PAX8 positivity in lower urinary tract urothelial carcinoma (including different clones)! Seen in pTa & invasive alike. Not just a peculiarity of upper tract urothelial Ca. Important #IHCPath fact to be aware of imo #GUPath #PathTwitter

Replying to @DanGrahamMD

great Q! No minimum quant per say I report any %, as long as it is def chorio (syncytios+admixed cytotrophs; often assoc w/hemm). fortunately, per this paper limited chorio (<5%) likely not prognostic anyhow, but for completeness and to correlate with serum HCG I report any
