Want to maximize Merkel cell carcinoma detection in sentinel lymph nodes? Go with panCK + INSM1 or panCK + SOX11. CK20’s sensitivity is just too low; its expression can be absent in up to 24% of MCCs. Check it out if you love #dermpath and #IHCpath. 😆🔬 #MDACCPath pubmed.ncbi.nlm.nih.gov/40505699/

A striking increase in gamma/delta T-cells in subcutaneous panniculitis-like T-cell lymphoma (SPTCL) can be a major diagnostic pitfall. Recognizing this pitfall is crucial to avoid misclassification. A must-read for fellow #dermpath and #hemepath enthusiasts! 😆🔬 pubmed.ncbi.nlm.nih.gov/40532089/

#USCAP2026 in TX is just around the corner! 😆🔬🤠 Excited to connect with incredible pathologists and #pathology trainees and to see the latest studies in #dermpath. As a bonus, here’s a special stain that turned into a bit of pareidolia. 👀
What do you see in it? #MDACCPath

Bit late in sharing this, but excited nonetheless! Here’s a report featuring another novel fusion, VIM::NTRK3, in a Spitz neoplasm. An educational case for anyone into #dermpath & #molepath combos! 😄🔬🧬 pubmed.ncbi.nlm.nih.gov/40591913/

Here is another study supporting the role of TRPS1 #IHCPath in MPDs/EMPDs, which my initial studies proposed 2–3 years ago. Despite the major pushback and rejection from the #dermpath community at the time, I am glad to see more and more studies confirming our initial impression. 😆🔬

Did you know “Pautrier microabscess” was mistakenly named after Pautrier? It was actually Darier who initially described it in MF, but repeated citation of incorrect information by US #dermpath led to this misconception. Don’t trust everything you see in the literature until you verify the facts! 😆🔬

Looking for a unique #pathology fellowship experience? 😆🔬 #MDACCPath has spots open! You’ll see once-in-a-lifetime cases (quite often) and learn from some of the best in the field. If you’re even a little interested, apply! You won’t regret it.

It’s been a while since I shared a case. Did you know this immunoprofile, especially the diffuse TRPS1 immunoreactivity, strongly favors primary EMPD over secondary EMPD? Give it a try if you haven’t used it in your practice. 😆🔬 #dermpath #IHCPath #MDACCPath

🚨Spoiler alert: Here’s a key pitfall almost no #dermpath textbook covers—SPTCLs can often show marked gamma/delta T-cell populations, mimicking pcGDTCL. A diagnostic trap you’ll want to know about. Our paper is coming soon—stay tuned! 😆🔬 #dermpath #hemepath #MDACCPath

🚨Spoiler alert: Primary cutaneous NUT adnexal carcinoma can metastasize—but long-term outcomes remain unclear. We're about to report an almost 20-year follow-up on this new entity. Stay tuned! 😆🔬🧬 #dermpath #pathology #molpath #IHCPath #MDACCPath
