A rarity - colleague's case. Young man c/o testicular swelling for a month which he attributed to contact sports. Then upon workup was found to have a very high b-hCG and lung mets. Orchiectomy showed pure choriocarcinoma. This focus here shows LVI. #PathSky

A classic my breast attending would present on at conferences - usual ductal hyperplasia with comedo type necrosis. This finding was seen in a radial scar. Important not to overcall! #PathSky

Consult from a colleague. Radical prostatectomy for prostate cancer and incidental CIS cancerizing the ducts. A doubly justified surgery. #PathSky

Older woman with history of breast cancer. New focus found on imaging mid chemo regimen. My initial concern was heme related until these stained nicely for CAM5.2. This is treated invasive ductal carcinoma. #PathSky

Nothing particularly interesting - prostatic adenocarcinoma with a mitosis that reminds me of the Batwing. Also been experimenting with raw images on my iPhone and editing them. Curious if there's a difference in sharpness. #PathSky

Soft tissue mass in the axilla. S100 and SOX10+, no h/o skin malignancies. An example of a Schwannoma with ancient changes. #PathSky

Biopsy of one of multiple white patches seen in esophagus. H&E showed no acute inflammation and only the barest hint of parakeratosis. No glycogenic acanthosis either. GMS teased out these critters. #PathSky

Another case from this past week. Lung biopsy for new lung nodule suspected to be cancer. Nearly thought I had to sign out medical lung but then I saw granulomas with asteroid bodies. And then the numerous yeast! Currently pending cultures and PCR. #PathSky

A slightly messy set of pictures. Young female, breast mass, post partum. This is a lactating adenoma with infarction. I love seeing entities I only previously read or heard about. #PathSky

Gastric biopsy in an older male with a history of anemia. If I weren't in private practice I would have done the iron stain but I did the next best thing and confirmed he was taking iron sulfate. #PathSky

Colleague's case. They were very kind to share this with me. There was a clinical concern for malignancy and this biopsy thankfully will get the patient the appropriate line of treatment. Likely hepatic sarcoid. #PathSky

For some reason the clinician didn't think this was a horn. Regardless, a beautiful little squamous cell ca in situ. #PathSky

No shade to my GI peeps but I feel like I rarely get good pancreatic FNAs. This was a great one and stained nicely with INSM1, synapto, and chromo. Overkill IHC but it was nice to see. #PathSky

I've officially made a work enemy ❤️ Anyhow something that stuck with me since residency is how these adenomas can have a shuttering artifact. Unsure why they do that. A soft sign of sorts at best. #PathSky

Looks like pleomorphic/grade 3 lobular initially. E-cad only partly lost and p120 catenin had mixed membranous and cytoplasmic expression. Areas with ductal feat elsewhere. Final dx - Invasive carcinoma with ductal/lobular features. #PathSky

A whole lotta acute inflammation and debris in a prostate, no carcinoma. If you're ever curious about whether or not there's real necrosis, I think this helps out. Unless you see actual cells dying into the lumen, don't call it pattern 5. It could just be inflammatory debris 🤷🏻‍♂️ #PathSky
