The answer to #ParasiteCaseOfTheWeek 820 is an onchocercoma due to Onchocerca volvulus! 🪱
This beautiful histology shows an adult female packed with developing microfilariae—and even a microfilaria that has escaped into the skin.

Some beautiful views on the North Shore of #Pittsburgh this morning as the city reflected in the mostly calm Allegheny River. The Highmark Building was lit up in honor of metastatic breast cancer awareness (as was the Koppers Building), and it made for incredible scenes.

Interestingly, sarcomatoid lung carcinomas are also almost always very high PD-L1 as shown by @VamsiVelcheti many years ago
Dedifferentiated and undifferentiated melanomas remain underrecognized with significant treatment implications - @aubre_gilbert shows that PD-L1 can provide a useful diagnostic hint (not just a predictive marker!). @StanfordPath @JHUPath
.@PamMichelow is one of the greatest pathologists I know, and someone I aspire to be like. #PathX #Cytopath

Cytomegalovirus on ROSE. The inclusions are evident on DQ and Pap. Cell block is loaded. CMV stain is great too! 👀🦉🔬 #cytology #cytorocks
Saving this for the weekend so I can read it with a good cup of coffee. Very timely and something I have been thinking about a lot! #PathX
For >300 years, pathologists learned by looking through a microscope. With digital pathology the multi headed scope is disappearing. Or is it multiplying?
A personal reflection on mentorship, digital pathology, and learning to see.
The posture is different. The eye is the same.

@UPMCPath PGY2 @LikeWorldPeace recently participated in the #CAP26 residents forum in beautiful Las Vegas! Pathology is such a small world, and conferences are an excellent opportunity to connect and collaborate with fellow pathologists and old friends from across the country.

Is WHO and ICC joining back together?
We’re figuring it out at #EA4HP2026 in Berlin! 🇩🇪
Starting the Classification Advancement Meeting: looking forward to seeing where the next classification takes us.
