Clear cell papillary renal cell carcinoma

Clear cell papillary renal cell carcinoma (CCPRCC) is a rare subtype of renal cell carcinoma (RCC) that has microscopic morphologic features of papillary renal cell carcinoma and clear cell renal cell carcinoma, yet is pathologically distinct based on molecular changes and immunohistochemistry.[1]

Pathology

CCPRCC classically has apical nuclei, i.e. the nucleus is adjacent to the luminal aspect.[2] In most glandular structures the nuclei are usually basally located, i.e. in the cytoplasm adjacent to the basement membrane.

They typically stain with CK7 and do not stain with TFE3 and AMACR.[1]

gollark: If you do want to do this sort of thing I would probably recommend python, because I arbitrarily like it.
gollark: https://www.dokuwiki.org/dokuwiki is what I use now, it's a selfhosted open source wiki with decent plugin support.
gollark: https://tiddlywiki.com/ is neat, https://github.com/athensresearch/athens/ could be good but is very experimental, https://obsidian.md/ is not open source but apparently runs on a directory of local markdown files so you don't have lockin issues, https://github.com/logseq/logseq apparently exists but I've never used it and it has a closed source backend, https://foambubble.github.io/foam/ is nice if you like VSCode.
gollark: There's lots of interesting ongoing development with graph-structured notes applications and such.
gollark: It has search and stuff.
