RAC9232 Lab gives you this p53 staining for signing off as control tissue. [M80s Right Cheek. Tumour 47mm diameter. Signed out by myself without IHC as FSCC-some KA-like features]. Comments to lab....??? #Dermpath #Immunohistochemistry

Atypical intraepidermal lymphocytes tagging along the basal epidermis with halos. No spongiosis. This case really doesn’t need immunohistochemisry to confirm #classic 😉

"Granulation tissue" is called like that because it forms small granules due to new vessel formation during the wound healing repair. Under the microscope, it looks like what you see in these pictures. #Pathology #GranulationTissue

🚨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! 😆🔬🧬

🚨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! 😆🔬

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. 😆🔬

#PathSky 15F, thumb mass. There are no relevant positive immunostains. However, FISH for DDIT3 amplification (not rearrangement) is positive. This is an excellent example of a GLI1-amplified sarcoma. This is a great paper from the MSKCC group. pubmed.ncbi.nlm.nih.gov/38934567/

Pseudoepitheliomatous hyperplasia and dermal granulomatous inflammation with multinucleated giant cells. That’s it? Nope, keep looking and you will find the cause of these histopathologic changes—Medlar bodies of chromoblastomycosis!
