Come join us in pathology at @mdanderson.bsky.social ! A great opportunity with a fun and dynamic group! 🔬 #pathsky

October 1st, the start of one of my favorite months! One of my friends in IT made me this 3D printed brain 🧠 the spooky candies were a nice touch 🎃 #pathsky

Have also seen it stain pilomatrix-like carcinoma and some gliomas (one with a BRAF mutation).

Dural-based mass with dural tail

Negative for SSTR2, no evidence of STAT6 fusion, and strong CD56 staining

GLI1 amplification present

🧠 take home point: GLI1-altered mesenchymal tumors can occur in the CNS and radiologically mimic meningioma!

Targeting cells that form blood vessels in glioblastoma could improve treatment Targeting cells that form blood vessels in glioblastoma could improve treatment

MD Anderson research findings suggest that targeting interactions between some cells around the blood vessels could help make glioblastoma more vulnerable to treatment.

UT MD Anderson and Texas Children’s Hospital Announce Joint Venture to End Childhood Cancer

MD Anderson and Texas Children’s Hospital announce a transformational collaboration dedicated solely to pediatric cancer care. This new first-of-its-kind joint venture, which will launch in early 2026, has a single mission: to end childhood cancer. #EndCancer

Yes they are!

In honor of upcoming Valentine’s Day here is a classic example of rosette-forming glioneuronal tumor. These grade 1 tumors typically show a hotspot mutation in FGFR1 along with PIK3R1 or PIK3CA alterations and are usually found in the fourth ventricle 🌹 ♥️ 🥀 🧠 🔬 #pathsky #neuropath #medsky

TFE3

#PathSky 43F with a solitary lung mass. Relatively circumscribed, nests and interesting micropapillae of lightly eosinophilic epithelioid cells. Negative for everything except TFE3. Dx?

Recurrent YAP1-TFE3 Gene Fusions in Clear Cell Stromal Tumor of the Lung - PubMed Clear cell (hemangioblastoma-like) stromal tumor of the lung (CCST-L) is a recently described distinctive rare pulmonary neoplasm of unknown histogenesis and molecular pathogenesis. Only 7 cases have ...

This is a clear cell stromal tumor of the lung. They have YAP1::TFE3 fusions, which are also present in YAP1::TFE3-fused hemangioendotheliomas and some pulmonary PEComas. Abbas Agaimy described these. pubmed.ncbi.nlm.nih.gov/33899786/

Palpably unfair act is definitely entering the lexicon #eagles

Grateful to work with such a fantastic group to learn new things and help our patients the best we can! #pathsky #medsky

Nuclear staining for TTF1

Just like Texas rarely sees snow ❄️, every once in a while you will find a primary tumor of the posterior pituitary so keep it in mind during frozen section analysis! Here is a classic example of pituicytoma showing diffuse nuclear positivity for TTF1 #pathsky #neuropath #medsky 🔬 🧠

MUC4.

#PathSky 32M with extra-axial, dural-based, frontoparietal mass. Clearly malignant epithelioid cells arranged in cords and nests in a sclerotic background. Looks a lot like a sclerosing epithelioid fibrosarcoma, and it is strongly MUC4-positive. So, we’re done, right?

Nice!

😂 thanks! The upside to living in Texas is you get a beautiful mild winter after a brutally hot summer

Same specimen after polarization highlighting the refractory nature of the material

Asteroid hyalosis is an aging-associated condition of the eye where calcium and phospholipids build up giving the eye a grossly “glittery star-like” appearance (hence the name). Here is a vitreous cytology specimen before and after polarization showing the material 💫 👁️ #pathsky #medsky

Ours just turned 3 but went through a phase claiming a giant was in her room and so we have taken to “shooing the giant” so maybe you can shoo monsters too 😂 kids are so creative and weird but alas the solutions are usually equally creative and weird

We need more back up coconuts in this world 😂 🥥

Some tumor look-a-likes on this Friday:

Chordoid meningioma and chordoma can share similar features of cords of cells in a myxoid background. Chordoma shows diffuse nuclear Brachyury expression whereas chordoid meningioma is positive for SSTR2 helping to differentiate the two 🧠 #pathsky #neuropath
