSTpath

[BST Path Education @PathBst]

Thigh mass biopsy from young adult. Differential? Next steps? Grade?
#BSTpath

[BST Path Education @PathBst]

Excellent work all! Yes, this is embryonal rhabdomyosarcoma with chemotherapy-induced cytodifferentiation. Some say portends a better prognosis, perhaps controversial (and therefore twitter appropriate). Location is classic. Great responses. #BSTpath #PediPath

[BST Path Education @PathBst]

3 year old patient with history of large orbital mass, s/p chemotherapy and now resection. Diagnosis?

@JMGardnerMD @kells108 @JMcMahonG @Greg_Charville @MdSuster @AndersMeyerMD @carina_dehner @MichaelMichal28 Great ideas all! Love the differentials. Agree with @GershonMD, this is tenosynovial giant cell tumor of prox thigh. Key to recognition is the larger epitheloid cells with peripheral rim of hemosiderin granules, so called ladybird cells. #BSTpath

[BST Path Education @PathBst]

Let's keep it going with back to school week. Adult patient: what is the site and diagnosis? #BSTpath #pathtwitter

[BST Path Education @PathBst]

@JMGardnerMD @kells108 @JMcMahonG @MdSuster @AndersMeyerMD @Greg_Charville @MichaelMichal28 Excellent work all! This is lipoblastoma. Clues are lobular architecture and fibrovascular septae at low power, spectrum of adipocyte maturation w/immature cells in myxoid areas, and zonal architecture with immature cells in periphery / adjacent to septae.

[BST Path Education @PathBst]

Since it's back to school season: this one's a foot mass from a toddler. Your diagnosis? Anything else in the differential?
#pedipath #pedspath #BSTpath #dermpath

[John Gross, MD @JMcMahonG]

Radiolucency in frontal bone

sagittal + axial CT.

Here’s a clue: Keep a low power impression

Mild expansive remodeling, cortical thinning, radial (spoke) trabecular bone radiating around a central lucency

Diagnosis?

@reith16 @ahlawat_shivani @LauraMFayad @LisaRooperMD

[BST Path Education @PathBst]

Totally agree with @carina_dehner: this is Paget's disease. The polarized image is so perfect.

[BST Path Education @PathBst]

Was on vacay with MrsPathBst (#WorkLifeBalance), now back with this classic case: adult patient, diffuse sclerotic L1 vertebra.

@kells108 @JMGardnerMD @JMcMahonG @MichaelMichal28 @MdSuster @Greg_Charville @AndersMeyerMD Correct - clear cell chondrosarcoma, great job all!

[BST Path Education @PathBst]

40 year old man. What is the diagnosis? Can you figure out the site? Let's get those #MSKrads and #BSTpath skills to work. #BSTpatheducation

Anyone up for some #lowpowerpath #BSTPath ? @PathBst
